Negotiators from Russia and the United States have met in the US city of Miami as Ukrainian President Volodymyr Zelenskyy urged Washington to ramp up the pressure on Moscow to end its war on Ukraine.

The meeting on Saturday took place between Russian President Vladimir Putin’s special envoy, Kirill Dmitriev, and US President Donald Trump’s special envoy, Steve Witkoff, and his son-in-law, Jared Kushner.

Dmitriev told the reporters the talks were positive and would continue on Sunday.

“The discussions are proceeding constructively,” said Dmitriev. “They began earlier and will continue today, and will also continue tomorrow.”

Earlier, US Secretary of State Marco Rubio had said that he may also join the talks in Miami. He said that progress has been made in discussions to end the war, but there is still a way to go.

“The role we’re trying to play is a role of figuring out whether there’s any overlap here that they can agree to, and that’s what we’ve invested a lot of time and energy [on], and continue to do so,” Rubio said. “That may not be possible. I hope it is. I hope it can get done this month, before the end of the year.”

Trump’s envoys have for weeks been negotiating a 20-point peace plan with Ukrainian, Russian and European officials.

While US ​officials say they have made progress, major differences remain on the issues of territory and possible security guarantees that Kyiv says are essential for any agreement.

Russia has shown few signs that it is willing to give up its expansive territorial demands in Ukraine, which it believes it is well-positioned to secure as the war grinds on and political fractures emerge among Ukraine’s European allies.

In Kyiv, Zelenskyy said he remains supportive of a US-led negotiations process, but that diplomacy needs to be accompanied by greater pressure on Russia.

“America must clearly say, if not diplomacy, then there will be full pressure… Putin does not yet feel the kind of pressure that should exist,” he said.

The Ukrainian leader said Washington has also proposed a new format for talks with Russia, comprised of three-way talks at the level of national security advisers from Ukraine, Russia, and the US.

Zelenskyy expressed scepticism that the talks would result in “anything new”, but said he would support trilateral discussions if they led to progress in areas such as prisoner swaps or a meeting of national leaders.

“If such a ‍meeting could be ⁠held now to allow for swaps of prisoners of war, or if a meeting of national security advisers achieves agreement on a leaders’ meeting… I cannot be opposed. We would support such a US proposal. Let’s see how things go,” he said.

The last time Ukrainian and Russian envoys held official direct talks was in July in Istanbul, which led to prisoner swaps but little else.

The talks in Miami come after Putin promised to press ahead with his military offensive in Ukraine, hailing Moscow’s battlefield gains in an annual news conference on Friday.

Putin, however, suggested that Russia could pause its devastating strikes on the country to allow Ukraine to hold a presidential ballot, a prospect that Zelenskyy rejected.

Meanwhile, the death toll in Ukraine’s Black Sea Odesa region from an overnight Russian ballistic missile strike on port infrastructure rose to eight, with 30 people wounded.

A civilian bus was struck in the attack, Ukrainian Prime Minister Yulia Svyrydenko said.

The Russian attacks on the coastline region have wrought havoc in recent weeks, hitting bridges and cutting electricity and heating for hundreds of thousands in freezing temperatures.

Moscow earlier said it would expand strikes on Ukrainian ports as retaliation for targeting its sanctions-busting oil tankers.

On Saturday, Ukraine claimed to have destroyed two Russian fighter jets at an airfield in Moscow-occupied Crimea, according to the security service SBU. Kyiv’s army said it struck a Russian oil rig in the Caspian Sea as well as a patrol ship nearby.

Putin described Russia’s initial full-scale invasion of Ukraine as a “special military operation” to “demilitarise” the country and prevent the expansion of NATO.

Kyiv and its European allies say the war, the largest and deadliest on European soil since World War II, is an unprovoked and illegal land grab that has resulted in a tidal wave of violence and destruction.

A Russian ballistic missile strike on port infrastructure in Ukraine’s Odesa port in the south has killed at least eight people and wounded 27, as Moscow intensifies attacks on the strategic Black Sea region and talks to end the war remain in a critical stage.

The attack late on Friday hit critical logistics infrastructure, with some of the wounded trapped on a bus at the strike’s epicentre as trucks caught fire in a car park.

Ukrainian officials say the bombardment is part of a sustained Russian campaign against Odesa’s civilian infrastructure that has left more than two million people without electricity, water and heating for days amid freezing temperatures in the war’s fourth punishing winter.

Moscow struck the same port again on Saturday, hitting reservoirs in what Ukrainian Deputy Prime Minister Oleksii Kuleba described as deliberately targeting civilian logistics routes.

The escalation comes as both sides trade blows across multiple fronts, while United States-led negotiations and numerous high-level meetings in Europe to end the war lumber on without a breakthrough.

Russia claimed on Saturday to have seized the villages of Svitle in the eastern Donetsk region and Vysoke in the northeastern Sumy region, though the reports could not be independently verified.

Ukraine has responded with a widening campaign against Russian military and energy assets.

On Friday night, Ukrainian drones struck the Filanovsky oil rig belonging to Russian energy giant Lukoil in the Caspian Sea, along with a military patrol ship patrolling near the platform.

The attack marked the first officially acknowledged Ukrainian strike on Caspian drilling infrastructure, though the rig had been hit at least twice before in December.

Between December 14 and 15, Ukrainian forces used sea drones to strike a Russian Kilo-class submarine at the Novorossiysk Naval Base in the Black Sea, according to a United Kingdom Defence Intelligence assessment.

Miami talks

The attacks unfold as American and European officials gather in Miami for weekend talks aimed at ending the nearly four-year war, with Russian and Ukrainian teams also in attendance.

