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.

Iran's Supreme leader has criticised "bullying" countries in an apparent response to Donald Trump's comments that he had sent a letter to Iran demanding negotiations on its nuclear programme. 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.

Iranian state media immediately picked up on Trump's acknowledgment, given in excerpts from a Fox Business News interview aired on Friday, though there was no confirmation from Khamenei's office that any letter had been received.

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 Trump said he sent a letter to Iran's Supreme Leader Ayatollah Ali Khamenei last week asking that the two leaders "negotiate" over the Islamic republic's nuclear program. On Saturday, the Iranian leader condemned the effort by unnamed "bullying governments" to make a deal over the program.
