Nuclear Weapons

Tehran, Iran – Another round of indirect talks between Iranian and United States officials ended with a mediator claiming “significant progress” but still no clear evidence that either side was willing to concede enough on their positions to avoid war.

After the conclusion of the talks in Geneva on Thursday, Iranian Foreign Minister Abbas Araghchi said further technical talks would be held next week in Vienna and progress had been “good”.

“These were the most serious and longest talks,” Araghchi said.

Omani Foreign Minister Badr bin Hamad Al Busaidi, who mediated the talks, said Iranian and US diplomats would consult with their governments before the Vienna talks.

Few details have emerged about the discussions, but Araghchi was reported to have met US envoy Steve Witkoff – if only briefly, according to Iran’s Tasnim news agency.

The Iranian team, led by Araghchi, handed over on Wednesday night Tehran’s written proposals to Al Busaidi, who also mediated previous rounds of talks in Geneva and Muscat.

The Omani diplomat then met with the US delegation on Thursday, led by Witkoff and US President Donald Trump’s son-in-law Jared Kushner. Al Busaidi mediated between the two teams throughout the day, and the US delegation also held separate talks over Ukraine.

Also taking part in the talks was Rafael Grossi, the director general of the International Atomic Energy Agency (IAEA), which will have to undertake nuclear monitoring and verification duties in Iran in case of any agreement.

The UN watchdog will hold several days of board meetings starting on March 6, which is around the 10- to 15-day deadline floated by Trump last week for Iran to reach a deal.

Western media outlets have suggested the board could once again consider a move to censure Iran depending on the results of the Geneva talks. Iran has accused Grossi of taking politicised action and criticised the IAEA after Israel attacked Iran in June, one day after the agency passed a resolution saying Tehran was not complying with its commitment to nuclear safeguards.

Fundamental differences

The two sides have been at odds over key issues, including uranium enrichment and missiles.

Washington has repeatedly emphasised, in lockstep with Israel, that it will not accept any nuclear enrichment taking place on Iranian soil, even at civilian-use levels agreed during the 2015 nuclear deal that Iran agreed with world powers. Trump unilaterally abandoned that deal in 2018.

In the days leading up to the Geneva talks, US officials increasingly focused on Iran’s ballistic missile programme, saying the missiles threaten US military bases across the Middle East as well as Israel. Iran has refused to entertain any talks on its conventional weapons. Iranian officials, including President Masoud Pezeshkian, have repeatedly said they will never develop nuclear weapons.

Speaking to local officials during a provincial visit, Pezeshkian also shot back at Trump’s assertion during a lengthy State of the Union speech that Iran was “the world’s number one sponsor of terror”.

Pezeshkian said numerous Iranian officials and nuclear scientists have been assassinated over the decades, particularly in the immediate aftermath of the country’s 1979 Islamic revolution.

“If the realities are seen fairly, it will become clear that Iran is not only not a supporter of terrorism, but one of the main victims of terror in the region and across the world,” he said.

The Iranian government’s IRNA news agency said Tehran’s proposal was expected to gauge US “seriousness” in the talks because it contained “win-win” offers.

Iranian officials have not publicly discussed all the details of their proposals, but they are believed to include diluting part of the country’s 60-percent enriched uranium and keeping the uranium inside the country. Iranian authorities envisage that could be paired with economic opportunities for the US related to Iranian oil and gas and the purchase of airplanes.

Supreme Leader Ali Khamenei has maintained his tough rhetoric against the US as well, casting doubt on the chances of any agreement. He also said Trump would be unable to overthrow Iran’s government after the US president said regime change would be “the best thing that could happen” in Iran.

Araghchi said during an interview on Wednesday that even if Khamenei is killed, the theocratic establishment in Iran would carry on because it has legal procedures in place to appoint a successor. Pezeshkian added on Thursday: “They can eliminate me, eliminate anyone. If they hit us, a hundred more like us will come up to run the country.”

Double-digit inflation as Iran braces for war

Iranian and US officials have been hailing supposed “progress” in the indirect talks this month, but many Iranians continue to prepare for war.

In Tehran and across the country, people are buying bottled water, biscuits, canned foods and other essentials in case of a war.

