Nuclear Energy

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.”

Few places in Ukraine have been spared from the impact of the Ukraine war, including the radioactive exclusion zone around the Chernobyl nuclear plant. Al Jazeera’s Nils Adler has been seeing how the site of the world’s worst nuclear disaster has been affected by the war.

Iran’s top diplomat says he hopes to ‘achieve a fair and equitable deal’ before high-stakes talks are held on Tuesday.

Iranian Foreign Minister Abbas Araghchi has arrived in Geneva for high-stakes second round of nuclear talks with the United States aimed at reducing tensions and avert a new military confrontation that Iran’s Supreme Leader Ayatollah Ali Khamenei has warned could turn into a regional conflict.

“I am in Geneva with real ideas to achieve a fair and equitable deal,” Araghchi wrote on X on Monday. “What is not on the table: submission before threats.”

Iran and the US renewed negotiations earlier this month to tackle their ⁠decades-long dispute over Tehran’s nuclear programme as US deploys warships, including a second aircraft carrier, to the region as mediators work to prevent a war.

Araghchi met with Rafael Grossi, the head of the International Atomic Energy Agency (IAEA), on Monday, after saying his team nuclear experts for a “deep technical discussion”.

The United Nations nuclear watchdog has been calling for access to Iran’s main nuclear facilities that were bombed by the US and Israel during the 12-day war in June. Tehran has said there might be a risk of radiation, so an official protocol is required to carry out the unprecedented task of inspecting highly enriched uranium ostensibly buried under the rubble.

Speaking to state-run IRNA news agency on Monday, foreign ministry spokesman Esmail Baghaei said the IAEA will play “an important role” in upcoming mediated talks between Iran and the US. But he also renewed Tehran’s criticism of Grossi for the director’s refusal to condemn military strikes on Iranian nuclear sites that are protected under agency safeguards as part of the Non-Proliferation Treaty (NPT).

Araghchi also said he would meet his Omani counterpart, Badr bin Hamad al-Busaidi, who mediated the first round of talks between Iran and the US since the war earlier this month.

Iran has repeatedly emphasised that it will not agree to Washington’s demand for zero nuclear enrichment, and considers its missile programme a “red line” that cannot be negotiated.

Meanwhile, the US continues to build up its military presence in the region, with President Donald Trump saying a change of power in Iran “would be the best thing that could happen” and sending in a second aircraft carrier.

Trump is again likely to send his special envoy Steve Witkoff and his son-in-law Jared Kushner to represent the White House in the Geneva talks. Brad Cooper, the most senior US military commander in the region, had unexpectedly joined the US delegation during the Muscat talks on February 6.

The talks also come over a month after Iran’s deadly crackdown against nationwide protests, with Iranian officials claiming “terrorists” and “rioters” armed and funded by the US and Israel were behind the unrest.

The UN and international human rights organisations have blamed Iranian authorities for the widespread use of lethal force against peaceful protesters, which killed thousands, mainly on the nights of January 8 and 9.

But the hardliners in Tehran are more concerned about any potential concessions that could be given during upcoming talks with the US.

Addressing an open session on Monday, one of the most hardline lawmakers in Iran’s parliament cautioned security chief Ali Larijani against giving inspection access to the IAEA befire ensuring Iran’s territorial integrity, the security of nuclear sites and scientists, and use of peaceful nuclear energy for civilian purposes under the NPT.

“When US warships have opened their arms to embrace Iranian missiles, US bases have opened arms to take our missiles, and the homes of Zionist military personnel are anticipating the sound of the air raid sirens, it is obvious that such conditions cannot be met at the moment,” said Hamid Rasaei, a cleric close to the hardline Paydari (Steadfastness) faction.

In the other diplomatic track pursued in Switzerland on Tuesday, officials will be discussing ways of ending the Ukraine war, which is approaching the end of its fourth year after Russia’s full-scale invasion in 2022.

But no immediate breakthrough appears in sight, with Ukrainian President Volodymyr Zelenskyy telling the annual Munich Security Conference on Saturday that Kyiv has “too often” been asked to make concessions.

Trump says he believes negotiations with Iran will be ‘successful’ as he confirms USS Gerald R Ford deployment.

President Donald Trump says that he is sending a second aircraft carrier to the Middle East as the United States increases pressure on Iran over its nuclear and ballistic missile programmes.

Speaking at the White House on Friday, Trump confirmed that the USS Gerald R Ford would be leaving the Caribbean for the Middle East “very soon” as tensions remain high following indirect talks in Oman last week.