Russian envoy Kirill Dmitriev said on Saturday he was heading to Miami.

US Secretary of State Marco Rubio said Washington would not force Ukraine into any agreement, though he described the conflict as “not our war”.

Trump envoys Steve Witkoff and Jared Kushner are leading discussions with Ukrainian negotiator Rustem Umerov and officials from the UK, France and Germany. Russian representatives, including Kremlin key negotiator Dmitriev, are meeting separately with American officials.

The key obstacle remains territorial concessions, with reports suggesting Washington is pushing Kyiv to cede parts of the eastern Donetsk region.

Russian President Vladimir Putin showed no signs of compromise at his annual choreographed news conference on Friday, pledging to press ahead with military operations and predicting new successes before the year’s end.

Putin’s remarks were the latest in a drumbeat of often-repeated maximalist Russian positions nearly four years after he ordered troops into the neighbouring country.

The issue of territory gained, lost, to be ceded or not, delves into the heart of the matter on one of the most contentious issues in the talks to end the war so far.

Putin has demanded Ukraine cede all territory in four key regions his forces have captured and occupied, along with Crimea, which Moscow seized and annexed in 2014.

He also wants Ukrainian troops to withdraw from parts of eastern Ukraine that Russian forces have not yet taken in the eastern Donetsk region, where fighting remains attritional – conditions Kyiv has rejected outright.

As talks continue, so does the fighting, with Russia controlling large parts of Ukraine’s eastern and Black Sea coastal regions.

Putin projected confidence on Friday about battlefield progress, saying Russian forces had “fully seized strategic initiative” and would make further gains before the year ends.

However, that narrative is on shaky ground this week, as Moscow’s assertion of inevitable victory flew in the face of facts on the ground.

Ukraine steadily took back control of almost all of its northern city of Kupiansk after isolating Russian forces within it, belying Russian claims to have seized it.

Russian forces were also unable to dislodge Ukrainian defenders from the eastern city of Pokrovsk in the eastern area of Donetsk to back up Moscow’s claims of total control.

Ukraine received a boost on Friday when European leaders agreed to provide a 90 billion euros ($105bn) loan to cover military and economic needs for the next two years.

President Volodymyr Zelenskyy, who met Polish President Karol Nawrocki in Warsaw the same day to reinforce regional unity against Russia, said the funds would go towards defence if the war continues or reconstruction if peace is achieved.

A key Russian airbase in occupied Crimea has been targeted by a Ukrainian drone strike, according to Ukraine. Authorities in Kyiv claim that drones hit a MiG-31BM Foxhound interceptor, as well as elements of an S-400 air defense system, at Belbek Air Base, near Sevastopol.

The Security Service of Ukraine (SBU), the government’s main internal security agency, reported that a successful drone strike operation was carried out overnight by forces from its Special Group “Alpha.” Russian officials, including the governor of Sevastopol, claim that the attack was repelled with 11 drones downed and resulted in no damage.

The SBU has published a series of video stills showing the attack, with footage taken from the perspective of the long-range one-way attack drones heading toward their targets. Based on the imagery, the drones could well be the same fiber-optic types that have been launched from Ukrainian drone boats.

Further videos were posted to social media by residents of Crimea, showing explosions and attempts by Russian troops to shoot down the drones. At this point, it should be noted that, without the full videos of the strikes, we cannot be sure whether the drones detonated or the degree of damage they might have caused.

According to the SBU, damage was recorded to a MiG-31, a 92N6 (NATO reporting name Grave Stone) long-range multifunction radar that is part of the S-400 system, two Nebo-SVU long-range surveillance radars, and a Pantsir-S2 surface-to-air missile system.

Ukraine claims that the targeted MiG-31 was carrying a full combat load, although the available video reveals that it carries no armament under its wings. Potentially, it carries air-to-air missiles below the fuselage, but the forward-mounted examples are also not visible. While it looks like a real aircraft rather than a decoy, it remains possible that it may have been a non-operational example. However, recent satellite imagery assessed by TWZ shows a MiG-31 sporadically at the base in recent weeks, sometimes sitting out in the open.

It’s worth noting, too, that the reported 92N6 system (seen below) was covered with camouflage and/or anti-drone netting, making its positive identification harder. It could also have been a 96L6 (Cheese Board) all-altitude detection radar, also associated with the S-400 air defense system.

As to the estimated value of these items of equipment, the SBU put a figure of $30-50 million on the MiG-31, depending on configuration and armament, $30 million on the 92N6, $60-100 million for each of the Nebo-SVUs, and $12 million for the Pantsir-S2.

“The SBU continues its effective work to destroy air defense systems in Crimea that cover important military and logistical facilities of the occupiers,” the agency said in a statement on its Telegram channel. “The elimination of components of this echeloned system significantly weakens the enemy’s defense and military capabilities in the Crimean direction.”

Belbek plays a key role in Russia’s war in Ukraine and, as such, has been targeted by Ukraine in the past.

The significance of the airbase, in particular, lies in the fact that its aircraft and air defenses help extend coverage deeper into Ukraine, as well as providing critical screening for the nearby Russian naval base at Sevastopol, and also extend this coverage far out into the Black Sea.

Belbek Air Base was used by Ukraine before Russia annexed Crimea in 2014. Today, it is home to the 38th Fighter Aviation Regiment (38 IAP, in Russian nomenclature), a unit that you can read more about here. When Moscow launched its full-scale invasion of Ukraine, Belbek received an influx of additional combat aircraft deployed from units in Russia. These have included examples of the Su-30SM and Su-35S, as well as Su-34 Fullback strike fighters, and MiG-31s.

