U.S. and Iranian negotiators headed to a Swiss venue Saturday for talks on adding key details to their interim agreement to halt the war, hours after Tehran said it closed the Strait of Hormuz because of Israel's attacks in Lebanon and warned that little might be achieved if the fighting doesn't stop. This was reported by Qazaqyia.kz citing Associated Press.

U.S. Vice President JD Vance met with Pakistan's Prime Minister Shehbaz Sharif at the Bürgenstock Resort in Obbuergen, near Lucerne. The meeting was also attended by U.S. President Donald Trump's envoys Steve Witkoff and Jared Kushner.

Speaker of the Islamic Parliament of Iran Mohammed Bagher Ghalibaf also arrived in Switzerland. Qatar and Pakistan are also participating in the talks. Flags of Switzerland and Nidwalden were seen at the venue.

Earlier, Tehran said it closed the Strait of Hormuz because of Israel's attacks on Lebanon. Iran warned that if the fighting does not stop, little might be achieved in the talks.
