Drone Strikes

A drone attack that caused a fire close to the Barakah Nuclear Energy Plant in the United Arab Emirates has raised further concerns about nuclear security and military escalation in the Gulf as discussions of peace between Iran and the United States hang in the balance.

Barakah was the first nuclear power station to be built on the Arabian Peninsula. Here is what we know about it:

What is the Barakah Nuclear Energy Plant?

Barakah is a nuclear energy plant located in Al Dhafra, the largest municipal region of the emirate of Abu Dhabi. It is the UAE’s only nuclear power plant.

Construction of the plant began in 2012, and its first reactor became commercially operational in 2021.

The plant is located close to the border with Saudi Arabia, about 225km (140 miles) west of the UAE’s capital city, Abu Dhabi.

The facility features four pressurised water reactors, the most common type of nuclear power reactor. The model used here is the advanced power reactor 1400, a pressurised water reactor design developed in South Korea. Each reactor of this type has the capacity to produce 1,400 megawatts (MW), which is enough to power roughly 1 million homes.

According to the Emirates Nuclear Energy Corporation (ENEC), the plant’s reactors produce 40 terawatt-hours (TWh) each year, which is equivalent to about 25 percent of the UAE’s electricity needs. The website for the London-based World Nuclear Association also confirmed that Barakah, when fully operational, meets 25 percent of the UAE’s electricity needs.

According to a September report by the Abu Dhabi media office, Barakah had produced 40TWh of clean energy over “the past 12 months”.

Since nuclear power plants produce a lower amount of carbon dioxide emissions than conventional power plants, the ENEC said Barakah saves up to 22.4 million tonnes of carbon emissions each year, equivalent to removing 4.8 million cars from the roads.

What happened in the attack on Sunday, and how has the UAE responded?

Authorities in Abu Dhabi said a single drone strike caused a blaze to break out at an electrical generator outside the Barakah plant’s inner perimeter in the Al Dhafra region on Sunday. No injuries were reported, and officials said radiation levels remained normal.

The UAE’s nuclear regulator said operations at the Barakah facility had not been affected. “All units are operating as normal,” it said in a social media post.

In a statement, the UAE’s Ministry of Defence said two more drones had been “successfully” intercepted and the drones had been launched from the “western border”. It did not give more details.

The UAE’s Ministry of Foreign Affairs posted a statement on X on Sunday saying the country condemned “the unprovoked terrorist attack” in “the strongest terms”.

The statement added: “The UAE emphasised that it will not tolerate any threat to its security and sovereignty under any circumstances, and that it reserves its full, sovereign, legitimate, diplomatic, and military rights to respond to any threats, allegations, or hostilities in a manner that ensures the protection of its sovereignty, national security, territorial integrity, and the safety of its citizens, residents, and visitors, in accordance with international law.”

There was no immediate claim of responsibility, and the statements by the ministries did not publicly blame any country.

But Anwar Gargash, an adviser to the UAE’s president, wrote in an X post on Sunday: “The terrorist targeting of the Barakah clean nuclear power plant, whether carried out by the principal perpetrator or through one of its agents, represents a dangerous escalation and a dark scene that violates all international laws and norms, in criminal disregard for the lives of civilians in the UAE and its surroundings.”

Gargash’s post appeared to blame Iran and its proxy network of allied armed groups in the region, which Tehran calls the “axis of resistance”.

The launch point of the drones remained unclear, but on Sunday, Saudi Arabia also reported it had intercepted three drones that had been launched from Iraq, where some Iran-allied groups operate. If Iranian Shahed-136 drones, which have an estimated range of 2,000km to 2,500km (1,240 to 1,550 miles), were fired from Iraqi territory, both Saudi Arabia and the UAE would fall well within their reach.

Other reactions

Neighbouring Gulf states Saudi Arabia and Qatar condemned the attack on the Barakah plant.

The Ministry of Foreign Affairs of Kuwait also issued a statement denouncing the attack, which it called “heinous”.

The Indian Ministry of External Affairs condemned the attack, calling it “unacceptable”, saying it represented “a dangerous escalation” and urging a return to diplomacy.