MiG-31s, together with the very long-range air-to-air missiles they carry, have been a particular threat to the Ukrainian Air Force.

In October 2022, during take-off from Belbek, a MiG-31BM departed the runway, crashed, and was completely burned out. The navigator/weapons system officer ejected successfully from the rear cockpit, while the pilot was killed.

The airbase’s value means that it has received new hardened aircraft shelters and additional construction to help shield aircraft from drone attacks and other indirect fire. This is part of a broader push by the Russian military to improve physical defenses at multiple airfields following the launch of the full-scale invasion of Ukraine.

Notably, the MiG-31 was targeted while standing in the open, unprotected. Its twin cockpit canopies were open, suggesting it was being prepared for a sortie or had recently returned from one.

As well as previous drone attacks, Ukrainian forces have employed U.S.-supplied Army Tactical Missile System (ATACMS) short-range ballistic missiles with cluster munition warheads against the base, with a notably destructive ATACMS barrage in May of last year. That attack resulted in two MiG-31s being burnt out, confirmed in post-strike satellite imagery. Since then, however, the use of hardened aircraft shelters at Belbek will have made the resident aircraft less vulnerable to the effects of ATACMS armed with cluster munitions, in particular.

The Russian Aerospace Forces began the current conflict with around 130 MiG-31s in active service, a small number of them adapted to carry Kinzhal aero-ballistic missiles. The two aircraft destroyed previously at Belbek are the only confirmed combat losses, though thast ight change when more details of the latest drone strike become available.

The same attack on Belbek in May 2024 saw the Russians lose elements of an S-300 or S-400 air defense system, including what looked to be another 92N6 radar.

The targeting of Belbek again overnight, which Ukraine claims caused significant damage to prized air defense assets, shows that Ukraine is continuing to apply pressure on Russian forces in Crimea and is using a variety of weapons to achieve this.

Satellite imagery is now available showing the aftermath of a Ukrainian attack yesterday on a Russian Navy Improved Kilo class diesel-electric submarine in the Black Sea naval stronghold of Novorossiysk. The Security Service of Ukraine (SBU) claimed that this was the first attack against a Russian vessel using an uncrewed underwater vehicle (UUV). The operation could also mark the historic first successful use of a UUV as an anti-ship weapon, but the actual level of damage inflicted on the submarine remains unclear. Readers can first get up to date on the attack in our initial reporting here.

TWZ obtained satellite images of where the attack occurred in Novorossiysk from Vantor (formerly Maxar Technologies). Additional imagery from Planet Labs has also been circulating online.

The satellite imagery confirms that the UUV — named by the SBU as a Sub Sea Baby, a previously unknown type — detonated off the stern of the submarine, which was at a pier in the port of Novorossiysk. A substantial chunk of the pier itself was destroyed in the attack. This all aligns with video footage shot during the attack from a position on the ground nearby, which the SBU released yesterday.

The post-strike imagery shows that the Improved Kilo class submarine, also known as a Project 636.3 Varshavyanka class type, is in the same position as it was before the attack. Two other submarines that were moored nearby when the attack occured have moved. Other submarines and ships are still in the moorings, including on the outside edge of the damaged pier.

Some of the imagery available now suggests that the submarine that was attacked may now be sitting lower in the water, but that can’t be readily confirmed. Any damage below the waterline would also not be visible in the images. At the same time, there are also no clear signs of any emergency measures having been taken to keep it afloat, or to contain the leakage of oil or other potentially hazardous fluids, as one might expect to see if the damage was severe.

Based on the estimated length of what is visible of the submarine, some observers have noted that the epicenter of the explosion looks to have been less than 65 feet from the stern. The size and configuration of the Sub Sea Baby’s warhead, as well as other details about the UUV and its capabilities, remain scant.

To note, the stern section of Kilo-class submarine remains submerged so presumably it was even closer than 20 meters.

Highly probable that at least the propelled end got affected in a kinetic way.

It’s also worth noting that wider views of the port of Novorossiysk following the attack show four Project 636 submarines still present. There is nothing definitive to indicate that the targeted boat might have been replaced by another to conceal the extent of the damage.

For its part, the Russian Ministry of Defense had unsurprisingly denied that any damage was inflicted on the submarine or to any personnel at the port. The ministry has released a video that it claims shows the undamaged boat, but does not offer a view of the stern end. The background is also heavily censored. Even so, it does still reveal what looks like piles of broken concrete debris left on the pier after the explosion, which was clearly visible in the SBU’s video of the attack, as well as in the satellite imagery available now.

The press service of the Russian Black Sea Fleet, which operates the submarine, also denies any damage to its vessels. This is also consistent with reports from various Russian naval monitoring channels on social media, but clear corroborating evidence has yet to emerge.

Overall, at this stage, we still cannot say with any authority what degree of damage, if any, the submarine may have actually sustained.

On the other hand, the attack does show Ukraine was at least able to slip a UUV into a heavily defended harbor, in daylight, and detonate its warhead only a few dozen or so feet away from a prized Russian submarine worth, according to the SBU, around $400 million.

At least one Ukrainian UUV was therefore notably able to penetrate past barriers erected at the mouth of the port, intended specifically to protect the vessels within. It’s worth noting, however, that the defensive barriers Russia has already built around ports were primarily put there in response to Ukraine’s uncrewed surface vessel (USV) campaign. This underscores the significance of the use of a UUV in this attack, as another example of the steady adaptation of weapons systems and tactics in response to countermeasures that has become a particular hallmark of the conflict in Ukraine.

With that in mind, Russia is likely to introduce new countermeasures against this particular mode of attack, one which Ukraine has spent some time developing.

