Nuclear Weapons

Latest missile launch appears to be a show of force since South Korea’s hypersonic missile test-fire, Seoul says.

North Korea has fired multiple ballistic missiles towards the sea off its east coast, South Korea’s military says.

South Korea’s Joint Chiefs of Staff (JCS) said one of the missiles flew more than 900km (559 miles) from the Pyongyang area on Monday. The joint chiefs did not specify how many missiles were detected.

Japan’s coastguard said on Monday that North Korea had fired two unidentified projectiles, believed to be ballistic missiles, which appeared to have already fallen.

South Korea’s presidential office said that Pyongyang’s repeated missile launches violate United Nations Security Council resolutions, urging an immediate stop.

Monday’s missile launch adds to heightened tensions on the Korean Peninsula, as both countries have been conducting weapons tests.

Escalating tensions

JCS spokesperson Jang Do-young said the latest missile launch appears to be a show of force since South Korea’s hypersonic missile test-fire.

On Thursday, South Korean President Lee Jae Myung oversaw the country’s first test-firing of a hypersonic missile, a rare public showcasing of a missile test by a South Korean president.

Lee’s office said the hypersonic weapon, once fully developed, would enhance South Korea’s ability to strike key targets by surprise in the “Korean Peninsula theatre of operations”.

On October 3, North Korea also tested a hypersonic intermediate-range missile designed to evade missile defences in South Korea and Japan.

Last week, Seoul demanded an apology after a landmine blast wounded three soldiers in the Demilitarized Zone between South and North Korea. A joint South Korean-UN investigation concluded that two landmines were planted by North Korean forces about a year ago. Pyongyang dismissed the claim and accused South Korea of provocation.

Prior to the border mine blast, Seoul said it was conducting “preliminary coordination efforts” to facilitate dialogue between Pyongyang and Washington.

Lee pledged to reopen dialogue with North Korea in his first speech after taking office in 2025.

North Korean leader Kim Jong Un continues to flaunt his nuclear weapons programme, while rejecting US and South Korean offers to resume stalled diplomacy.

Talks between Kim and US President Donald Trump abruptly ended in 2019. Kim Jong Un’s government continues to demand that Washington abandon its “hostile” policy towards Pyongyang and drop demands for North Korea’s denuclearisation as a condition for talks.

Putin warned the West he would deploy nuclear weapons if necessary to defend the Russian Baltic exclave of Kaliningrad.

Russian President Vladimir Putin has ruled out a ceasefire on long-range strikes with Ukraine as Moscow steps up its campaign of aerial attacks on Kyiv.

“We are told: ‘Let them stop striking your refineries, and you will stop striking their ships.’ It is simply ridiculous,” Putin said on Thursday at the Valdai political forum in Moscow.

The remarks followed a meeting between United States President Donald Trump and Ukrainian President Volodymyr Zelenskyy in New York on September 22, when Zelenskyy said Kyiv was ready to cease strikes on Russian oil refineries and other energy facilities if Moscow also stopped its attacks on Ukrainian energy infrastructure.

Speaking at the forum of the Moscow-based think tank, Putin said Ukraine had “partially achieved its objectives” with ⁠these strikes, with attacks on Russian ⁠oil refineries having cost the country 1 percent of its gross domestic product (GDP), but added that Russia ⁠was now responding in kind.

Russia has ramped up long-range strikes, targeting Ukraine’s steel companies as well as supply chains, notably in the rail sector. Ukraine accuses Moscow of deliberately hitting civilian targets and keeping Kyiv on a near-constant state of alert as it braces for another tough winter.

A Russian drone struck a school in Kyiv on Thursday, according to city officials, as the Ukrainian capital endured relentless aerial attacks. No casualties were reported as children and staff at the school were in shelters when the drone hit.

Putin added that Russia would prefer to end the conflict in Ukraine through talks and wanted it to ⁠be a neutral ⁠country after the end ⁠of hostilities.