Has Iran responded to the incident?

Iran has not claimed responsibility for the drone attacks, and there has been no public statement from Iran about the incident at Barakah.

However, in the aftermath of the drone attacks, United States President Donald Trump wrote in a Truth Social post: “For Iran, the Clock is Ticking, and they better get moving, FAST, or there won’t be anything left of them. TIME IS OF THE ESSENCE!”

Iranian Ministry of Defence spokesperson Reza Talaei-Nik said on Sunday that the military is “fully prepared” to confront any new aggression from the US and Israel.

Iran has previously warned that countries where US military assets are deployed or Israeli-linked interests are located are viewed as legitimate targets.

Iran has also accused the UAE of strengthening ties with Israel while reports have emerged that Israeli Prime Minister Benjamin Netanyahu made a “secret” visit to the Gulf state during the US-Israel war on Iran. The UAE has denied this.

US Ambassador to Israel Mike Huckabee also said last week that Israel had deployed Iron Dome air defence systems and personnel to the UAE to help defend against possible Iranian attacks.

What has the IAEA said?

The International Atomic Energy Agency (IAEA), the global nuclear watchdog, said Sunday’s incident in the UAE had forced one reactor to rely temporarily on emergency diesel generators.

IAEA chief Rafael Grossi expressed “grave concern” and warned that military activity threatening nuclear facilities was “unacceptable”.

How serious could a strike on a nuclear facility be?

Attacks on nuclear power plants are especially worrying because they can risk damaging critical safety systems or reactors, which could release radioactive material into the atmosphere, not only over the country targeted but also across neighbouring states. Radiological material, specifically the hazardous isotope Caesium-137, could be released into the atmosphere.

The release of radioactive material could result in environmental contamination and poses major risks to public health. Water, if contaminated, becomes undrinkable while farmland and fisheries could become unsafe for decades, depending on the isotope released.

Short-term, acute exposure to radioactivity can cause burns and acute radiation sickness, which can be life-threatening.

Prolonged exposure, even to smaller doses, can increase the risk of illnesses such as cancer, especially thyroid cancer and leukaemia. Children and pregnant women are especially vulnerable.

Over the course of the US-Israel war on Iran, energy infrastructure has become a target.

Iran’s only functioning nuclear plant, the Bushehr power plant, has come under repeated attacks in the war. There are fears that damage at Bushehr could contaminate water across the entire Gulf region, most of which lacks groundwater and relies heavily on the desalination of seawater. Desalination plants are not specifically built to filter radioactive material, and not all plants currently are fitted with the technologies required to do so.

The killing of Izz al-Din al-Haddad, the recently appointed head of Qassam Brigades, the armed wing of Hamas, has dealt a symbolic blow to the Palestinian group in Gaza, but the impact on its military operations is far from certain.

Al-Haddad was killed on Friday in a sophisticated dual-strike on a residential apartment in Gaza City’s Remal neighbourhood and a vehicle attempting to flee the scene. The delivery of heavy munitions into a densely populated area, packed with displaced civilians, killed seven other Palestinians, including women and children, and wounded 50 people.

Yet, despite Israeli claims that the killing will cripple the group’s operational capacity, analysts argue that its decentralised nature is built to absorb such shocks. As the region watches to see how the resistance faction will respond, al-Haddad’s death raises critical questions about the future of the fragile “ceasefire” and who remains to lead the Qassam Brigades.

Operational impact: Will the Qassam Brigades collapse?

The killings of Qassam Brigades commanders, including Mohammed Deif, Marwan Issa, and Yahya Sinwar’s brother Mohammed, left al-Haddad as the key military figure managing the fight against Israel.

Saeed Ziad, a Palestinian political analyst, told Al Jazeera that while the loss is a “massive symbolic and moral blow” to Palestinians, the immediate operational impact on Hamas’s armed wing will be limited.

“The Qassam Brigades are not built on a hierarchical, sequential structure, but a parallel one,” Ziad explained. “Over the past two decades, Hamas has transitioned into a decentralised guerrilla force. Units operate as isolated, self-sufficient groups with their own logistical supply lines and combat doctrines.”

