“We’re putting additional sanctions on. They’re going on slowly and, in some cases, pretty rapidly, but additional sanctions are being put on Iran,” the US President said, without specifying what the fresh round of restrictions were.

Trump told reporters on Saturday that it was important to “start over” on the Islamic Republic, and rephrased his own campaign slogan, saying: “Let’s make Iran great again.”

“Hopefully Iran is smart and cares about its people,” he said, warning Tehran against any rash moves.

Trump also addressed the role of his national security advisor, John Bolton, who is believed to be the main advocate for using force against Iran. Bolton is “definitely a hawk,” Trump reportedly said, adding that he is listening to “everybody” on Iran.
