Iran’s U.N. mission said it would be willing to discuss its nuclear program if talks were restricted to military concerns, after its supreme leader appeared to reject President Trump’s offer to start discussions.

Iran’s Supreme Leader Ayatollah Ali Khamenei has said calls for negotiations by “bully states” are aimed at dominating others, not resolving issues, after US President Donald Trump urged him to reach a nuclear deal.

President Donald Trump says he sent a letter to Iran’s Ayatollah Ali Khamenei, a development that was not immediately confirmed by the supreme leader.

Trump revealed this week that he was seeking to strike a new deal with the Iranian regime, after withdrawing from an Obama-era agreement in his first term.

Ayatollah Ali Khamenei decried “bullying governments” in an apparent response to a letter the White House sent to Iran earlier in the week.

Iran says it would consider negotiations with the United States if talks were confined to concerns about the militarization of the country’s nuclear program.

Ayatollah Ali Khamenei, Iran's supreme leader, said in a series of X posts Saturday he would not negotiate a nuclear deal with the U.S. due to its demands.

The Kremlin, asked on Monday if Russia had held consultations with Iran before or after Tehran responded to a letter from U.S. President Donald Trump urging the country to negotiate a nuclear deal, said Iran formulates its own policy positions.

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.