The nuclear option

He warned the West not to escalate the standoff over Ukraine by threatening the Russian exclave of Kaliningrad, which is wedged between Poland and Lithuania, and pledged to defend it with nuclear weapons if necessary.

“If it comes to a direct attack on the Russian Federation – in this case, we are referring to Kaliningrad, and perhaps other territories as well – the question of the Russian Federation deploying all the weapons at our country’s disposal will, of course, inevitably and immediately be on the agenda,” he said.

Putin’s comments followed a diplomatic note which NATO said this week it had received from Russia, warning the Western military alliance it would be ready to resort to nuclear weapons if NATO attempted to cut off Russia’s Baltic exclave.

Putin warned that cycles of escalation in international conflict ⁠could quickly lead to dangerous scenarios. “We must realise that the moment when nothing can be changed any longer may come very quickly and unexpectedly for everyone. The logic of escalating, increasingly harsh retaliatory measures leads to a fatal point of no return,” ⁠he said.

On the contrary, in the event of a “favourable scenario”, Putin said the assets of Western companies that Moscow had seized could potentially be returned. Putin last month ordered the seizure of businesses and assets of Swiss food giant Nestle, French retailer Auchan, the former Leroy Merlin DIY chain and German wholesaler and food retailer Metro.

US president’s comments came after he was asked why North Korea can have nuclear weapons when Iran cannot.

United States President Donald Trump has described North Korean leader Kim Jong Un as “a friend” and played down concerns about Pyongyang’s nuclear arsenal, saying, “as long as I’m around, he’s going to be fine”.

Trump made the remarks in Washington, DC, on Tuesday after a reporter asked him why North Korea could have nuclear weapons but Iran could not.

“That’s interesting. You know why? Because you had a different president, and they could have stopped him,” he said, referring to previous US administrations.

“He happens to be a friend of mine, Kim Jong Un, he’s a friend of mine. He likes Trump, doesn’t like a lot of other people. I’m about the only person in the entire world that he likes, and I like him,” he said.

He said North Korea’s nuclear capacity was “pretty large” but “not like us”.

“You know what, as long as I’m around, he’s going to be fine,” he added. “You know why? Because he respects me and he likes me.”

South Korea’s Defence Minister Ahn Gyu-back said last week that its northern neighbour possessed between 80 and 120 nuclear warheads. The figure is significantly higher than Trump’s recent assertion that Pyongyang has 57 nuclear weapons.

Trump is seeking to re-engage with Kim and secure a win on the international stage as the US and Israel’s war on Iran enters its eighth month.

The US president launched the war along with Israel on February 28, saying Iran could not have a nuclear weapon. Iran has denied seeking a weapon, noting it had signed an agreement with world powers in 2015 that curbed its nuclear programme in exchange for sanctions relief. But Trump abandoned the agreement during his first term in 2018.

The US-Israel war on Iran has disrupted global energy supplies, raised fuel costs and hurt Trump’s popularity ahead of the November midterm elections.

Trump held summits with North Korea’s Kim in 2018 and 2019, but diplomacy broke down over US demands that Pyongyang give up its nuclear weapons. Since then, Kim has expanded his arsenal of nuclear-capable missiles and strengthened his diplomatic footprint by aligning with Russia over its war in Ukraine and tightening relations with China.

Trump had earlier said he planned to hold in-person talks with Kim before the end of the year.

But North Korea has not formally committed to such a meeting.

Indirect talks between the United States and Iran aimed at ending the seven-month-long war continue – most recently via Qatar as mediator on the sidelines of the United Nations General Assembly (UNGA) in New York – but the two sides still disagree about the agenda.

Iranian Foreign Minister Abbas Araghchi left New York on Tuesday after telling state-run Islamic Republic of Iran Broadcasting (IRIB) that he expects an official response to Tehran’s proposal to reopen the Strait of Hormuz by the end of the day. The proposal, which Iran said would see the strait reopened within seven days, was first passed to the US via Qatari mediators last week.

