The Latest: Vance and Iranian negotiators are in Switzerland to work on details of deal
2026-06-21T08:40:00Z
U.S. and Iranian negotiators are in Switzerland on Sunday for talks on working out key details of their interim agreement to end the Iran war.
A team led by U.S. Vice President JD Vance, including Jared Kushner and Steve Witkoff, is to meet with Iranian negotiators led by parliamentary Speaker Mohammad Bagher Qalibaf and Foreign Minister Abbas Araghchi.
Pakistani envoys are also in place, as well as Qatari mediators, for the technical-level discussions to end the conflict that began in late February.
Vance said he was optimistic about making progress in talks about Iran’s nuclear program and a ceasefire in southern Lebanon.
On the eve of the talks, Tehran announced it has closed the Strait of Hormuz again over Israel’s ongoing military campaign in Lebanon. The interim deal between the U.S. and Iran is meant to stop fighting on all fronts, including Lebanon, as well as calling for billions of dollars of Iran’s assets to be unfrozen.
U.S. President Donald Trump has threatened to impose American tolls in the strait if a final deal with Iran isn’t reached in 60 days. The interim agreement calls for toll-free travel for 60 days in the waterway that is vital for the world’s oil supply.
Here is the latest:
The head of the UN nuclear watchdog is also at the scene of the talks
Rafael Grossi, chief of the U.N. nuclear watchdog — the International Atomic Energy Agency — met with Swiss Foreign Minister Ignazio Cassis on the sidelines of the gathering at the picturesque mountainside resort near Lake Lucerne on Sunday morning.
The agency had monitored the 2015 nuclear deal negotiated between the U.S. and Iran under the Obama administration.
Trump in 2018 withdrew the U.S. from that agreement.
Talks in Switzerland will focus on the Israel-Hezbollah war, Iran says
Iran’s Foreign Ministry spokesman Esmail Baghaei says Tehran will mainly focus during the talks on Sunday on the ongoing fighting in Lebanon.
Tehran insists that the deal’s implementation start with a cessation of all fighting — including between Israel and Hezbollah.
Baghaei said the U.S. “has been unable or unwilling” to hold Israel to the ceasefire.
Iran will meet in the morning with Pakistani and Qatari mediators, and in the afternoon, there will be a four-way meeting including the U.S. negotiating team. There is currently only one day of negotiations planned, Baghaei told the state news agency.
“The implementation of any document is more important than its signing,” Baghaei also said Sunday.

Iran’s president has said that Iran will maintain its right to a nuclear program.
“What is certain is that we will never back down from the right to enrich uranium, and the other side is also forced to accept it,” Masoud Pezeshkian said on Sunday, according to state media.
A temporary lull in Israeli strikes in Lebanon
As the U.S.-Iran talks were to kick off in Switzerland, a ceasefire appears to be holding in Lebanon, a lull that came after another day of heavy fighting.
Lebanon’s Health Ministry reported over 50 killed in Israeli strikes since the deal was signed on Thursday. Five Israeli soldiers were also killed.
Israel says it targeted Hezbollah infrastructure on Saturday, including a tunnel network in the southern Lebanese town of Kfar Tebnit.
But by Sunday morning, residents in southern Lebanon reported a lull in Israeli strikes. There also were no reports of Hezbollah fire from the Israeli side.
Israel’s military has received instructions to uphold the ceasefire, and said it is only acting defensively, according to an Israeli military official who spoke on condition of anonymity in line with military guidelines.

Pakistani mediators also in place in Switzerland
Pakistani Prime Minister Shehbaz Sharif and army chief Field Marshal Asim Munir are also in Switzerland for the high-level U.S.-Iran talks, the prime minister’s office said without providing further details.
The technical-level talks at Bürgenstock Resort near the Swiss city of Lucerne are being held after Sharif dispatched his special envoy, Interior Minister Mohsin Naqvi, to Tehran to persuade Iranian authorities to send a delegation to Switzerland. The meeting was originally scheduled for Friday but was delayed because of concerns raised by Iran.
Naqvi later informed Islamabad that Iran was willing to attend the talks. Pakistan subsequently conveyed the development to Washington.
Strait of Hormuz is once again a challenge
The strait has emerged as a key focus, with Iran’s joint military command saying on Saturday that it was closed again because of the U.S. “clear breach of its commitments” by failing to end the war. The interim deal is meant to stop fighting on all fronts, including in Lebanon where Israeli forces are battling the militant Hezbollah group.
The U.S. disputed Iran’s announcement, with the U.S. Central Command saying that traffic continues to flow and that 55 merchant ships transited on Saturday with more than 17 million barrels of oil.
Ships began transiting after the interim U.S.-Iran agreement was signed last week. The U.S. lifted its blockade of Iran’s ports and now allows Tehran to sell its oil freely — terms that have left some in U.S. Congress asking whether the war was worth it.
The interim deal signed by Trump and Iranian President Masoud Pezeshkian gives negotiators 60 days to reach a nuclear agreement, but the time can be extended.
