Trump says deal to end war with Iran already signed and details to be released 'pretty soon'

US President Donald Trump has said a preliminary deal to end the war with Iran has already been signed and suggested that details of the agreement are set to be published "pretty soon".

"I am very happy to say it's signed, the deal is all signed," he said during talks with French President Emmanuel Macron at the G7 summit on Monday.

Senior US officials also began giving some details about the contents of the deal, briefing that the Strait of Hormuz would re-open on Friday - the same day the deal is formally inked in Geneva.

Technical talks on Iran's nuclear programme are expected to begin this week, they said, while any sanctions relief or release of assets will depend on Iran meeting commitments under the deal.

The US officials said the agreement had been signed electronically by Trump, Vice President JD Vance and Iranian Parliament Speaker Mohammad Bagher Ghalibaf.

They also suggested more details of the pact could be released by Wednesday - although Trump said the full text of the agreement would be released "pretty soon" after Friday's ceremony.

"It's a very powerful document, and I want it to be released. So probably pretty soon," the president said.

The deal will extend a ceasefire for another 60 days, during which the sides will negotiate details of a final agreement.
