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.

A day earlier, Iran’s Supreme Leader Ali Khamenei had rejected talks with the U.S., because he said they would be aimed at imposing restrictions on Iranian missile range and its influence in the region.

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.