“If we need it, we’ll have it ready, a very big force,” said Trump, adding that he believed negotiations would be “successful” while warning it would be a “bad day for Iran” if the country failed to make a deal.

Later, Trump said a change of government in Iran would be the “best thing that could happen”.

“For 47 years, they’ve been talking and talking and talking. In the meantime, we’ve lost a lot of lives,” he said, in an apparent reference to Tehran’s crackdown on recent antigovernment protests that left thousands dead.

The imminent departure of the Gerald R Ford is part of an ongoing buildup of military hardware in the region, with the Abraham Lincoln carrier, several guided-missile destroyers, fighter jets and surveillance aircraft sent in recent weeks.

Trump’s comments come days after he met Israeli Prime Minister Benjamin Netanyahu in Washington, with the latter saying a “good deal” was expected while voicing reservations if any agreement did not also curb Iran’s ballistic missile programme. Tehran has publicly rejected US pressure to discuss the missiles.

Netanyahu has repeatedly called for further military action since Israel’s 12-day war against Iran in June, which the US briefly joined by attacking three Iranian nuclear sites, in a military operation dubbed “Midnight Hammer”.

Trump at the time said the US attacks had “totally obliterated” the nuclear facilities.

The indirect US-Iran talks were the first to be held since the June conflict, which halted previous rounds of negotiations between Tehran and Washington over potentially replacing the Joint Comprehensive Plan of Action (JCPOA), which Trump ditched during his first term in office.

Risk of escalation

The JCPOA, a deal reached between Iran, the US and several European powers, saw Tehran curtail its nuclear programme in exchange for sanctions relief.

Following Trump’s unilateral withdrawal in 2018, Tehran subsequently began enriching uranium beyond the limits set out in the agreement, though it has repeatedly denied Western claims it is seeking a nuclear weapon.

Upon taking office for a second time in January, Trump initially sought a new nuclear deal with Iran, but soon adopted a zero-enrichment policy long dismissed by Iranian negotiators as a non-starter.

As the latest attempts at negotiations continue, United Nations nuclear watchdog chief Rafael Grossi has had trouble getting Iran to agree on inspections of sites targeted in the 12-day war.

Grossi, who heads the International Atomic Energy Agency, told the Munich Security Conference that inspectors had returned to Iran after the 12-day war but had not been able to visit any of the sites targeted.

Grossi said dialogue with Iran since the inspectors’ return last year had been “imperfect and complicated and extremely difficult, but it’s there”.

The US president’s comments on Friday confirm his earlier indication that he was considering sending the Gerald R Ford, which has a nuclear reactor on board and can hold more than 75 military aircraft, to the region.

Gulf Arab nations have warned any attack could escalate into another regional conflict in a region still reeling from Israel’s genocidal war on Gaza.

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.”

Tehran, Iran – Iran’s President Masoud Pezeshkian has called on the United States to respect his country as the two nations look ahead to another round of nuclear negotiations next week following mediated discussions in Oman.

“Our reasoning on the nuclear issue is based on rights stipulated in the Non-Proliferation Treaty,” he wrote in a post on X on Sunday. “The Iranian nation has always responded to respect with respect, but cannot withstand the language of force”.

Pezeshkian described the indirect talks held in Oman on Friday as a “step forward” and said his administration favours dialogue.

Iranian officials are highlighting sovereignty and independence and are signalling eagerness for nuclear-only negotiations, while rejecting a military build-up in the region by the US.

Speaking at a forum hosted by the Ministry of Foreign Affairs in Tehran, the country’s chief diplomat Abbas Araghchi pointed out that the Islamic Republic has always emphasised independence since overthrowing US-backed Mohammad Reza Shah Pahlavi in a 1979 revolution.

“Before the revolution, the people did not believe their establishment to have possessed true independence,” Araghchi said.

The messaging comes as the anniversary of the revolution approaches on Wednesday, when state-organised demonstrations have been planned across the country. Iranian authorities have in previous years exhibited military equipment, including ballistic missiles, during the rallies.

Araghchi said during the event in the capital that Iran is unwilling to forego nuclear enrichment for civilian use even if it leads to more military attacks by the US and Israel, “because no one has the right to tell us what we must have and must not have”.

However, the diplomat added that he told US envoys Steve Witkoff and Jared Kushner in Muscat on Friday that “there is no way but negotiations”. He said China and Russia have also been informed of the content of the talks.

“Being afraid is lethal poison in this situation,” Araghchi said about Washington amassing what US President Donald Trump has called a “beautiful armada” near Iran’s waters.

