US Secretary of State Marco Rubio has warned Iran not to retaliate against US strikes, saying that would be “the worst mistake they’ve ever made”.

Mr Rubio, who also serves as National Security Adviser, made the comments on a Fox News show.

He added that the US air strikes on Iran’s nuclear facilities made the world more secure, Secretary of State Marco Rubio asserted Sunday, rejecting fears that the action could ignite a wider conflict.

“I think the world today is safer and more stable than it was 24 hours ago,” he said, warning Iran that it risked further reprisals if it insisted on maintaining a “secret” nuclear program.

Mr Rubio accused Iran of entering into “fake negotiations” ahead of the strikes in a bid to “play” US President Donald Trump.
