Washington DC - US President Donald Trump, Vice President JD Vance, and Iranian parliament speaker Mohammad Bagher Ghalibaf electronically signed a deal to end the Middle East war, a senior US administration official said Monday.

"The president wanted to sign it personally because he wanted to show his... dedication to bring this through to a successful resolution," the official, speaking on condition of anonymity, told reporters in a call.

Other US officials noted on Monday that ships will move toll-free through the Strait of Hormuz under the Iran peace deal, and insisted that Tehran would have to fulfill its commitments before getting any economic benefits.

They included a possible $300 billion reconstruction fund for the war-battered country.

The release of funds will be "tied to performance," a senior Trump administration official said in a call with reporters.

Technical talks led by Vance will begin this week before the deal is formally signed on Friday in a ceremony that is expected to be held in Geneva, Switzerland.

Vance, Trump's son-in-law Jared Kushner, and Middle East Special Envoy Steve Witkoff will attend the signing, the officials said.
