Fresh US-Iran rift surfaces as Trump claims nuclear inspection deal and Tehran denies it

US President Donald Trump on Tuesday repeated his claim that Iran had “fully and completely agreed” to long-term nuclear inspections as part of ongoing negotiations with Washington, even after push back from Tehran.

In a post on his Truth Social platform, Trump said Iran had agreed to the “highest level Nuclear inspections long into the future” and said that, based on that and other concessions by Tehran, he had agreed to allow the Strait of Hormuz to remain open without a US naval blockade.

"However, all ships are remaining in place should it be necessary to reinstitute the Blockade, which seems, at this point, highly unlikely," the US president said.

He also said US sanctions relief and money being released to Iran would be placed in escrow controlled by Washington and used only to buy food and medical supplies from the United States.

“Talks are going well!” Trump wrote.

Earlier in the day, Iranian President Masoud Pezeshkian appeared to reject Trump administration claims that Tehran had accepted new terms on nuclear monitoring.

In a post on X earlier Tuesday, Pezeshkian said progress in the negotiations depended on “full commitment to the agreed obligations and their precise implementation,” adding that “statements outside the agreed text do not help advance the negotiations.”

His remarks were in apparent reference to comments by Vice President JD Vance, who said after the first round of talks in Switzerland that Iran had agreed to allow inspectors from the International Atomic Energy Agency back into the country and that discussions with the UN nuclear watchdog could begin “as soon as today.”

Trump had also said earlier on social media that Iran “will agree to have Major Weapons Inspections.”

Iran’s Foreign Ministry, however, denied that any new inspection arrangement had been struck.

In an interview with the state-run IRNA news agency, Iran's foreign ministry spokesperson Esmail Baqai said Tehran had made “no new commitments” on nuclear inspectors.

He said any cooperation with UN inspectors would continue under procedures already set by Iran’s parliament and the Supreme National Security Council.

In a joint statement released Monday, mediators Qatar and Pakistan said the United States and Iran had agreed during talks at the Swiss resort of Bürgenstock to a “roadmap towards reaching a final deal within 60 days.”

The mediators said the two sides agreed to establish a high-level committee to provide political oversight to the negotiations, while chief negotiators would lead working groups on Iran’s nuclear program, sanctions and a monitoring and dispute-resolution mechanism.

The statement also said the parties had opened a communication line to prevent incidents and miscommunication during the 60-day negotiation period and to help ensure safe passage for commercial vessels through the Strait of Hormuz.

It said the sides also agreed to create a deconfliction cell involving the United States, Iran and Lebanon to help uphold the halt in military operations in Lebanon under an earlier memorandum.

The joint statement did not mention any specific agreement on nuclear inspections.
