U.S. President Donald Trump said on Friday (May 29, 2026) he's holding a White House Situation Room meeting with his advisors as he looks to make a “final determination” on moving forward with a deal to extend the Iran ceasefire.

Mr. Trump confirmed the high-level White House talks the day after The Associated Press and other news outlets reported that U.S. and Iranian negotiators had come to terms on a tentative agreement.

The deal would extend the fragile ceasefire by 60 days as new talks are held on Iran's disputed nuclear programme.

U.S. Vice-President J.D. Vance said on Thursday (May 28, 2026) that the sides continued to debate “a couple of language points” and he couldn't say whether Mr. Trump would approve the proposal.

Iranian Parliament Speaker Mohammad Bagher Ghalibaf on Friday (May 29, 2026), in a post on X, said that his country has “no trust in guarantees or words,” only actions, and “no step will be taken before the other side acts.”

“We do not gain concessions through talks, but through missiles. In negotiations, we only make them understand that,” wrote Mr. Ghalibaf, who was involved in negotiations in Qatar this week. He added: “The winner of any agreement is the one who is better prepared for war the day after it is signed.”

According to a U.S. official familiar with the matter, the tentative agreement would continue the ceasefire in the 3-month-old war by 60 days and start a new round of talks on Iran's nuclear programme.

Among the first issues to be negotiated during the 60-day ceasefire would be what will happen to Iran's highly enriched uranium, said the official, who was not authorised to comment publicly and spoke on condition of anonymity.

The Islamic Republic has 440.9 kilograms of uranium that is enriched up to 60% purity, a short, technical step from weapons-grade levels of 90 per cent, according to the International Atomic Energy Agency (IAEA).

Mr. Vance said that the sides were going back and forth on “a couple of issues on the nuclear stuff, the highly enriched stockpile, and also the question of enrichment.” He suggested negotiators were trying to strike general terms on the uranium issue in the tentative agreement, with the specifics to be hammered out in the ensuing talks.

Though Mr. Trump and his team said from the start of the conflict that one of their prime objectives was to ensure that Iran can never have a nuclear weapon, Mr. Vance framed the war's accomplishments as something far less definitive.

“We're in a position where we could substantially set back their nuclear programme, not just during the term of this president but over the long term,” Mr. Vance said. “That's a very very good thing for the American people.” Iran, which has long maintained its nuclear programme is peaceful, has not publicly committed to giving up the stockpile. It is believed to be buried under a trio of nuclear sites that were badly damaged by US airstrikes last year.

Nuclear analysts have said that Iran might consider China or Russia, which have close relations with Tehran, to be a potential acceptable third party to take possession of the enriched uranium. But Mr. Trump had said that he “wouldn't be comfortable” with such a plan.

The proposed memorandum makes clear that Iran will not be able to impose tolls on the Strait of Hormuz and that Iran will have to remove all mines from the vital waterway within 30 days, according to the official who spoke on condition of anonymity.

During the war, Iran has effectively closed the strait, which had been the conduit for about a fifth of the world's traded oil and natural gas. Its closure has sent oil prices skyrocketing around the world.

Iran has said it's letting some commercial vessels pass — about two dozen daily in recent days, compared with more than 100 a day before the war. But the Islamic Republic also has charged tolls for at least some ships and established a formal gatekeeper agency earlier this month, spurring a new round of U.S. sanctions this week.

Under the tentative agreement, the U.S. would gradually lift its naval blockade on Iranian ports and would also agree to relax sanctions, allowing Iran to sell more of its oil.

Yet even as word of the potential deal emerged, the U.S. Treasury Department imposed additional sanctions on the Iranian military's oil sales arm. The new penalties extend the Trump administration's economic pressure campaign on the Islamic Republic.

Iran has insisted that any deal must include an end to Israel's military operations in Lebanon against the Iranian-backed militant group Hezbollah.

Tensions deepened on Thursday (May 28, 2026) in Lebanon as Israel conducted an airstrike on a southern suburb of the capital, Beirut, and other strikes in the southern coastal city of Tyre. At least 14 people were killed across the country's south.

Since the ceasefire began about seven weeks ago, the U.S. and Iran have traded strikes and accusations of ceasefire violations. But they have not returned to full-scale hostilities and have kept negotiating.
