US-Iran peace talks in Switzerland disrupted as Trump threats prompt Iranian walkout

High-stakes U.S.-Iran peace talks in Switzerland were disrupted after President Trump threatened to "hit Iran very hard again," prompting a temporary walkout by the Iranian delegation. The talks, mediated by Pakistan and Qatar, aim to finalize a recent ceasefire deal. Tensions are high over Iran's closure of the Strait of Hormuz in response to Israeli strikes in Lebanon, which Iran says violate the agreement, a claim the U.S. disputes.
