Iran says the Strait of Hormuz is closed again over Israel’s continued attacks on Lebanon, but the US military says the waterway remains open to all vessels. Hezbollah has rejected the Lebanese government’s direct talks with the US, saying the negotiations would undermine Lebanon’s sovereignty and serve Israeli interests.

US-Iran war highlights: Iran's delegation left for Tehran after nearly 18 hours of intensive discussions in Switzerland, FM Abbas Araghchi said. Meanwhile, Lebanese President Joseph Aoun discussed efforts to maintain a ceasefire and halt Israeli military escalation during a call with JD Vance.

Vice President JD Vance said Monday he felt great about the progress made in more than 18 hours of Iran talks. Ed O'Keefe reports on the current state of the war.

The United States and Iran signalled on Friday that an agreement to end their war was close, with a senior US administration official saying both sides had agreed on a text and that Washington expects to sign an initial deal in the coming days.

Iran's delegation on Sunday walked out of the Swiss venue where it held talks with the United States towards permanently ending the West Asia war, after Donald Trump threatened to strike the Islamic Republic over its support for Hezbollah.

President Trump has not signed off on the emerging framework, according to U.S. officials. But it could set the table for extending the cease-fire and more substantive negotiations.