‘Push the region back years’

Iran’s top military commander on Sunday issued a new warning that the entire region will be engulfed in conflict if Iran is attacked.

“While being prepared, we genuinely have no desire to see the outbreak of a regional war,” Major General Abdolrahim Mousavi told a gathering of air force and air defence commanders and personnel.

“Even though aggressors will be the target of the flames of regional war, this will push back the advancement and development of the region by years, and its repercussions will be borne by the warmongers in the US and the Zionist regime,” he said in reference to Israel.

According to Mousavi, Iran “has the necessary power and preparedness for a long-term war with the US”.

But many average Iranians are left in limbo without much hope that the talks with the US will lead to results, including for the country’s heavily declining economy.

“I was 20 when the first negotiations with the West over Iran’s nuclear programme were held about 23 years ago,” Saman, who works at a small private investment firm in Tehran, told Al Jazeera.

“Our best years are behind us. But it’s even more sad to think that some of the youth who were born at the start of the negotiations were killed on the streets during the protests last month with many hopes and dreams.”

‘They never returned’

Iran is witnessing tense time and threats of a massive US military strike. But the Islamic Republic has not overcome anti-government protests that shook the nation, denouncing the collapse of the national currency, soaring prices and economic hardship.

State television continues to broadcast confessions of Iranians arrested during the nationwide protests, many of whom are accused by the state of working in line with the interests of foreign powers.

In a report aired late on Saturday, a woman and multiple men with blurred-out faces and in handcuffs could be seen saying they were led by a man who allegedly received weapons and money from Mossad operatives in neighbouring Iraq’s Erbil.

“He only wanted more people to die; he shot at everyone,” one of the confessing men said about what allegedly transpired during unrest in the Tehranpars district in the eastern part of the capital, backing the state’s claim that “terrorists” are responsible for all deaths.

Iranian authorities have accused the US, Israel and European countries of instigating the protests.

But international human rights organisations and foreign-based opposition groups accuse state forces of being behind the unprecedented killings during the protests, which were carried out mostly on the nights of January 8 and 9.

The Iranian government claims 3,117 people were killed, but the US-based Human Rights Activists News Agency (HRANA) says it has documented nearly 7,000 fatalities and is investigating more than 11,600 cases. The United Nations special rapporteur on Iran, Mati Sato, said more than 20,000 may have been killed as information trickles out despite heavy internet filtering.

Al Jazeera cannot independently verify these figures.

Amid numerous reports that dozens of medical staff were arrested for treating wounded protesters and remain incarcerated in harsh conditions, Iran’s judiciary issued a rejection of the allegations late Saturday. It claimed that only “a limited number of medical personnel were arrested for participating in riots and playing a role in the field”.

A large number of schoolchildren and university students were also reportedly among tens of thousands arrested during and in the aftermath of the nationwide protests. The Ministry of Education claimed last week that it did not know how many schoolchildren were arrested, but could confirm that all have since been released.

The Coordinating Council of Iranian Teachers’ Trade Associations on Sunday released the four-minute video below, titled “200 empty school desks”, which shows the schoolchildren and teenagers confirmed killed during the protests. Many were accompanied by their parents when killed.

One month after the killings, countless families are left grieving and continue to release videos commemorating their loved ones online.

A message on Instagram calling on the international community to keep talking about the people of Iran has now been shared more than 1.5 million times.

“One month ago today, thousands woke up and ate breakfast for the last time without knowing it, and kissed their mother for the last time without knowing it,” the message reads. “They lived for the last time and never returned.”

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.

Iranian Foreign Minister Abbas Araghchi says he hopes talks with the United States will resume soon, while US President Donald Trump pledged another round of negotiations next week following mediated discussions in Oman.

Araghchi told Al Jazeera on Saturday that Iran’s missile programme was “never negotiable” in Friday’s talks, and warned Tehran would target US military bases in the Middle East if the US attacks Iranian territory.

He added that despite the negotiations in Muscat being indirect, “an opportunity arose to shake hands with the American delegation”. The talks were “a good start“, but he insisted “there is a long way to go to build trust”.

Iranians in the capital, Tehran, however, seemed less positive.

“In my opinion, like previous times, negotiations will end without results because both sides are sticking to their own positions and not willing to back down,” a woman who asked to remain anonymous told Al Jazeera.

Abdullah al-Shayji, a US foreign policy expert at Kuwait University, said he hopes for a new deal between the two foes but is not feeling optimistic.