“A few days ago, I bought a power bank to keep the electronics charged. Now I’m looking for a short-wave radio so we can hear the news if the state shuts down the internet and electricity infrastructure is bombed,” said a 28-year-old resident of the capital who asked not to be named.

As bombs fell during the 12-day war with Israel in June, Iranian authorities cut off almost all internet access for several days, followed in January by an unprecedented 20-day total blackout imposed on about 92 million people as thousands of people were killed during nationwide protests.

The Iranian government, which blames “terrorists” armed and funded by the US and Israel for the protests, has rejected Trump’s claim that 32,000 Iranians were killed during the demonstrations. It said more than 3,000 people were killed, and rejects documentation by the United Nations and international human rights organisations that its security forces were behind the killings.

As the threat of war intensifies, not all Iranians are capable of stocking up on food and other necessities due to rising inflation that has gripped the country for more than a decade as a result of a mix of chronic local mismanagement and US and UN sanctions.

According to separate reports by the Statistical Centre of Iran and the Central Bank of Iran released on Thursday, inflation has now shot beyond 60 percent.

The Statistical Centre put annual inflation in the Iranian month of Bahman, which ended on February 19, at 68.1 percent, while the Central Bank said it was 62.2 percent.

Food inflation was by far the strongest driver at a whopping 105 percent. That included a 207-percent inflation rate for cooking oil, 117 percent for red meat, 108 percent for eggs and dairy products, 113 percent for fruit and 142 percent for bread and corn.

Iran’s national currency, the rial, stood at about 1.66 million rials to the US dollar on Thursday, near an all-time low.

Oman’s Foreign Minister Badr Al Busaidi has confirmed that further talks between the United States and Iran will take place on Thursday amid spiralling tensions between the two countries.

“Pleased to confirm US-Iran negotiations are now set for Geneva this Thursday, with a positive push to go the extra mile towards finalizing the deal,” Albusaidi said in a social media post on Sunday.

The announcement comes as the US continues to amass military assets in the Middle East, raising concerns about an all-out war against Iran.

Hours before Oman’s announcement, Iran’s Foreign Minister Abbas Araghchi said Tehran was ready to put in place a “full monitoring mechanism” to guarantee the peaceful nature of its nuclear programme and ease tensions.

Asked by Face the Nation moderator Margaret Brennan why Iran would want to pursue enrichment on its soil rather than buy enriched uranium from abroad, given the US military build-up and risk of an escalation, Araghchi said the issue was a matter of “dignity and pride” for Iranians.

“We have developed this technology by ourselves, by our scientists, and it is very dear to us because we have created it – we have paid a huge expense for that,” he said.

Araghchi cited among the costs two decades of US sanctions, the targeted killings of Iranian scientists, and US-Israeli attacks on nuclear facilities in June.

“We’re not going to give [our nuclear programme] up; there is no legal reason to do that while everything is peaceful and safeguarded” by the United Nations nuclear watchdog, the International Atomic Energy Agency (IAEA), Araghchi said.

As a “committed member” of the Non-Proliferation Treaty (NPT), which requires non-nuclear-weapon states not to seek or acquire nuclear weapons, Iran is “ready to cooperate with the agency in full”, Araghchi added.

But he stressed that under the treaty, Tehran also has “every right to enjoy a peaceful nuclear energy, including enrichment”.

“Enrichment is a sensitive part of our negotiations. The American team knows about our position, and we know their position. We have already exchanged our concerns, and I think a solution is achievable,” the minister noted.

Enrichment is the process of isolating and garnering a rare variant, or isotope, of uranium that can produce nuclear fission. At low levels, enriched uranium can power electric plants. If enriched to approximately 90 percent, it can be used for nuclear weapons.

US officials, including President Donald Trump, have previously suggested that Washington is seeking “zero enrichment” by Tehran.

Earlier this month, US Secretary of State Marco Rubio said any deal with Iran would need to include agreements on ballistic missiles and support for its allies in the region.

Araghchi, however, said on Sunday that Iran was “negotiating only nuclear” at the present time.

“There is no other subject,” he told CBS News, adding that he was optimistic that a deal could be reached.

