Trump says US-Iran deal is already signed

US President Donald Trump says a preliminary deal with Iran has already been signed, before a formal ceremony in Geneva on Friday.

The agreement is meant to ease months of fighting and reopen the Strait of Hormuz, one of the world’s most important oil routes.

The full text has not been published.

US officials say the document was signed electronically by Trump, Vice-President JD Vance and Iran’s parliamentary speaker.

Washington says the deal will start talks on a wider agreement over Iran’s nuclear programme.

Iran says the agreement is only a first step.

Israel has warned it will not accept any deal that allows Iran to obtain nuclear weapons.
