Iran's delegation declined to return to quadrilateral talks following threats from Trump, although messages were exchanged via Qatari and Pakistani mediators.
Ongoing discussions between U.S. diplomats and Iran since Sunday focus on a ceasefire in Lebanon, access to the Strait of Hormuz, and the nuclear deal. Progress has been made to keep the Strait open despite Iranian threats, with all parties expressing satisfaction with initial talks. High-level discussions conclude Monday, while technical teams will continue negotiations in Switzerland.