The second round of nuclear talks concluded in Geneva on February 17. The US and Iran also held indirect talks in Oman earlier this month.

The Iranian delegation is working ahead of the meeting to present a draft that includes “elements which can accommodate both sides’ concerns and interests” to reach a “fast deal”, Araghchi said.

The top Iranian diplomat added the agreement would likely be “better” than the Joint Comprehensive Plan of Action (JCPOA), negotiated by former US President Barack Obama in 2015.

“There are elements that could be much better than the previous deal,” he said, without elaborating. “Right now, there is no need for too much detail. But we can agree on our nuclear programme to remain peaceful forever and at the same time, for more sanctions [to be] lifted.”

Some observers were less optimistic about the chances of striking a deal. Trita Parsi, executive vice president of the Quincy Institute, told Al Jazeera that Iran is likely to put forward a proposal that goes beyond anything they ever offered, but even that may not be enough.

“Trump has been sold a narrative by the Israelis that portrays Iran far, far weaker than it actually is. As a result, he’s adopting maximalist capitulation positions that are simply unrealistic based on how the power reality actually looks,” Parsi told Al Jazeera.

“Unless this gets corrected, even if the Iranians put forward a very far-leaning proposal that is extremely attractive to the US, Trump may still say no because he’s under the false belief that he can get something even better.”

Kim focuses on improving economic activity in opening speech at Ninth Congress of the Workers’ Party of Korea.

North Korea has kicked off a rare party congress of the ruling Workers’ Party, held once every five years, that will see the leadership in Pyongyang set major policy goals in defence, diplomacy and the economy, state media reports.

The Korean Central News Agency (KCNA) said on Friday that the Ninth Congress of the Workers’ Party of Korea (WPK) was under way, marking the start of the country’s most consequential political event since 2021.

“The Ninth Congress of the WPK opened with splendour in Pyongyang, the capital city of the revolution,” KCNA said, reporting that the high-level meeting started on Thursday and observers say it is expected to run for several days.

South Korea’s official Yonhap News Agency said the gathering will be closely followed for any signs regarding North Korea’s development of nuclear weapons or overtures towards the administrations in Seoul and the United States, which the North considers its chief foes.

Yonhap reports that North Korea’s leader, Kim Jong Un, made no mention of relations with either South Korea or the US in his opening speech to the congress on Thursday and, instead, focused on boosting the country’s economy.

“Ahead of our party are heavy and urgent tasks of advancing economic development and improving people’s livelihoods, and transforming all aspects of social life in the country as quickly as possible,” Kim said, according to KCNA.

While the true state of North Korea’s often struggling economy is hard to gauge, The Associated Press news agency reports that outside experts suggest the country has seen a gradual recovery in economic activity, helped by a post-COVID boost in trade with China and the export of weapons to help Russia in its war against Ukraine.

Several thousand North Korean troops have fought on Moscow’s side against Ukraine, and Pyongyang is believed to have exported large amounts of ammunition to help the Russian invasion of its neighbour.

North Korea’s ‘biggest enemy’

South Korea’s spy agency said last week it was monitoring the congress for any sign that Kim will officially designate his teenage daughter, Kim Ju Ae, as his potential successor, formalising her position as heir apparent in a fourth-generation succession of the Kim family as North Korea’s leaders.

At the previous party congress five years ago, Kim declared that the US was his nation’s “biggest enemy”, the AFP news agency reports, and there is deep interest in whether the North Korean leader will soften his rhetoric – or double down – at this year’s congress, particularly amid the US presidency of Donald Trump.

Trump – who met Kim in 2019 when he briefly stepped foot into North Korea to shake Kim’s hand and pose for photos – said during a tour of Asia late last year that he was “100 percent” open to meeting Kim again.

So far, Kim has demurred on Trump’s overtures to meet again.

Observers of North Korean politics are reported to be scouring satellite imagery for any signs of the vast military parades that have accompanied previous congress meetings in Pyongyang.

Such parades will be closely watched for signs of a shift in North Korea’s weapons capabilities, as the country has used previous processions to show off its newest and most advanced weapons.

Kim held a ceremony on Thursday to unveil the deployment of 50 new launch vehicles for nuclear-capable short-range missiles as the congress kicked off.