“There is a strong position” from the US and “being provoked by” Israel to “clamp down on the Iranians because they feel that Iran is at its weakest point” so that it will be easy to extract concessions from it, especially after last month’s antigovernment demonstrations, al-Shayji said from the Al Jazeera Forum in Qatar’s capital Doha.

‘Inalienable right’

Despite calling the talks “very good” on Friday, Trump signed an executive order effective from Saturday that called for the “imposition of tariffs” on countries still doing business with Iran.

The US also announced new sanctions against numerous shipping entities and vessels aimed at curbing Iran’s oil exports.

More than one-quarter of Iran’s trade is with China, including $18bn in imports and $14.5bn in exports in 2024, according to World Trade Organization data.

Nuclear enrichment is Iran’s “inalienable right and must continue”, Araghchi said, adding, “We are ready to reach a reassuring agreement on enrichment. The Iranian nuclear case will only be resolved through negotiations.”

Iran’s missile programme is non-negotiable because it relates to a “defence issue”, he said.

Washington has sought to address Iran’s ballistic missile programme and its support for armed groups in the region – issues that Israel has pushed to include in the talks, according to media reports.

Tehran has repeatedly rejected expanding the scope of the negotiations beyond the nuclear issue.

“The Iranians are vehemently opposed to any concessions,” said al-Shayji, as is the US, which makes it extremely hard for countries leading mediation efforts to “get them closer together”.

Friday’s negotiations were the first since nuclear talks between Iran and the US collapsed last year following Israel’s unprecedented bombing campaign against Iran, which triggered a 12-day war.

Following widespread antigovernment protests in Iran last month, Trump ramped up threats against the country, deploying the USS Abraham Lincoln to the Middle East.

‘Peace through strength’

Trump’s lead negotiators in Oman, special envoy Steve Witkoff and presidential adviser Jared Kushner, visited the aircraft carrier stationed in the Arabian Sea on Saturday.

In a social media post, Witkoff said the aircraft carrier and its strike group are “keeping us safe and upholding President Trump’s message of peace through strength.”

Witkoff said he spoke with the pilot who downed an Iranian drone that approached the carrier “without clear intent” on Tuesday.

“Proud to stand with the men and women who defend our interests, deter our adversaries, and show the world what American readiness and resolve look like, on watch every day,” said Witkoff.

While Trump has sought to use the aircraft carrier’s deployment as a means to exert pressure on Iran, al-Shayji said this cannot be a long-term strategy.

“He [Trump] can’t keep his forces at alert stage for too long. This would really discredit Trump’s administration regarding being very harsh and hard-liners on Iran,” he said.

Israeli Prime Minister Benjamin Netanyahu is set to meet Trump on Wednesday to discuss the Iran talks, his office said in a statement.

Netanyahu “believes any negotiations must include limitations on ballistic missiles and a halting of the support for the Iranian axis”, it said, referring to Iran’s allies in the region.

During the 12-day war, US warplanes bombed Iranian nuclear sites.

Araghchi expressed hope that Washington would refrain from “threats and pressure” so “the talks can continue”.

US and Iranian officials are holding talks in Muscat amid escalating tensions and a US military buildup in the Gulf.

Iran’s foreign minister says missile programme not up for negotiation as Trump says he’s sending more ships to the region.

Iran’s foreign minister says the country is ready for “fair and equitable” talks with the United States amid soaring tensions, as US President Donald Trump refused to rule out taking military action against Tehran.

On a visit to Turkiye on Friday, Iranian Foreign Minister Abbas Araghchi told reporters that, “Iran has no problem with negotiations, but negotiations cannot take place under the shadow of threats”.

“I should also state unequivocally that Iran’s defensive and missile capabilities – and Iran’s missiles – will never be the subject of any negotiations,” Araghchi said during a news conference alongside his Turkish counterpart, Hakan Fidan.

“The security of the Iranian people is no one else’s business, and we will preserve and expand our defensive capabilities to whatever extent is necessary to defend the country.”

Tensions have been rising for weeks between Tehran and Washington amid Trump’s repeated threats to attack Iran over a recent crackdown on antigovernment protests and his push to curtail the Iranian nuclear programme.

Earlier this week, the US president said a “massive armada” – led by the USS Abraham Lincoln aircraft carrier – was moving towards Iran and was ready to use “violence, if necessary” if Iranian leaders did not agree to negotiate a nuclear deal.

Speaking to reporters at the White House on Friday, Trump said his administration was sending “a larger number of ships” to Iran.

