United States president Donald Trump.
Donald Trump says both he and JD Vance have signed a memorandum of understanding (MOU) to end the war the United States and Israel launched on Iran more than 100 days ago.
The US president said he signed a "great deal" with Iran and promised the Strait of Hormuz would soon be opened.
The speaker of the Iranian parliament, and former commander of the Islamic Revolutionary Guard Corps (IRGC), Mohammad Baqer Qalibaf, is believed to have signed on behalf of the regime.