The results of yesterday’s attack, while inconclusive for now, will likely spur further such developments in Ukraine, as well. Before SBU targeted the submarine in Novorossiysk, Ukraine had unveiled a UUV dubbed Marichka, designed to launch kamikaze attacks against ships and maritime infrastructure. At least one other Ukrainian UUV, known as Toloka, has previously been disclosed. It’s unclear if either of these has any relationship to the Sub Sea Baby.

Video of the Toloka UUV:

Автономний підводний дрон TOLOKA

Furthermore, the attack confirms that the Black Sea Fleet is very much still a prime target for Ukraine. This applies especially to the submarines like the Project 636 types and corvettes that are able to launch Kalibr long-range cruise missiles. These weapons have been regularly used in Russia’s nightly barrages launched against targets across Ukraine.

Already, Ukrainian naval actions had forced the Black Sea Fleet to retreat from bases on the occupied Crimean Peninsula to Novorossiysk. Attacks in Crimea were also prosecuted against another Improved Kilo class submarine. In September 2023, the Rostov-on-Don was severely damaged during a combined missile and USV attack on Sevastopol. Ukraine later claimed it was destroyed.

At the start of Russia’s full-scale invasion of Ukraine, the Black Sea Fleet had a total of six Project 636 submarines available.

Other navies around the world will likely have watched yesterday’s attack with interest.

As well as the United States, China and many other nations are developing their own UUVs for missions like this one.

UUVs are able to attack vessels and other targets at long distances and can be launched from submarines and motherships, further extending their range. They can also be used for surveillance and mine laying, among other duties. You can read more about these vessels in various TWZ stories here.

Ultimately, whether or not the Russian submarine was damaged, the attack has demonstrated once again that the war in Ukraine is a crucible for the development of new military technologies, especially uncrewed ones.

Exiled punk band says its members are proud to be branded ‘extremists’ and hits back at Putin as an ‘aging sociopath’.

A Moscow district court has designated Russian punk protest band Pussy Riot as an extremist organisation, according to the state TASS news agency.

The exiled group’s lawyer, Leonid Solovyov, told TASS that Monday’s court ruling was made in response to claims brought by the Russian Prosecutor General’s Office and that the band plans to appeal. According to TASS, the case was heard in a closed session at the request of the Prosecutor General’s Office.

The court said that it had upheld prosecution submissions “to recognise the punk band Pussy Riot as an extremist organisation and ban its activities on the territory of the Russian Federation”, the AFP news agency reports.

An official Pussy Riot social media account shared a statement, responding defiantly to the ruling, saying the band’s members, who have lived in exile for years, were “freer than those who try to silence us”.

“We can say what I think about putin — that he is an aging sociopath spreading his venom around the world like cancer,” the statement said.

“In today’s Russia, telling the truth is extremism. So be it – we’re proud extremists, then.”

The group’s designation will make it easier for the authorities to go after the band’s supporters in Russia or people who have worked with them in the past.

“This court order is designed to erase the very existence of Pussy Riot from the minds of Russians,” the band said. “Owning a balaclava, having our song on your computer, or liking one of our posts could lead to prison time.”

According to TASS, earlier reports said that the Prosecutor General’s Office had brought the case over Pussy Riot’s previous actions, including at Christ the Saviour Cathedral in February 2012, and the World Cup Final in Moscow in 2018.

Today Russian court designated Pussy Riot as an extremist organization.

The band’s members have already served sentences for the 2012 protest at the cathedral in Moscow, where they played what they called a punk prayer, “Mother of God, Cast Putin Out!”

Nadezhda Tolokonnikova and Maria Alyokhina, who were jailed for two years on hooliganism charges over the cathedral protest, were released as part of a 2013 amnesty, which extended to some 26,000 people facing prosecution from Russian authorities, including 30 Greenpeace crew members.

In September, a Russian court handed jail terms to five people linked with Pussy Riot – Maria Alyokhina, Taso Pletner, Olga Borisova, Diana Burkot and Alina Petrova – after finding them guilty of spreading “false information” about the Russian military, news outlet Mediazona reported. All have said the charges against them are politically motivated.

Mediazona was founded by Alyokhina alongside fellow band member Tolokonnikova.

The news outlet says that it is continuing to maintain a verified list of Russian military deaths in Moscow’s war on Ukraine.

“We have confirmed 153,000 names, each supported by evidence, context, and documentation,” Mediazona said on Monday.

Ukraine’s state security service (SBU) said it carried out the first-ever uncrewed underwater vehicle (UUV) attack on a Russian vessel. The strike was on a Project 636 Varshavyanka class, or Improved Kilo class diesel-electric submarine, in the Black Sea naval stronghold of Novorossiysk. It would mark a historic first successful use of a UUV as an anti-ship attack weapon.

The SBU released a video it says shows the submarine docked at Novorossiysk along with several other ships. The video pans from right to left and at about the 16-second mark, the submarine erupts in an explosion. That means the UUV, which is not visible in the video, was able to navigate a packed harbor to strike a specific vessel. While we cannot independently verify the SBU claim about the use of a UUV in the strike, they did confirm that assertion to us directly.

Russia, meanwhile, denies any damage was caused by the attack.

‘The information disseminated by special services of Ukraine about the alleged ‘destruction’ of one of the Russian submarines in the bay of the Black Sea Fleet’s Novorossiysk naval base does not correspond to reality,” the Russian Defense Ministry (MoD) claimed on Telegram. “Not a single ship or submarine as well as the crews of the Black Sea Fleet stationed in the bay of the Novorossiysk naval base were damaged as a result of the sabotage. The watercraft serve normally.”