“If a brigade or battalion loses its commander, the group already knows its mission and has the resources to execute it independently,” he said. Reorganising the Qassam Brigades’ central command to cope with the loss will likely take mere days, not months.

Furthermore, al-Haddad had successfully utilised the October ceasefire with Israel to rebuild the group’s infrastructure. “Over the past 200 days, he reconstructed the resistance’s capabilities – its tunnels, weaponry and combat formations – making it capable of defending itself once again,” Ziad noted.

Who is left in the Hamas military leadership?

Israeli officials have boasted that they are close to dismantling Hamas’s central command, claiming that only two members of the military council before the pre-October 2023 attacks on Israel – Mohammed Awad and Imad Aqel – are alive.

However, analysts point out that Hamas’s military wing, which boasted roughly 50,000 fighters before the war, possesses a deep bench of cadres and a strict protocol for leadership succession that enables it to quickly recover when commanders are killed.

“The resistance typically appoints a first, second, and third deputy for every active commander, from the general commander down to the platoon leaders,” Ziad said. “Filling these voids happens rapidly.”

Hamas immediately confirmed Haddad’s death, with spokesperson Hazem Qassem officially mourning him as the “General Commander” of the Qassam Brigades. He stressed that despite his death being a “massive loss”, the group’s “long journey of resistance continues”.

The ‘Ghost’ of the Qassam Brigades

Born in the early 1970s, al-Haddad joined Hamas upon its inception in 1987. He rose through the ranks from an infantry soldier to commander of the group’s Gaza City Brigade, overseeing six battalions – each consisting of 1,000 fighters plus 4,000 support personnel.

He played a foundational role in establishing al-Majd – Hamas’s internal security apparatus designed to track down Israeli intelligence collaborators. But it was his ability to survive multiple assassination attempts – including bombings of his home in 2009, 2012, 2021, and three separate times during the current genocidal war on Gaza – that earned him the moniker “Ghost”.

Al-Haddad left an indelible strategic mark on the movement as a primary architect of the October 7, 2023 attacks. He personally oversaw the breach of the eastern fence, directed elite units that stormed the Re’im military base and the Fajja outpost. According to intelligence reports, it was al-Haddad who handed localised commanders a paper hours before the attack detailing the operation and ordering the capture of Israeli soldiers.

In January 2025, an Israeli air raid killed his son, Suhaib, but al-Haddad survived and continued to command operations and oversee the detention of Israeli captives until a deal was reached.

A fragile ‘ceasefire’ on the brink

Shortly after Friday’s strike, Israeli Prime Minister Benjamin Netanyahu and Defence Minister Israel Katz issued a rare joint statement, boasting that the killing was carried out under their direct orders.

Mohannad Mustafa, an analyst of Israeli affairs, said al-Haddad’s killing shows that Israel is attempting to “normalise” blatant violations of the “ceasefire” agreement, while the Netanyahu-Katz statement was an appeal to Washington to allow it to continue the killing campaign. At least 871 Palestinians have been killed since the “ceasefire” was announced on October 10, 2025, most of them civilians.

“Netanyahu is pitching this to the US administration as a necessary step to ‘disarm Hamas’ under the Trump plan,” Mustafa told Al Jazeera. “But the reality is that Israel never wanted this ceasefire. It was imposed on them.”

By systematically killing civilians, police, and military figures without offering immediate justifications for “ceasefire” breaches, Israel aims to provoke a response. “The ultimate goal is to force Hamas to retaliate, leading to the collapse of the agreement and giving Israel the green light to launch ‘Gideon 2’ – a military operation to occupy the entirety of the Gaza Strip,” Mustafa added.

With Netanyahu lacking a definitive strategic victory, such as the total surrender of Hamas, Ziad said the Israeli leadership is now leaning heavily on a “philosophy of assassinations” to project a “picture of victory” to its domestic base.

But history has shown that killings of leading military figures, such as al-Haddad, rarely have a significant long-term impact on armed Palestinian movements like Hamas.

