Trump threatens Iranian delegation while Vance holds talks with them

• Talks underway: Vice President JD Vance and US officials are holding high-stakes talks with Iran in Switzerland. Pakistan and Qatar are mediating. The negotiations began with a focus on the conflict in Lebanon, the Strait of Hormuz and Iran’s nuclear program, a diplomat told CNN.

• Trump’s threats: Even as Vance touted early progress in Switzerland, US President Donald Trump threatened the Iranian delegation in a Fox News interview on Sunday. Trump vowed to resume bombing and “take over” the Strait of Hormuz if a deal is not reached. Iranian officials at the Swiss talks have lodged a complaint about the remarks, state media reports.

• Lebanon looms large: Fighting between Israel and the Iran-backed militant group Hezbollah has imperiled diplomatic progress. Tehran said Saturday that it was closing the strait over deadly Israeli strikes in Lebanon, though the US military has denied that Iran controls the key waterway.