According to Yonhap, the congress brings together some 5,000 party representatives from across the country, including 200 senior officials from the WPK’s headquarters. More than 4,700 officials from regional and industrial sectors are also in attendance.

Iran launched naval drills in the Strait of Hormuz, Persian Gulf and Oman Sea, state TV reports, ahead of US-Iran nuclear talks in Geneva on Tuesday. Video shows Gen. Mohammad Pakpour, the head of Iran’s Islamic Revolutionary Guard Corps, overseeing the drills.

Foreign minister says regional powers have been ‘far more effective’ than European countries.

Iranian Foreign Minister Abbas Araghchi has derided the Munich Security Conference as a “circus”, accusing European powers of “paralysis and irrelevance” in efforts to revive nuclear negotiations with the United States.

Iranian officials were not invited to the annual security meeting in the German city.

“Sad to see the usually serious Munich Security Conference turned into the ‘Munich Circus’ when it comes to Iran,” Araghchi wrote on X on Sunday.

“The paralysis and irrelevance of the EU/E3 is displayed in the dynamics surrounding the current talks over Iran’s nuclear program. … Once a key interlocutor, Europe is now nowhere to be seen. Instead, our friends in the region [the Gulf] are far more effective and helpful than an empty-handed and peripheral E3.”

The E3 – which included France, the United Kingdom and Germany – were key players in the previous round of nuclear negotiations between world powers and Iran. That process culminated in 2015 with the Joint Comprehensive Plan of Action, a landmark agreement aimed at limiting the scope of Iran’s nuclear programme in exchange for sanctions relief.

The US under the first administration of President Donald Trump withdrew from the deal in 2018 and ramped up sanctions on Iran. Since then, the process has largely stalled. Still, the E3 maintained a role as a go-between with Tehran and Washington.

But since negotiations resumed last year, Gulf countries, such as Oman and Qatar, have taken the lead in facilitating talks between the US and Iran.

Araghchi made the remarks before leaving Tehran to lead a diplomatic and technical delegation to Geneva for a new round of nuclear talks with the US. The talks follow last week’s indirect negotiations in Oman, which is mediating the process, Iran’s Foreign Ministry said in a statement.

During his visit, Araghchi is expected to meet his Swiss and Omani counterparts, as well as the head of the International Atomic Energy Agency, Rafael Grossi, and other international officials.

Abas Aslani, a senior research fellow at the Center for Middle East Strategic Studies, said Araghchi’s comments “indicate a policy shift from the Iranian side that the E3 mechanism … is no longer a valid channel for resolution”.

“This nuclear mediation has moved from Europe to the region, and now the heavy lifting in diplomacy is done by regional players,” he said.

On Tuesday, Oman is to host talks between the US and Iran in Geneva after previous indirect negotiations in Muscat on February 6. Those talks were attended by US envoy Steve Witkoff and Trump’s son-in-law and adviser Jared Kushner.

US and Iranian officials previously held several rounds of talks in the Omani capital to discuss Iran’s nuclear programme last year. But that process was halted as Israel launched a 12-day war with Iran in June, which the US briefly joined by bombing three Iranian nuclear facilities.

The new rounds of negotiations come as tensions in the region remain high, with Trump moving more US military assets to the Middle East. On Friday, the US president said he was sending a second aircraft carrier to the region while openly talking about a change in Iran’s government.

Despite the new push for diplomacy, the two sides have maintained their positions. Iran has shown flexibility in discussing its nuclear programme, but the US wants to widen the talks to include Iran’s ballistic missiles and its support for regional armed groups – two issues that Tehran says are nonnegotiable.

Foreign Minister Sergey Lavrov did not say why he believed the US would respect the limits set out in New START.

Russia has said it will abide by limits on its nuclear weapons as set out in a lapsed arms control treaty with the United States, as long as Washington continues to do the same.

The New START agreement expired earlier this month, leaving the world’s two biggest nuclear-armed powers with no binding constraints on their strategic arsenals for the first time in more than half a century and sparking fears of a new global arms race.