“For the fighters and the society in Gaza, these killings create a blood covenant,” Ziad said. “It hardens their resolve. Retreating after the loss of leaders like Deif, Sinwar, or Haddad is viewed as a betrayal of that blood.”

Warring sides accuse each other of violations as attacks continue across front lines.

Russia and Ukraine have accused each other of breaching a short ceasefire announced by Moscow to coincide with Victory Day commemorations marking the Soviet Union’s defeat of Nazi Germany.

The Kremlin said its forces downed 264 Ukrainian drones early on Friday, with officials in Moscow reporting attempted attacks on the capital and in the Perm region in the Ural Mountains.

The truce, declared from May 8 to May 10, was intended to cover annual celebrations that include a military parade in Moscow.

Russia had warned that any disruption would trigger a large-scale missile response against Kyiv, urging foreign diplomats to leave the Ukrainian capital before potential escalation.

In a separate announcement, the Russian transport ministry said on Friday that 13 airports in Russia’s south halted operations due to drone attacks.

“Operations at the regional centre in Rostov-on-Don, which manages air traffic in southern Russia, have been temporarily suspended after Ukrainian drone struck the administrative building of the ‘Southern Russia Air Navigation’ branch,” the ministry said.

There were no casualties, it added.

Victory Day commemorations mark the Soviet Union’s loss of 27 million people in World War II, as it drove Nazi forces back to Berlin, where Adolf Hitler died, and the Red Army’s Soviet Victory Banner was raised over the Reichstag in May 1945.

‘We will defend our people’s lives’

Ukrainian President Volodymyr Zelenskyy said Russian forces continued to attack positions overnight, dismissing the ceasefire as ineffective.

He said Russia had carried out more than 140 attacks on front-line positions by early morning, alongside 10 assaults and more than 850 drone attacks.

“As we did over the past 24 hours, Ukraine will respond in kind today as well. We will defend our positions and people’s lives,” Zelenskyy said.

Ukraine also reported striking a Russian oil facility in Yaroslavl, deep inside Russian territory, in what Kyiv described as retaliation for attacks on its cities.

“Ukraine’s long-range sanctions continued in response to Russian strikes on our cities and villages,” Zelenskyy said.

Kyiv had proposed an open-ended ceasefire beginning on May 6, which it said Russia ignored. Moscow did not adopt that proposal, and neither side accepted the other’s terms.

In remarks before the truce, Zelenskyy criticised Russia’s approach to the commemorations, saying Moscow sought a pause “to hold their parade, to go out onto the square safely for an hour once a year, and then continue killing, killing our people and waging war”.

“The Russians are already talking about strikes after May 9. Strange and certainly inappropriate of the Russian leadership,” he added.

“Just as 81 years ago, so now America can help peace with a just and strong stance against the aggressor,” Zelenskyy said. “And it is important that the American people now view Russia precisely in this way – as an aggressor.”

US Defense Secretary Pete Hegseth says ceasefire with Iran remains in place despite growing tensions in the Strait of Hormuz.

The attack, the second in a week, follows months of relative calm in the city after government forces regained control last year.

A drone strike carried out by the paramilitary Rapid Support Forces (RSF) has killed five civilians in Khartoum, according to an NGO.

The attack, which Emergency Lawyers, an independent legal group supporting victims of human rights violations in Sudan, reported on Saturday, is the second to take place in the capital within a week. It follows months of relative calm in the city after government forces regained control last year.

The NGO said it holds the RSF fully responsible for the strike, accusing the group of breaching international humanitarian law.

Emergency Lawyers said the incident forms part of an ongoing pattern of attacks on civilians. Nearly 700 civilians were killed in drone strikes in the first three months of this year, according to UN figures.

‘Completely free’

On Tuesday, a drone struck a hospital in the Jebel Awliya area, around 40 kilometres (25 miles) south of central Khartoum, a security source and eyewitnesses told the AFP news agency. It was the first such attack in the area in months.

The Sudanese army, which now enjoys a solid grip in the north and east, launched a rapid counteroffensive last year that pushed the paramilitary forces out of the capital.

