(Reuters) – U.S. missiles struck targets across Iran on Friday and President Donald Trump vowed “major military punishment” for Tehran and its Houthi allies in Yemen, though he once again left open the door to a diplomatic deal with Iran.

Two weeks after the ​collapse of an interim truce meant to end the war, the Iranian armed forces responded by firing at U.S. bases in neighbouring Arab countries and warning people there that they may strike non-military used by U.S. personnel.

“We are talking to them. I think they’re being serious. I think … they are being by far the most serious that we’ve seen them, but that doesn’t mean we get there,” Trump told reporters at the White House.