Today’s UUV attack appears to be the culmination of Ukraine’s development of these weapons and once again shows that the war-torn country is at the forefront of modern drone warfare innovation. Little is known about the Sub Sea Baby UUV, not to be confused with the highly adaptable Sea Baby uncrewed surface vessels (USVs) that have wreaked havoc on the Russian Navy.

Ukraine is developing several UUVs, at least that we know of. It released images in September 2023 of a UUV dubbed Marichka, designed to launch kamikaze attacks against ships and maritime infrastructure. That followed the announcement earlier that year of another UUV known as Toloka, which you can see in the following video.

Автономний підводний дрон TOLOKA

Being able to operate underwater not only helps greatly in avoiding detection and destruction, but it can also potentially mitigate some defensive barriers Russia has already built around ports as a result of Ukraine’s uncrewed surface vessel (USV) campaign. This onslaught has already kept Russia’s Black Sea Fleet (BSF) at bay, forcing it to retreat from Crimea to Novorossiysk. Ukrainian USVs have also damaged enemy military facilities in occupied Crimea and the Kerch Bridge, You can see one Ukrainian USV being destroyed below.

Russian Defense Ministry announced that Ukraine attempted to attack the Ivan Khurs signals intelligence ship of the Russian Navy with 3 unmanned surface vessels (USVs) in the Black Sea this morning.

The U.S., China and many other nations are developing their own UUVs for missions like the one that struck the Improved Kilo class submarines. UUVs can provide the ability to strike vessels and other targets at long distances and can be launched from submarines and motherships, extending their range. They can also be used for reconnaissance and mine laying, among other duties. You can read more about these vessels in our catalogue of stories here.

In the case of the Improved Kilo class boat, “the vessel suffered critical damage and was effectively put out of action,” the SBU claimed. “On board the submarine were four launchers for ‘Kalibr’ cruise missiles, which the enemy uses to strike at the territory of Ukraine.”

The submarine damaged by the Sea Baby UUVs is one of six Improved Kilo class boats that were operated by the Russian Black Sea Fleet, a retired Russian Navy officer who uses the @Capt_Navy X handle told The War Zone.

These submarines are quite capable and can be very hard to detect when dived and running on battery power. These submarines carry Kalibr long-range cruise missiles that have frequently been used to attack Ukraine.

The Sub Sea Baby UUV attack “was a joint operation of the 13th Main Directorate of Military Counterintelligence of the SBU and the Naval Forces of Ukraine,” SBU explained, adding that the estimated cost of one of the Russian submarines is about $400 million.

This incident also marks the second time an Improved Kilo class submarine in Crimea was attacked by Ukraine. In September 2023, the Rostov-on-Don was severely damaged during a combined missile and uncrewed surface vessel (USV) attack on Sevastopol. Ukraine later claimed it was destroyed. You can see the damage to that submarine below.

If today’s attack did damage the submarine significantly, Russia would be left with four examples operating as part of the Black Sea Fleet.

While much about the Sub Sea Baby UUVs remains a mystery, a proven ability to use them as weapons holds Russian vessels at even greater risk. Novorossiysk was seen as something as a relative safe haven for the Black Sea Fleet, although aerial and sea drone attacks have occurred there. But the idea that Ukraine can use underwater drones to strike ships in port there changes this calculus, if that is indeed the true method of the attack. As a result, we will also be seeing a change in Russia’s defensive posture at the sprawling port located on the northeastern edge of the Black Sea.

At the same time, if this attack was executed by a UUV, it would be another world first and is likely a harbinger of things to come. Hitting ships in port over great distances via underwater drone attack is an asymmetric capability. It’s also one that America’s adversaries are investing in heavily, and especially China.

With all this in mind, the attack on the submarine serves as another reminder that the war in Ukraine has become a conflict where theory and development are put into practice.

Dec. 15 (UPI) — Incoming spy chief Blaise Metreweli will use her first speech as head of MI6, Britain’s foreign intelligence service, to warn of the grave threat from Russia, particularly from its use of hybrid warfare.

The agency’s first woman head was set to warn of what she called “an acute threat posed by an aggressive, expansionist and revisionist Russia” and that its use of cyberattacks and drones meant “the frontline was everywhere.”

Metreweli, who took over from the outgoing “C,” Sir Richard Moore, on Oct. 1, will detail incidents of hacking and flying of drones near vital infrastructure by Russian proxies as examples of its use of hybrid tactics.

Russia has been waging this type of low-grade war on Ukraine‘s Western allies since Russia’s full-scale invasion in 2022, according to analysts, flying drones into NATO airspace neighboring Ukraine, disrupting flights by allegedly flying drones near European airports and cutting undersea cables.

In Britain, this has included recruiting Britons to spy for it, allegedly paying individuals to carry out an arson attack on a factory in London owned by Ukrainians and pointing lasers at RAF jets tracking Russian spy ships.

Speaking at MI6 HQ in central London, Metreweli was expected to vow Britain would not let up its campaign to impede Russian President Vladimir Putin’s aggression against Ukraine, noting recent sanctions imposed on Russian organizations and individuals the government believes were involved in information warfare.

“The export of chaos is a feature not a bug in the Russian approach to international engagement; and we should be ready for this to continue until Putin is forced to change his calculus,” she is expected to say.

As expected, Metreweli, who previously served as MI6’s technology and innovation lead, made famous by the character “Q” in the James Bond movie franchise, will stress the key role technology must play going forward.

She will urge intelligence officers to become technology experts “not just in our labs, but in the field, in our tradecraft.”

“We must be as comfortable with lines of code as we are with human sources, as fluent in Python [the computer progamming language] as we are in multiple languages.”

