What is the main purpose of the US-Iran talks in Switzerland, and who are the key participants?

The main purpose of the US-Iran talks in Switzerland is to establish a permanent ceasefire and begin negotiations on the long-running dispute over Iran’s nuclear capabilities, building on a recently signed memorandum of understanding. Key participants include US Vice President JD Vance; Iran’s Parliament Speaker Mohammad Bagher Ghalibaf, Foreign Minister Abbas Araghchi, and Central Bank Governor Abdolnaser Hemmati; and mediators Pakistani Prime Minister Shehbaz Sharif and military chief Asim Munir.

How has recent regional conflict — particularly between Israel and Hezbollah — affected the timing and credibility of the US-Iran talks?

Separate clashes in southern Lebanon between Israeli forces and Iran-backed Hezbollah delayed the start of the talks, and Iran subsequently claimed a ceasefire violation, prompting its renewed threat to close the Strait of Hormuz; Tehran also asserts that the US bears 'direct responsibility' for Israel’s military actions, complicating negotiations and highlighting how Israel’s involvement — though it is not a party to the deal — continues to undermine diplomatic progress.
