President Donald Trump warned on Monday that he would order fresh U.S. attacks on Iran's nuclear facilities should Tehran try to restart facilities that the United States bombed last month. Trump issued the threat as he held talks with British Prime Minister Keir Starmer at his Turnberry golf resort on the western coast of Scotland.