In September, MI6 launched Silent Courier, a secure messaging platform on the dark web, enabling spies to anonymously upload information useful to British intelligence from anywhere in the world. A YouTube video tutorial accompanied the launch.

Britain was, Foreign Secretary Yvette Cooper said “bolstering their efforts with cutting-edge tech so MI6 can recruit new spies for the United Kingdom — in Russia and around the world.”

The service also carried the following disclaimer from the Foreign Office.

“MI6 advises individuals accessing its portal to use trustworthy VPNs and devices not linked to themselves, to mitigate risks which exist in some countries.

“Do not use a name, phone number or other data linked to your real identity when creating this account,” it added.

A ceasefire deal appears distant as energy facilities are hit in Ukraine and Russia says a drone has killed two people.

Russian attacks have left thousands without power in Ukraine, while a drone attack killed two people in Russia, as United States-led peace talks on ending the war, deep in its fourth year, press on.

Ukrainian President Volodymyr Zelenskyy said Saturday that Russian night-time attacks damaged more than a dozen civilian facilities, disrupting power in seven regions.

“It is important that everyone now sees what Russia is doing… for this is clearly not about ending the war,” Zelenskyy said on social media. “They still aim to destroy our state and inflict maximum pain on our people.”

Kyiv and its Western allies have repeatedly said Russia is trying to cripple the Ukrainian power grid and deny civilians access to heat, light and running water for a fourth consecutive winter, in what Ukrainian officials call “weaponising” the cold.

Russian attacks left parts of the Kherson region, including the regional capital, Kherson, without power, according to regional head Oleksandr Prokudin.

Russian authorities in the southwestern Saratov region, home to an important Russian army base, said a drone killed two people and damaged a residential building. Several windows were also blown out at a kindergarten and clinic.

Russia’s Ministry of Defence said it had shot down 41 Ukrainian drones over Russian territory overnight.

The latest round of attacks came after Kremlin adviser Yury Ushakov said on Friday that Russian police and National Guard will stay on in eastern Ukraine’s Donbas, which comprises the fiercely contested Donetsk and Luhansk regions, and oversee the industry-rich region, even if a peace settlement ends Russia’s nearly four-year war in Ukraine.

Ukraine has rejected Moscow’s demands to maintain its presence in Donbas post-war as US-led negotiations drag on.

Germany is set to host Zelenskyy on Monday for talks as peace efforts gain momentum and European leaders seek to steer negotiations. US negotiators have for months tried to navigate the demands of each side as US President Donald Trump presses for a swift end to Russia’s war.

The search for possible compromises has run into a major obstacle over who keeps Ukrainian territory currently occupied by Russian forces. Ukraine, the US and European powers are also still trying to outline the contours of security guarantees for Kyiv that could be accepted by Moscow.

In the absence of a breakthrough in negotiations to end the conflict, hostilities recently intensified in the Black Sea, with Russian forces attacking two Ukrainian ports and damaging three Turkish-owned vessels, including a ship carrying food supplies.

An attack on the city of Odesa on Friday caused grain silos to catch fire at the port, according to Ukrainian deputy prime minister and reconstruction minister, Oleksii Kuleba. Posting video footage on social media of firefighters tackling a blaze on board what he described as a “civilian vessel” in Chornomorsk, Zelenskyy said the Russian attacks “had no … military purpose whatsoever”.

Turkish President Recep Tayyip Erdogan on Saturday warned that the Black Sea should not turn into an “area of confrontation”.

“Everyone needs safe navigation in the Black Sea,” Erdogan said, calling for a “limited ceasefire” in attacks on ports and energy facilities. Turkiye controls the Bosphorus Strait, a key passage for transporting Ukrainian grain and Russian oil towards the Mediterranean.

Dec. 12 (UPI) — Russia’s Central Bank has filed suit against the Belgian bank that holds about $217 billion in frozen Russian state assets to stop the European Union from using that money to make a large loan to Ukraine.

Most of Moscow’s frozen cash is held in Belgian bank depository Euroclear. The EU wants to extend a loan to Ukraine, which is running out of money to fight the Russian invasion of the country. But Russia wants to block that loan and accuses the EU of theft.

The Central Bank filed the suit in the Moscow City Arbitration Court as a warning to the EU. It said in a statement that Euroclear was participating in “unlawful activities” and that it filed the suit because the EU’s executive was “considering proposals for direct or indirect use of Bank of Russia assets without authorization.”

“A Moscow court cannot force Euroclear to comply, and any ruling would be unenforceable abroad,” said Alexandra Prokopenko, a former Russian Central Bank official and a fellow at the Carnegie Russia Eurasia Center, told The New York Times.

“But it is not meaningless: It creates formal documentation of Russia’s legal claims and serves as a political signal ahead of international litigation.”

Prokopenko also said an investment protection agreement exists between Russia, Belgium and Luxembourg that requires any loss to be compensated. That means Moscow could use that in future international arbitration against Belgium. So Belgium is worried about being left responsible in the future.

EU leaders will discuss the potential loan at a meeting Thursday in Brussels of leaders of all 27 member states. Belgium’s Prime Minister Bart de Wever was in London to meet with British Prime Minister Keir Starmer on Friday. The frozen assets were on the agenda, British officials have said.

European countries have been pushing Belgium to agree to the plan, but it’s trying to convince other countries to share the risk. Although most of Russia’s cash is at Euroclear, but smaller amounts are held in other European countries.

The loan plan would use the frozen assets to back a $106 billion loan to Ukraine, meted out over the next two years. Ukraine would only have to pay it back if Russia pays reparations.