United States President Donald Trump was reported to have rejected that offer, under which Tehran would reopen the strait in return for Washington lifting its naval blockade, waiving sanctions, releasing an estimated $12bn in frozen Iranian assets and enforcing a wider regional ceasefire that includes Lebanon.

Under Iran’s proposal, wider peace talks, including discussions of its nuclear programme, would begin only then

Despite Trump’s public rejection, Araghchi says he has not yet received a formal response from Washington. Meanwhile, US media reports that Trump may well be willing to relax sanctions and unfreeze Iranian assets have been strongly denied by the US president.

Instead, US officials say, the US wants a deal that resolves all outstanding issues, particularly Tehran’s nuclear programme, in one go, rather than pursuing a gradual, step-by-step approach.

Here’s what we know about the talks:

Qatari mediators met Araghchi in New York on Monday to discuss how to advance Tehran’s proposal for reopening the Strait of Hormuz and then progressing to wider peace talks.

In a post on Telegram, Araghchi insisted that the talks focused solely on the Strait of Hormuz. He denied that the US had formally rejected the Iranian proposal.

“Despite what the US president said, I said that we were waiting for the official US response through the mediators … They [Qatar] had ideas, and we discussed them. They are going to raise this issue with the American side again, and then the final response from the American side will be conveyed to us through the Qatari mediator,” Araghchi said late on Monday.

Araghchi also said negotiations had become more “serious”, but cautioned that Tehran’s position has not changed.

“I state firmly that there has been no change in Iran’s position. Our conditions for opening the strait are clear. Our position on other issues is also clear. At present, there has been no discussion at all about flexibility,” he added.

Tehran’s proposal includes elements of the Islamabad memorandum of understanding (MoU), which was signed by both the US and Iran on June 17.

Is Trump willing to accept some Iranian demands?

A US official told The Associated Press news agency last week that Trump is not willing to make a final peace deal with Iran until the issue of its nuclear programme is addressed. According to the official, who has not been named, the US president would be willing, however, to grant Iran sanctions relief and release some frozen funds if progress is made on the nuclear file.

Then, on Monday, US-based news outlet Axios also reported that Trump had offered Iran sanctions relief in return for concessions on its nuclear programme. The report also cited US officials, one of whom told Axios that the indirect talks had been “positive and constructive”, adding that Tehran had indicated it was “flexible” on nuclear issues.

Trump, however, angrily denounced the story as a “hoax” in a post on Truth Social, the social media platform he owns. He said the story was “not true” and demanded Axios remove the article.

Iran has been heavily sanctioned for decades. The restrictions have severely affected Iranians’ quality of life, including their access to essential medicines and healthcare.

In August, the US announced yet more sweeping economic sanctions on Iran and countries that trade with it as it sought to apply more economic pressure to isolate the country from the global economy during the diplomatic deadlock in their war.

US Treasury Secretary Scott Bessent described the campaign as the “economic asphyxiation” of Iran.

It is difficult to quantify exactly how many Iranians have been killed by what Tehran views as “economic warfare”. However, a study published last year by the highly regarded medical journal The Lancet Global Health concluded that more than 564,250 people worldwide die annually as a result of US sanctions.

What does the US want?

In late February, just before the US launched its first strikes on Iran, the two sides were already holding talks hosted by Oman, which included the issue of Iran’s nuclear programme.

But before those talks could conclude, the US and Israel launched strikes, triggering the closure of the Strait of Hormuz, through which one-fifth of the world’s oil and natural gas is shipped in peacetime, by Iran. The closure of the strait has since become the primary point of contention between the two sides, when it had not been an issue before the war began. The strait is currently subject to blockades by both sides.

Throughout the war, Trump has repeatedly expressed his desire to strike a deal with Tehran. However, serious differences between the two sides will need to be resolved first, including the order in which issues are addressed for the purpose of peace talks.

