US and Iran announce peace deal on Trump's 80th birthday; Strait of Hormuz to reopen, formal signing set for Friday in Switzerland
On 15 June 2025, the United States and Iran announced a peace agreement ending more than 100 days of armed conflict that began when the US and Israel launched airstrikes on Iran on 28 February. President Trump announced the deal via Truth Social, authorising the reopening of the Strait of Hormuz and lifting the US naval blockade of Iranian ports. Pakistan's Prime Minister Shehbaz Sharif, who mediated negotiations alongside Qatar, confirmed the deal and announced a formal signing ceremony for Friday 19 June in Switzerland. Iran's deputy foreign minister confirmed the agreement. Oil prices fell sharply on the news. Key details remain undisclosed publicly, including the fate of Iran's nuclear programme, with major issues deferred to a 60-day ceasefire negotiation period. The announcement coincided with Trump's 80th birthday and a UFC event held at the White House.