Ukraine’s President Volodymyr Zelensky said about the funds, “It’s only fair that Russia’s frozen assets should be used to rebuild what Russia has destroyed — and that money then becomes ours.”

The loan plan could also cause a clash with Washington. In the U.S.-created peace plan that is still being negotiated, that frozen money was to be used to help rebuild Ukraine. But EU officials argue that if Ukraine falters financially, it will be in a weakened position in peace negotiations.

Using the frozen funds could “destabilize the international financial system,” Euroclear chief executive Valérie Urbain said.

“Belgium is a small economy,” Veerle Colaert, professor of financial law at KU Leuven University, told the BBC. “Belgian GDP is about [$661.5 billion] — imagine if it would need to shoulder a [$216.5 billion] bill.” She also said the loan may violate EU banking rules.

“Banks need to comply with capital and liquidity requirements and shouldn’t put all their eggs in one basket. Now the EU is telling Euroclear to do just that,” Colaert said.

“Why do we have these bank rules? It’s because we want banks to be stable. And if things go wrong it would fall to Belgium to bail out Euroclear. That’s another reason why it’s so important for Belgium to secure water-tight guarantees for Euroclear.”

A Russian Shahed kamikaze drone strike on a ship in the port of Chornomorsk was in retaliation for a recent spate of Ukrainian attacks on Russian oil tankers in the Black Sea, the Ambrey maritime security firm tells us. The attack on the Turkish-owned CENK-T roll-on, roll-off cargo ship comes after Russian President Vladimir Putin warned he would “cut Ukraine off from the sea” in response to Ukraine’s stepped-up campaign against Russian commercial shipping. 

As we have previously reported, Ukraine carried out three attacks on Russian-connected oil tankers in the Black Sea in late November and early December. Reports emerged on Wednesday that they carried out a fourth one, which you can read more about later in this story.

“This attack was the first retaliation,” Joshua Hutchinson, a former Royal Marine commando now serving as the company’s Managing Director of Risk and Intelligence, told us Friday afternoon.

Video emerging on social media showed several angles of the attack. One showed the Shahed flying over the port of Chornomorsk before the CENK-T‘s bow became engulfed in flames.

Early reports on this incident from both Ambrey and Russian media claimed Russia used an Iskander-M ballistic missile to carry out the attack, but the video clearly shows otherwise. While it’s possible another strike occurred using a ballistic missile, we have seen no evidence of it at this time.

A separate video showed different views of the 606-foot-long Panamanian-flagged vessel in flames following the strike. One view appeared to be across the harbor, while another was a closer view, dockside, with the ship burning and people running from the scene. The strike injured at least one person, according to Ambrey.

In addition to the CENK-T being hit, Ukrainian President Volodymyr Zelensky said several other targets in the Odesa region were attacked in a volley of missile and drone strikes. Though Russia has frequently attacked Ukrainian ports, this incident marks an escalation to the Black Sea shipping wars, increasing the danger to commercial vessels regardless of nation of origin, Hutchinson told us.

“We are heading to an uncharted time,” he explained. “We are now seeing two state actors attacking commercial shipping.”

While Russia has hit Ukrainian ports before, strikes on ships have been largely incidental. A concerted campaign against vessels would make shipping companies think twice before sending vessels into this area due to the risks to ships and crews. We saw that play out when the Houthis were attacking Red Sea shipping and a large percentage of companies opted to avoid the region. This would be very problematic for Ukraine.

The CENK-T was reportedly bringing in a shipment of generators, which Ukraine badly needs as Russia attacks its energy infrastructure. As we noted earlier in this story, on Dec. 2, Putin threatened to attack the shipping of nations helping Ukraine. We reached out to the vessel’s owner, CENK RoRo, for more information about the attack and how it will respond.

Zelensky decried the attack, saying it was another sign Russians aren’t interested in peace.

“Today’s Russian strike, like many other similar attacks, had, and could not have, any military sense,” the Ukrainian leader stated on X. “A civilian ship in the Chornomorsk port was damaged. This once again proves that the Russians not only do not take the current chance for diplomacy seriously enough, but also continue the war aimed at destroying normal life in Ukraine.”

The Russians have not officially commented on the CENK-T strike; however, Russian media acknowledged that it was in response to the attacks that damaged the four Russian ships and that the tempo could increase.

“Earlier, Vladimir Putin directly stated that the strikes by the Russian Armed Forces on Ukrainian ports are a completely justified response to Kyiv’s actions,” the Russian Readovka media outlet suggested. “At the same time, the sinking of just 10-15 ships in one port could paralyze its operations.”

The most recent of those took place on Wednesday when Sea Baby drones from Ukraine’s state security service (SBU) attacked the Serbian-flagged crude oil tanker Dashan in the Black Sea. Video of that attack showed the drones approaching the ship, which erupted in flames.

The Dashan attack, as we noted in our previous coverage, was preceded by others. On Dec. 2, a Ukrainian aerial drone struck the Russian-owned oil tanker Midvolga-2 about 80 miles north of the Turkish city of Sinop. A few days earlier, oil tankers, Kairos and Virat, were struck in quick succession off Turkey’s Black Sea coast by Ukrainian Sea Baby drones. These vessels are reportedly part of Russia’s “shadow fleet” that evades sanctions.

Ukraine, as we have frequently reported, is waging a campaign against Russia’s energy infrastructure involving numerous attacks on refineries, ports and other supply hubs inside Russia. The attack on the Dashan is a further indication that Ukraine is taking this fight to Russian vessels at sea.

