US Vice President JD Vance arrived in Switzerland on Sunday for what he has said would likely be a couple of days of peace talks with Iranian officials.
Vance and his wife arrived at Emmen Air Base in Switzerland at 5:59 am (0359 GMT), a vice presidential spokesperson said.
Vance, in an interview with Fox News, said he was confident the ceasefire would hold and that he had seen no evidence that the Strait of Hormuz was closed.
"I think we're going to hopefully make progress on the nuclear issue, make progress on the Lebanon ceasefire issue," he said.
High-level officials from Iran have already arrived in Switzerland for peace talks, the country's state media reported.
Pakistani Prime Minister Shehbaz Sharif and the army chief, Field Marshal Syed Asim Munir, will attend this weekend's sessions, the country's ministry of foreign affairs said.