“And hopefully we’ll make a deal,” he said. “If we do make a deal, that’s good. If we don’t make a deal, we’ll see what happens.”

Reporting from Washington, DC, Al Jazeera’s Kimberly Halkett noted that Trump said he gave Iran a deadline, but “only Iran knows what that deadline is”.

“So he’s left the world in waiting, trying to determine what the next steps will be,” Halkett said.

Trump, who in 2018 unilaterally withdrew from a previous deal that saw Iran agree to curb its nuclear programme in exchange for a lifting of international sanctions, has been pressuring Iran to halt all uranium enrichment.

Washington has accused Tehran of seeking a nuclear weapon – a claim Iranian leaders have repeatedly denied.

Amid the latest tensions, senior officials in Tehran have repeatedly said they are open to negotiations, but only once Trump ends his military threats against the country.

They also have stressed that Iran’s armed forces are ready to respond if attacked.

Meanwhile, regional allies including Turkiye, the United Arab Emirates and Saudi Arabia have been engaging in diplomatic efforts to try to prevent a military confrontation between Washington and Tehran.

Turkish President Recep Tayyip Erdogan earlier on Friday told his Iranian counterpart Masoud Pezeshkian in a call that Ankara was ready to play a “facilitator” role between the two sides.

Fidan, the Turkish foreign minister, also said he had long discussions on the issue with US special envoy Steve Witkoff on Thursday and would keep lines open with Washington.

Speaking alongside Araghchi on Friday, Fidan said US-Iran nuclear negotiations must restart and would pave the way to lifting sanctions on Iran.

“We call the parties to the negotiating table” to address the issues “one by one”, he said.

Russian attacks on Ukraine’s electrical substations could cut power to nuclear plants, increasing risks of meltdown.

The United Nations nuclear watchdog has held a special session on Ukraine amid growing fears that Russian attacks on its energy facilities could trigger a nuclear accident.

Rafael Grossi, director-general of the International Atomic Energy Agency (IAEA), said at the start of Friday’s extraordinary board meeting in Vienna that the war in Ukraine posed “the world’s biggest threat to nuclear safety”.

The meeting was held as an IAEA expert mission conducted a weeks-long inspection of 10 electrical substations that Grossi described as “crucial to nuclear safety”.

Although nuclear power plants generate power themselves, they rely on an uninterrupted supply of external power from electrical substations to maintain reactor cooling.

Ukraine has four nuclear power plants, three of them under Kyiv’s control, with the fourth and biggest in Zaporizhzhia occupied by Russian forces since the early days of their full-scale invasion in 2022.

Moscow and Kyiv have repeatedly accused each other of risking a nuclear catastrophe by attacking the Zaporizhzhia site.

The plant’s six reactors have been shut down since the occupation, but the site still needs electricity to maintain its cooling and security systems.

Earlier this month, Russia and Ukraine paused local hostilities to allow repairs on the last remaining backup power line supplying the plant, which was damaged by military activity in January.

Ukraine is also home to the former Chornobyl plant, the site of the world’s worst nuclear accident in 1986. The site’s protective shield containing radioactive material was damaged last year in a drone strike allegedly carried out by Russia.

Status of energy ceasefire unclear

The four-hour IAEA meeting, which aimed to increase pressure on Russia, was called at the request of the Netherlands, with the support of at least 11 other countries.

Russia’s “ongoing and daily” attacks against Ukraine’s energy infrastructure in recent weeks have caused significant damage, Netherlands’ Ambassador Peter Potman told the board.

“Not only does this leave millions of Ukrainians in the cold and dark during a very harsh winter, but it is also … bringing the prospect of a nuclear accident to the very precipice of becoming a reality,” he said.

Ukraine’s ambassador, Yuriy Vitrenko, said it was “high time” for the IAEA to “shine an additional spotlight on the threat to nuclear safety and security in Europe” caused by Russia’s “systematic and deliberate” attacks.

Russian Ambassador Mikhail Ulyanov dismissed the board’s gathering as “absolutely politically motivated”, adding there was “no real need to hold such a meeting today”.

The status of a current weeklong moratorium on attacks targeting energy infrastructure is currently unclear.

United States President Donald Trump said Thursday that Russia had agreed to his request not to attack Ukraine’s energy infrastructure for a week.

On Friday, Ukrainian President Volodymyr Zelenskyy confirmed that neither Moscow nor Kyiv had conducted strikes ⁠on energy targets from Thursday night onwards.

However, Kremlin spokesman Dmitry Peskov later suggested the pause in attacks would end on Sunday.