Meanwhile, the Trump administration has reportedly signaled its support for the Ukrainian attacks on Russian vessels 

The Atlantic suggested that while the Biden administration feared escalation and opposed attacks on Russian vessels in international waters, Trump has taken the opposite tack. The publication reported that not only did the Trump administration not object to strikes, but in a number of cases, approved the transfer of intelligence to Kyiv, which was used to hit oil infrastructure facilities in Russia. The War Zone cannot independently verify that claim.

In the wake of today’s attack, Ambrey issued a warning to all ships making Black Sea port calls. These vessels “are advised to conduct comprehensive voyage threat assessments,” the company stated. “The crew is advised to remain within the designated Safe Muster Point (SMP) during missile attacks on infrastructure. The SMP should be located above the waterline, amidships and low-down in the superstructure.”

The coming days will tell if both parties continue to prosecute commercial shipping targets and what that could mean for maritime access to Ukraine.

Dec. 12 (UPI) — The German Foreign Ministry said it summoned the Russian ambassador Friday after accusing Moscow’s military intelligence of a cyberattack on air traffic control and attempted election interference.

A spokesperson for the ministry said a hacker group behind the 2024 cyberattack likely has ties to GRU, Russia’s military intelligence.

“We can now clearly attribute the cyberattack against German Air Safety in August 2024 to the hacker collective APT28, also known as Fancy Bear,” the ministry said, according to Euronews.

The ministry also said it can be “definitively stated” that Russia attempted to interfere in February’s general elections in an attempt to undermine government institutions and processes.

A Russian propaganda group called Storm-1516 is accused of launching a targeted disinformation campaign to influence the election. The group allegedly spread misinformation about ballot manipulation, Green Party candidate Robert Habeck and now-Chancellor Friedrich Merz, the BBC reported.

“Russia is thus very specifically threatening our security,” the ministry added.

Russia has claimed to be in full control of Pokrovsk, but Ukrainian forces say they still control the northern part of the strategic city in eastern Ukraine.

Ukrainian forces have reported an unusually large Russian mechanised attack inside the strategic eastern city of Pokrovsk, where Russia has reportedly massed a force of some 156,000 troops to take the beleaguered and now destroyed former logistics hub.

“The Russians used armoured vehicles, cars, and motorcycles. The convoys attempted to break through from the south to the northern part of the city,” Ukraine’s 7th Rapid Response Corps said in a statement on Wednesday regarding an assault earlier in the day.

A source in the 7th Rapid Response Corps told the Reuters news agency that Russia had deployed about 30 vehicles in convoy, making it the largest such attack yet inside the city. The source added that previously, Russia had deployed just one or two vehicles to aid troop advances.

While Russia has claimed full control of Pokrovsk, Kyiv maintains that its troops still hold the northern part of the city, where fierce urban battles continue to rage.

Russian troops have pushed into the city for months in small infantry groups, looking to capture the former logistics hub as a critical part of Moscow’s campaign to seize the entire industrial Donbas region of eastern Ukraine.

Video clips shared by the 7th Rapid Response Corps showed heavy vehicles in snow and mud, as well as drone attacks on Russian troops and explosions and burning wreckage.

Russian forces were attempting to exploit poor weather conditions but had been pushed back, the unit said on Facebook.

Capturing Pokrovsk would be Russia’s biggest prize in Ukraine in nearly two years, and the city’s weakening defence amid Moscow’s onslaught has added to pressure on Kyiv, which is attempting to improve terms in a United States-backed proposal for a peace deal that is widely seen as favourable to Moscow.

Ukraine’s top military commander, Oleksandr Syrskii, told journalists earlier this week that the situation around Pokrovsk remained difficult as Russia massed a force of some 156,000 around the beleaguered city.

Syrskii said Russian troops were staging the military buildup in the area under the cover of rain and fog.

George Barros, Russia team lead at the Institute for the Study of War – a US-based think tank – said Moscow is “hyping” the importance of the fall of Pokrovsk “in order to portray Russia’s battlefield advances as inevitable”.

“That sense of inevitability is being echoed by some members of President Donald Trump’s negotiating team trying to pull together a peace proposal for the Ukraine war,” Barros wrote in an opinion piece shared online.

But Russia has paid a huge price in its push to take the city with “more than 1,000 armoured vehicles and over 500 tanks” lost in the Pokrovsk area alone since the beginning of Russia’s offensive operations in October 2023 to seize nearby Avdiivka, which fell to Russian forces in early 2024 in one of the bloodiest battles of the war so far.

On Wednesday, President Trump said he had exchanged “pretty strong words” with the leaders of France, Britain and Germany on Ukraine, telling them their plan to hold new talks on a proposed US peace plan this weekend risked “wasting time”.

“We discussed Ukraine in pretty strong words,” Trump told reporters when asked about the phone call with British Prime Minister Keir Starmer, French President Emmanuel Macron and German Chancellor Friedrich Merz.

“They would like us to go to a meeting over the weekend in Europe, and we’ll make a determination depending on what they come back with. We don’t want to be wasting time,” Trump said.

The initial US peace plan that involved Ukraine surrendering land that Russia has not captured was seen by Kyiv and its European allies as aligning too closely with many of Russia’s demands to end the war, and has since been revised.

Trump has been pushing Ukrainian President Volodymyr Zelenskyy to agree to the US plan while Ukrainian officials told the AFP news agency on Wednesday that Kyiv had sent an updated draft of the plan back to Washington.

Firefighters evacuated residents and their pets from a nine-storey apartment building in Ukraine’s Sumy region after a Russian drone strike. The strikes come as Ukrainian President Volodymyr Zelenskyy met with leaders of the UK, France and Germany in London to discuss the US peace plan.
