Iran has pledged never to produce nuclear weapons and to immediately begin reopening the Strait of Hormuz, while the US agreed to a set of financial incentives including lifting of sanctions and a reconstruction fund worth $300 billion (€258.5bn), according to a 14-point document that appears to lay out the full terms of the US-Iran framework deal.

The draft's veracity, made public by Arabic-language media in parallel, has not yet been officially confirmed by either Washington or Tehran. It also remains unclear whether the draft that circulated at G7 meetings will be the version formalised at a ceremony on Friday.

US President Donald Trump appeared irritated by the leaks, telling reporters on the margins of the G7 that "no one knows what it (the deal) is, but it will be very strong". He also warned that if Iran does not comply with the terms, the US would get "back to bombing."

Sources speaking to Euronews said that the US delegation shared the contents of the memorandum of understanding with the other G7 leaders. One diplomat described it as a roughly two-page document that could serve as the basis for a deal.

The document states in article 1 that "Iran and the US, together with their allies in the current war, declare upon the signing of this MoU an immediate and permanent end to the war on all fronts, including Lebanon, and commit that from now on they will refrain from the threat or use of force against each other."