Following intense fighting around the capital last year, Sudan’s military government declared the Khartoum region “completely free” of RSF.

Since then, the RSF has largely concentrated on expanding its control in its stronghold in the western Darfur region and pushing into neighbouring areas, capturing valuable oil-producing assets.

Violence has also spread to southeastern Blue Nile state near the border with Ethiopia, raising fears of a more prolonged and fragmented conflict.

The RSF carried out a series of drone strikes on Khartoum last year, largely targeting military sites, power stations and water infrastructure.

In recent months, however, the capital has seen relative calm. More than 1.8 million displaced residents have returned, and the airport has resumed domestic flights. That said, much of the city remains without electricity or basic services.

The conflict between the Sudanese government and the RSF – a former ally – began in April 2023. Since then, around 14 million people have been displaced and two-thirds of the population are in urgent need of humanitarian support, according to the United Nations.

Ukraine’s attacks on Russia injure at least six people in the region of Vologda and the annexed Crimea.

Ukrainian officials say Russian attacks in several regions have killed at least five people and damaged a ship in the port of Odesa – as Moscow claimed to have intercepted more than 200 Ukrainian drones.

A Russian drone attack killed two men on Saturday in Ukraine’s northeastern Sumy region, according to Governor Oleh Hryhorov. He said civilians were hit in Bilopil close to the Russian border.

In the central Dnipropetrovsk region, Russian attacks on four districts killed one person and injured four others, Governor Oleksandr Ganzha said.

In the southern region of Kherson, Governor Oleksandr Prokudin said Russian shelling wounded seven people.

Further east, Russian forces launched more than 700 attacks on 50 settlements in the Zaporizhia region over the past 24 hours, killing two people and injuring four, according to Governor Ivan Fedorov.

Homes, vehicles and infrastructure were damaged, he added.

In Odesa region, Deputy Prime Minister Oleksii Kuleba said Russian forces again targeted port infrastructure.

“The attack damaged port and logistics infrastructure facilities, warehouses, technical equipment, cargo storage tanks, administrative buildings, as well as freight transport,” Kuleba said on Telegram.

He added that a civilian vessel flying the flag of Palau was damaged while loading in port. No injuries to the crew were reported.

Ukraine’s air force said it shot down or disabled 124 of 144 drones launched by Russia overnight with impacts recorded at 11 locations.

Russia reports Ukrainian drone attacks

Russia’s Ministry of Defence said its air defences destroyed 203 Ukrainian drones between Saturday evening and Sunday morning over Russian regions and the Black Sea.

The ministry said 95 Ukrainian drone control centres were destroyed over the previous 24 hours.

In Russia’s Vologda region, Governor Georgy Filimonov said five people were injured in a Ukrainian drone attack on a nitrogen complex.

In Sevastopol in Crimea, which was annexed by Russia, debris from downed drones struck the cardiology department of a hospital, injuring one person, according to Governor Mikhail Razvozhayev. He said 16 Ukrainian drones were shot down over the city overnight.

Razvozhayev added that drone debris also fell on rail tracks, damaging overhead power lines and causing train delays.

Peace efforts continue

The latest attacks came as diplomatic efforts to end the war, now in its fourth year, remained stalled.

Ukrainian President, Volodymyr Zelenskyy, said he signed agreements on security and energy cooperation with Azerbaijan’s President Ilham Aliyev in Baku on Saturday.

Zelenskyy said Kyiv wanted to draw on its experience defending airspace from Russian attacks. He also said he had discussed the possibility of holding future talks between Ukraine and Russia in Azerbaijan.

“We are ready for the next talks to be in Azerbaijan, if Russia will be ready for diplomacy,” Zelenskyy said.

Dozens of mourners, journalists and family attended the funeral of Amal Khalil, a Lebanese journalist who was killed in an Israeli attack in south Lebanon. Heidi Pett breaks down what we know about the incident, and Khalil’s last message to her family.

Plumes of black smoke were seen after Ukrainian drones targeted Russia’s Black Sea port of Tuapse. At least one person was killed. The strike was the second attack on the port in three days.
