Talks set to take place on Friday between the ⁠United States ⁠and Iran on implementing the 14-point agreement to end their war have been cancelled, Switzerland’s foreign ministry has announced.

The announcement came after a White House spokesperson said overnight that U.S. Vice President JD Vance had pulled out ‌of ⁠a planned trip to meet Iranian negotiators in Switzerland on Friday to ⁠begin talks on implementing an agreement struck between Tehran and ⁠Washington to end the war.

The team led by Vance had been ready to leave but was postponing, the White House said, citing difficult logistics for negotiations.

The announcement followed a report from Al-Mayadeen, a pan-Arab satellite channel that is politically allied with the Iranian-backed Lebanese militant group Hezbollah, that Iran was delaying sending its delegation to Switzerland over Israel’s ongoing military campaign in Lebanon, according to AP.