In an address to parliament on Wednesday, Russian Foreign Minister Sergey Lavrov said that Moscow was in no rush to start developing and deploying more weapons – backtracking on comments made by his ministry last week that said Russia considered itself no longer bound by the treaty’s terms.

“We proceed from the fact that this moratorium, which was announced by our president, remains in effect, but only while the United States does not exceed the outlined limits,” said Lavrov.

“We have reason to believe that the United States is in no hurry to abandon these limits and that they will be observed for the foreseeable future,” he said, without explaining the basis for that assumption.

US President Donald Trump rejected an offer from Russian President Vladimir Putin to voluntarily abide by the limits set out in New START for another year, saying he wanted a “new, improved and modernised” treaty rather than an extension of the old one.

Russia has also indicated it wants to strike a new arms control agreement.

Washington is pushing for China to be included in the talks, pointing to its growing nuclear arsenal.

According to the Stockholm International Peace Research Institute (SIPRI), China’s nuclear arsenal is growing faster than that of any other country by about 100 new warheads a year since 2023.

However, Beijing refuses to negotiate with the US and Russia because it says it has only a fraction of their warhead numbers – an estimated 600, compared with about 4,000 each for Russia and the US.

As the treaty expired, Chinese Foreign Ministry spokesperson Lin Jian said that China would not be joining the bilateral arms-reduction talks.

Moscow says if China is brought into a new deal, then so too should the US’s nuclear allies, the United Kingdom and France, which have 290 and 225 warheads, respectively.

New START, first signed in Prague in 2010 by the then-presidents of the US and Russia, Barack Obama and Dmitry Medvedev, limited each side’s nuclear arsenal to 1,550 deployed strategic warheads – a reduction of nearly 30 percent from the previous limit set in 2002.

Deployed weapons or warheads are those in active service and available for rapid use as opposed to those in storage or awaiting dismantlement.

It also allowed each side to conduct on-site inspections of the other’s nuclear arsenal, although these were suspended during the COVID-19 pandemic and have not resumed since.

Russia in 2023 rejected inspections of its nuclear sites under the treaty, as tensions rose with the US over its nearly four-year war in Ukraine.

But it said it had remained committed to the quantitative limits set down.

Iran’s President Masoud Pezeshkian spoke out against intervention by ‘alien Westerners’ during a rally to mark the anniversary of the Islamic revolution. Celebrations have been taking place after weeks of US threats of military action.

Iran’s atomic energy chief says Tehran is open to diluting its highly enriched uranium if the United States ends sanctions, signalling flexibility on a key demand by the US.

Mohammad Eslami made the comments to reporters on Monday, saying the prospects of Iran diluting its 60-percent-enriched uranium, a threshold close to weapons grade, would hinge on “whether all sanctions would be lifted in return”, according to Iran’s state-run IRNA news agency.

Eslami did not specify whether Iran expected the removal of all sanctions or specifically those imposed by the US.

Diluting uranium means mixing it with blend material to reduce its enrichment level. According to the United Nations nuclear watchdog, Iran is the only state without nuclear weapons enriching uranium to 60 percent.

US President Donald Trump has repeatedly called for Iran to be subject to a total ban on enrichment, a condition unacceptable to Tehran and far less favourable than a now-defunct nuclear agreement reached with world powers in 2015.

Iran maintains it has a right to a civilian nuclear programme under the provisions of the nuclear Non-Proliferation Treaty, to which it and 190 other countries are signatories.

Eslami made his comments on uranium enrichment as the head of Iran’s Supreme National Security Council, Ali Larijani, prepares to head on Tuesday to Oman, which has been hosting mediated negotiations between the US and Iran.

Al Jazeera’s Ali Hashem, reporting from Tehran, said Larijani, one of the most senior officials in Iran’s government, is likely to convey messages related to the ongoing talks.

Trump said talks with Iran would continue this week.

Negotiations ‘very serious’

Both the US and Iran have given mixed signals about their progress in the negotiations. Iranian Foreign Minister Abbas Araghchi said Iran is “very serious in negotiations” and is eager to “achieve results”. However, he said, “There is a wall of mistrust towards the United States, which stems from America’s own behaviour.”

