US, Iran set for talks as Lebanon conflict threatens deal
The first round of negotiations between the United States and Iran since the two sides signed a preliminary agreement to halt their war was due to begin in Switzerland on Sunday, with the conflict in Lebanon threatening the deal.
Washington and Tehran signed a memorandum of understanding earlier in June to extend the ceasefire in the Middle East war, which began in late February with U.S.-Israeli strikes on Iran, and enable negotiations on a broader deal.
As part of the agreement, the Israel-Hezbollah war in Lebanon was due to stop, but Iran said it would close the Strait of Hormuz again because of Israeli attacks. There were no reports of fresh strikes in Lebanon since Saturday evening.
U.S. Vice President JD Vance arrived at the Swiss mountainside resort of Burgenstock early on Sunday to meet Iranian negotiators for the second time since the months-long conflict sowed chaos across the Middle East and rattled the global economy.
