Fresh turbulence has hit the Swiss negotiations after Donald Trump’s latest warning sparked anger inside Tehran. Iranian media claimed negotiators formally protested the remarks, while reports suggested Iran’s delegation temporarily left the venue amid growing tensions. Parliament Speaker Mohammad Bagher Ghalibaf warned Washington that threats would only invite action, saying “the more they talk, the more we act.” With both sides trying to salvage a fragile diplomatic process, Trump’s comments have raised fears that the latest round of U.S.-Iran talks could face serious disruption just as hopes for a broader breakthrough had emerged.