Iran wants to establish its control of the Strait of Hormuz, have sanctions lifted and assets unfrozen, as well as ensure an end to US-Israeli strikes before it will go back to negotiating other issues, such as its nuclear programme. This was the order of events laid out in the MoU agreed between Iran and the US in June, but which quickly fell apart.

The US, however, wants everything to be on the table at the same time – it does not want to agree to anything relating to these Iranian demands before it addresses the other issues.

Scott Lucas, professor of US politics and international relations at University College Dublin, told Al Jazeera that Washington effectively wants Iran to surrender.

“The Strait of Hormuz has become a fundamental issue. The question here is, will both sides give? The memorandum of understanding clearly gave Iran a role in the management of the strait,” Lucas said.

“When the Trump administration pulled away from negotiating on the basis of the memorandum, they effectively went back to the idea of Iran having to completely allow passage through the Strait of Hormuz with no guarantees over it, in terms of not only what it means for Iran financially, but [also] in terms of Iranian security. The Iranian government is not going to agree to that, so we’re stuck in this limbo right now,” he added.

“Are the Trump folks going to come back to the talks on the basis of the memorandum of understanding or something that is a revised version of it, or are they going to try and break the government with economic warfare until at least after the US elections in November? That’s where we are right now.”

What does Iran want?

After half a century of bitter enmity with Washington, Iran wants to consolidate what it sees as the strategic gains it has made during a war it did not start. This specifically includes its newly established ability to close the Strait of Hormuz, sending global energy markets into a tailspin and placing additional pressure on the Trump administration.

Since US-Israeli strikes on Iran began on February 28, Hormuz has dominated talks aimed at ending the war and emerged as Tehran’s greatest point of leverage. Prior to the conflict, Iran did not exert control over the waterway and all commercial shipping passed through freely.

For this reason, Iran will not move on to wider peace talks until it has leveraged its control of the strait to get its demands met. “Our discussion is clear. Right now, it is only about the Strait of Hormuz,” Araghchi said late on Monday.

“The opening of the Strait of Hormuz is also subject to the fulfilment of a series of conditions that we announced to the other side.”

Ali Salehian, director of the Center for Intellectual Diplomacy at the Governance and Policy Think Tank in Iran, told Al Jazeera that Tehran does not believe Washington will honour any future deal as it did not honour what was agreed under the Pakistan-brokered June MoU.

“For Iran, the bottom line of every negotiation with Trump, considering all of his misbehaving and [military] targeting of Iran during negotiations, is the Islamabad MoU,” Salehian said.

“Tehran thinks that if the US doesn’t fulfil its commitments based on the MoU, there is no guarantee that any kind of future deal would be sustainable.”

What is likely to happen next?

It does not look likely that the diplomatic standoff will be eased anytime soon, analysts say.

Both the US and Iran have indicated throughout the war that they would prefer a diplomatic settlement to a continuation of the war. However, Trump has continued to threaten Iran with more strikes if it does not agree to a deal, and Araghchi told US news outlet NBC on Sunday that Tehran is also prepared to resume fighting, even though it has not abandoned diplomacy.

“We are fully prepared for the time for the war to be resumed, and I repeat, we stand firm in the face of any new aggression, even if it comes to a doomsday war,” he said.

Trump said last week that he expects a deal will be reached, but not until after the US midterms on November 3.

“For the moment, the Trump administration is going to try to make the Iranian government capitulate through economic warfare,” Lucas said.

However, a deep sense of distrust remains between the two sides. Senior Iranian officials believe Trump will restart the war after the midterms on a far greater scale and that Israel would also participate.

If that theory proves true, Tehran may well prefer the fighting to resume before November’s elections, as it would allow Iran to impose a greater cost on Trump.

“The reaction of the Iranians to that might be to actually trigger the war themselves, early, right before the midterm elections in order to maximise the pain that [it] will impose on the US president,” Trita Parsi, executive vice president of the US-based Quincy Institute for Responsible Statecraft, told Al Jazeera earlier this month.

As part of previous negotiations aimed at ending its war on Iran, the United States offered to sell Tehran uranium for use in a civilian programme, but Iran refused, a top US official said on Sunday.

