US-Iran talks begin in Switzerland as Tehran says it closed Strait of Hormuz

June 21, 2026

Direct negotiations between the United States and Iran have commenced in Switzerland following Iran's announcement that it closed the Strait of Hormuz in response to Israeli military operations in southern Lebanon. The talks involve high-level delegations, with US Vice-President JD Vance meeting with Iranian officials and Pakistani mediators who previously facilitated negotiations between the two nations. The discussions aim to address nuclear concerns and implement a recently signed initial agreement to end regional conflict, though ongoing clashes between Israel and Hezbollah complicate the situation.

Who is affected

Iranian government officials (parliamentary speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi)
US Vice-President JD Vance and the US delegation
Pakistani mediators (PM Shehbaz Sharif and army chief Asim Munir)
Lebanese civilians (at least 47 killed in recent strikes, 4,057 total deaths since March 2)
Israeli Defense Forces soldiers (four killed)
Hezbollah militia members (dozens killed according to IDF)
Ships and maritime traffic using the Strait of Hormuz
Residents of southern Lebanon affected by air strikes
Israel as a nation conducting military operations

What action is being taken

Direct talks between US and Iran delegations are taking place in Bürgenstock, Switzerland
Pakistan is acting as a mediator in the negotiations
Iran has announced the closure of the Strait of Hormuz
Israel is conducting air strikes in southern Lebanon (80 targets struck on Saturday)
Israel and Hezbollah are exchanging fire despite a ceasefire confirmation
The US is criticizing Israel's ongoing operations in Lebanon
Maritime traffic continues to flow through the strait according to US military

Why it matters

This situation is significant because it involves critical geopolitical tensions in the Middle East with potential global ramifications. The Strait of Hormuz is one of the world's most strategic waterways for oil transportation, making its closure economically consequential internationally. The talks represent an attempt to implement a recently signed initial agreement between the US and Iran to end regional conflict, but ongoing Israeli-Hezbollah violence threatens to undermine diplomatic progress. The substantial civilian death toll in Lebanon (over 4,000 since March) and the involvement of multiple regional powers demonstrate how localized conflicts can escalate into broader regional instability, affecting international security and economic interests.

What's next

Further talks over the next 60 days to reach a final deal between the US and Iran
Continued management of the Israel-Lebanon security situation by the US
Implementation of commitments from the 14-point memorandum of understanding between the US and Iran
Pakistan will continue supporting implementation of US-Iran understandings
