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.

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 said on Friday that he had sent a letter to the Iranian leadership warning of the possibility of a military intervention if a deal wasn’t reached.
