This came after Iranian state media said Trump had “claimed to have sent a letter to the Leader of the Islamic Revolution on negotiations with the Islamic Republic.”It wasn’t clear if there was a physical letter involved or merely messaging.

Iran would consider negotiations with the U.S. if the aim of the talks was to address concerns regarding any potential militarization of its nuclear program, Iran's U.N. mission said on Sunday in a post on X.

Trump said on Friday he had warned Tehran in a letter it could face military action unless it agreed to talks for a nuclear deal. In a furious response on Saturday, Ayatollah Ali Khamenei said Iran would not negotiate with "bullying governments" insisting on talks.