Iranian President Masoud Pezeshkian said the ongoing negotiations are an “important opportunity to reach a fair and balanced solution”, IRNA reported. He stressed that “Iran seeks guarantees for its nuclear rights” and the lifting of “unjust sanctions”, the agency added.

Trump, for his part, praised the latest round of talks on Friday as “very good” but continued to warn of “steep consequences” for Iran if it does not strike a deal.

“They want to make a deal as they should want to make a deal,” the US president said. “They know the consequences if they don’t.”

Before the two sides agreed to talks, Trump had repeatedly threatened Iran with a “far worse” attack than the US strikes on three Iranian nuclear facilities during June’s 12-day Israel-Iran war. He has escalated the pressure by deploying an aircraft carrier and accompanying warships to the Middle East.

Trump is expected on Wednesday to meet with visiting Israeli Prime Minister Benjamin Netanyahu, who is pushing the US to take a hardline stance in its negotiations with Iran, demanding not just concessions on its nuclear programme but also on its ballistic missiles and regional alliances.

Andreas Krieg, an associate professor in security studies at King’s College London, said the US and Iran appear to be “pivoting closer to a deal” than they were several weeks ago, even though there’s still a high risk of conflict.

“The [US] ‘armada’, as Trump calls it, is still in the area, so we still have that coercion going against the [Iranian] regime by the Americans,” Krieg told Al Jazeera. “But it seems to be fruitful in the way that the pressure works, and the Iranians have to make concessions.”

He added: “All the messaging from the Gulf countries – from Qatar, from Oman – from everyone involved, including from the Americans, has been very positive. And the Iranians’ feedback themselves was very positive.

“I think the problem that we have right now is how do we translate this momentum that we have right now on a strategic framework into the nitty-gritty of the details.”

Iran has a long history of coups, revolutions and invasions, leaving it with a complex web of economic, religious and military alliances.

On paper, it’s meant to create a balance between theocracy and democracy. In reality, only one man is truly in control.

In an exclusive interview with Al Jazeera Arabic, Iranian Foreign Minister Abbas Araghchi says Tehran is ready to reach a deal with the US that allows for peaceful nuclear enrichment, following talks in Oman. He rejects the notion that Washington should be able to dictate what range missiles Iran produces.

Washington wants Beijing to join a new nuclear weapons treaty after expiration of the New START accord between the US and Russia.

An international monitor said it has seen no evidence to support the claim by a senior United States official who accused China of carrying out a series of clandestine nuclear tests in 2020 and concealing activities that violated nuclear test ban treaties.

US Under Secretary of State for Arms Control and International Security Thomas DiNanno made the assertions about China at a United Nations disarmament conference in Geneva, Switzerland, on Friday, just days after a nuclear treaty with Russia expired.

“I can reveal that the US government is aware that China has conducted nuclear explosive tests, including preparing for tests with designated yields in the hundreds of tonnes,” DiNanno said at the conference.

China’s military “sought to conceal testing by obfuscating the nuclear explosions because it recognised these tests violate test ban commitments,” he said.

“China conducted one such yield-producing nuclear test on June 22 of 2020,” he said.

DiNanno also made his allegations on social media in a series of posts, making the case for “new architecture” in nuclear weapons control agreements following the expiration of the New START treaty with Russia this week.

“New START was signed in 2010 and its limits on warheads and launchers are no longer relevant in 2026 when one nuclear power is expanding its arsenal at a scale and pace not seen in over half a century and another continues to maintain and develop a vast range of nuclear systems unconstrained by New START’s terms,” he said.

Robert Floyd, executive secretary of the Comprehensive Nuclear-Test-Ban Treaty Organization, said in a statement on Friday that the body’s monitoring system “did not detect any event consistent with the characteristics of a nuclear weapon test explosion” at the time of the alleged Chinese test, adding that that assessment remains unchanged after further detailed analyses.

China’s ambassador on nuclear disarmament, Shen Jian, did not directly address DiNanno’s charge at the conference but said Beijing had always acted prudently and responsibly on nuclear issues while the US had “continued to distort and smear China’s national defence capabilities in its statements”.

“We firmly oppose this false narrative and reject the US’s unfounded accusations,” Shen said.

