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.

Iran's Supreme Leader Ayatollah Ali Khamenei said on Saturday that Tehran will not be bullied into negotiations, a day after U.S. President Donald Trump said he had sent a letter to the country's top authority to negotiate a nuclear deal.
