Leaders from the United States, Iran, and Pakistan arrived at a venue set to host talks as both nations seek a durable end to their war while disagreeing over Iran's claim that it had closed the vital Strait of Hormuz.

The U.S. and Iran had agreed to a 60-day ceasefire for the negotiations, but Tehran's Islamic Revolutionary Guard Corps on Saturday declared the Strait of Hormuz shut in response to Israeli strikes in Lebanon, although the U.S. military said commercial vessels kept operating.

Those developments could complicate the talks in which both sides want to advance an interim deal brokered by Pakistan and signed on Wednesday by Presidents Donald Trump and Masoud Pezeshkian to end an almost four-month-long war.

Vance arrived at the scenic Buergenstock resort, accessed by a narrow road snaking through leafy hills and several security checkpoints manned by armed guards, after landing at Emmen Air Base early on Sunday, accompanied by second lady Usha Vance.

Iran's foreign ministry spokesperson told state media that Iran would hold meetings with intermediaries Qatar and Pakistan earlier in the day, adding that a quadrilateral meeting between Iran, the United States, Qatar and Pakistan will also be held.