“In fact, the US’s series of negative actions in the field of nuclear arms control are the biggest source of risk to international security,” he said.

Later on social media, Shen said, “China has always honored its commitment to the moratorium on nuclear testing”.

Diplomats at the conference said the US allegations were new and concerning.

China, like the US, has signed but not ratified the Comprehensive Nuclear Test Ban Treaty (CTBT), which bans explosive nuclear tests. Russia signed and ratified it, but withdrew its ratification in ⁠2023.

US President Donald Trump has previously instructed the US military to prepare for the resumption of nuclear tests, stating that other countries are conducting them without offering details.

The US president said on October 31 that Washington would start testing nuclear weapons “on an equal basis” with Moscow and Beijing, but without elaborating or explaining what kind of nuclear testing he wanted to resume.

He has also said that he would like China to be involved in any future nuclear treaty, but authorities in Beijing have shown little interest in his proposal.

Friedrich Merz said concerns about a further escalation with Iran have dominated his trip to the Gulf region.

German Chancellor Friedrich Merz has warned of the threat of a military escalation in the Middle East before talks between Iran and the United States in Oman on Friday.

Speaking in Doha on Thursday, Merz said that fears of a new conflict had characterised his talks during his trip to the Gulf region.

“In all my conversations yesterday and today, great concern has been expressed about a further escalation in the conflict with Iran,” he said during a news conference.

Merz also urged Iran to end what he called aggression and enter into talks, saying Germany would do everything it could to de-escalate the situation and work towards regional stability.

The warning came in the run-up to a crucial scheduled meeting between officials from Tehran and Washington in Muscat.

Mediators from Qatar, Turkiye and Egypt have presented Iran and the US with a framework of key principles to be discussed in the talks, including a commitment by Iran to significantly limit its uranium enrichment, two sources familiar with the negotiations have told Al Jazeera.

Before the talks, both sides appear to be struggling to find common ground on a number of issues, including what topics will be up for discussion.

Iran says the talks must be confined to its long-running nuclear dispute with Western powers, rejecting a US demand to also discuss Tehran’s ballistic missiles, and warning that pushing issues beyond the nuclear programme could jeopardise the talks.

Reporting from Washington, DC, Al Jazeera’s Kimberly Halkett said the US is eager for the talks to follow what they see as an agreed-upon format.

“That agreed-upon format includes issues broader than what the US understands Iran is willing to discuss in this initial set of talks,” she explained.

US Secretary of State Marco Rubio said on Wednesday that talks would have to include the range of Iran’s ballistic missiles, its support for armed groups around the Middle East and its treatment of its own people, in addition to its nuclear programme.

A White House official has told Al Jazeera that Jared Kushner, US President Donald Trump’s son-in-law and a key figure in his Middle East policy negotiations, and Steve Witkoff, Trump’s special envoy, have arrived in the Qatari capital, Doha, in advance of the talks.

Halkett said that Qatar is playing an instrumental role in trying to facilitate these talks, along with other regional US partners, including Egypt.

“We understand, according to a White House official, that this is perhaps part of the reason for the visit – to try and work with Qatar in an effort to try and get Iran to expand and build upon the format of these talks.”

Pressure on Iran

The talks come as the region braces for a potential US attack on Iran after US President Donald Trump ordered forces to amass in the Arabian Sea following a violent crackdown by Iran on protesters last month.

Washington has sent thousands of troops to the Middle East, as well as an aircraft carrier, other warships, fighter jets, spy planes and air refuelling tankers.

Trump has warned that “bad things” would probably happen if a deal could not be reached, ratcheting up pressure on Iran.

This is not the first time Iranian and US officials have met in a bid to revive diplomacy between the two nations, which have not had official diplomatic relations since 1980.

In June, US and Iranian officials gathered in the Omani capital to discuss a nuclear agreement, but the process stalled as Israel launched attacks on Iran, killing several military leaders and top nuclear scientists, and targeting nuclear facilities. The US later briefly joined the war, bombing several Iranian nuclear sites.

US President Donald Trump says Iran is ‘seriously talking’ with the US and hopes that talks with Tehran will lead to a nuclear deal. Trump also reiterated that he’s sending ‘powerful ships’ to the Gulf.