“Heck, our negotiators even offered to sell them uranium,” US Ambassador to the United Nations Mike Waltz said on NBC’s Meet the Press. He said the agreement would have been akin to that with the United Arab Emirates, which has “a peaceful programme, right there in their neighbourhood, and they abide by international law and inspection regimes”.

Waltz said the administration of US President Donald Trump was open to allowing Iran to keep a civilian nuclear programme, provided it agreed to its obligations in accordance with international law and the Nuclear Non-Proliferation Treaty (NPT).

There were “a number of ways” President Trump was open to dealing with Iran to ensure it did not have access to highly enriched uranium, or the ability to reconstitute highly enriched uranium, including by having Tehran “hand over” any such material it currently has, Waltz said.

The UAE, a signatory to the NPT, generates electricity from a nuclear power plant and signed an agreement with the US in 2009. Under those agreements, the UAE has agreed not to produce enriched uranium domestically, and not to reprocess spent fuel on its own. Trump said Saudi Arabia and the US reached an agreement on civilian nuclear use this year, but details have not yet been made public, and the US president has also claimed the deal is contingent on Riyadh agreeing to the controversial Abraham Accords. Around the region, Egypt and Turkiye also operate civilian nuclear programmes.

Pakistan openly operates a nuclear arsenal, while experts have long believed Israel secretly possesses one of its own. Neither country is a signatory to the NPT.

A key point of contention between Iran and the US has been what should be done with the uranium that Tehran currently has, and how, or even if, to ensure any future supply of the material is not capable of being used for producing a nuclear weapon. Iran has insisted it has no plans to create a nuclear weapon, and any uranium it possesses and enriches is only for civilian purposes, including for generating electricity and use in medical treatments and scientific research.

Iran is estimated to have more than 440kg (970lb) of uranium enriched at 60 percent purity. Uranium enriched to around 90 percent purity is suitable for a nuclear weapon. Enriching uranium is a complex process that involves isolating the most radioactive isotope in a quantity of uranium. Under the 2015 Joint Comprehensive Plan of Action (JCPOA), Iran agreed to cap its uranium enrichment at 3.67 percent under strict international supervision in exchange for lifting sanctions against its economy. Trump scrapped that deal in 2018, saying it was too generous to Iran.

On September 10, the International Atomic Energy Agency (IAEA) said it was concerned over Iran’s “continued noncompliance” with the Nuclear Non-Proliferation Treaty, of which it is a signatory. Under the treaty, Iran agrees not to produce nuclear weapons and to meet IAEA safeguards to control its supply of uranium used for civilian purposes. The agency has not had access to key Iranian nuclear facilities since June 2025, when Israel and the US attacked sites in the country as part of a 12-day war.

Iranian officials have responded to the IAEA by saying the finding was made “under political pressure from the US and its allies”, and that they have not stopped respecting their treaty obligations, but could not allow inspections until facilities were safe from US and Israeli attacks.

At times, Trump has said he will destroy the enriched uranium Iran has or retrieve it by force. In April, the US president claimed to have convinced Iran to turn over the enriched uranium it had, which he referred to as “nuclear dust”. Iranian officials quickly dismissed those claims, saying enriched uranium would not be transferred outside the country under any circumstances.

On Saturday, Trump rejected a plan submitted by Iran to reopen the Strait of Hormuz within seven days, as Tehran continued to insist that only diplomacy can solve the conflict between the two countries. Speaking to reporters at the White House, Trump said on Saturday that Iran wants to make a deal to open the vital maritime corridor immediately only “because they are losing so badly”.

In an interview on Meet the Press on Sunday, Iran’s foreign minister, Abbas Araghchi, said that Iran is prepared for war to resume, “even if it comes to a doomsday war”.

He added, “If you ask us, there is no reason why we should go back to diplomacy. But I’m still trying diplomacy, because I think we shouldn’t miss any chance for peace.”
