Iran's supreme leader Ayatollah Ali Khamenei on Saturday slammed what he described as bullying tactics a day after US President Donald Trump threatened military action.

"Some bully governments -- I really don't know of any more appropriate term for some foreign figures and leaders than the word bullying -- insist on negotiations," Khamenei told officials after Trump threatened military action if Iran refuses to engage in talks on its nuclear programme.

"Their negotiations are not aimed at solving problems, they aim at domination," Khamenei said.
