The United States and Iran have signed a memorandum of understanding to end a near four-month war, senior U.S. officials say. The officials state that the agreement is signed by U.S. President Donald Trump and Vice President JD Vance, and by Iranian parliament speaker Mohammad Bagher Qalibaf. A formal signing ceremony is expected to take place on Friday. U.S. officials also say that shipping traffic in the Strait of Hormuz will gradually ramp up after the agreement is signed, with officials describing a significant increase.

The outlets report that the memorandum follows weeks of negotiations and represents a framework to guide future U.S.-Iran relations. One report adds that while the MOU addresses steps to end the conflict, it does not immediately resolve potentially more complex issues, including discussions related to Iran’s nuclear program. The reporting also notes that the announcement has an impact on markets amid ongoing uncertainty, even as the deal is presented as a major breakthrough toward reducing the conflict’s effects. The officials speaking to the media do so on condition of anonymity in at least one account.
