President Donald Trump says the U.S. destroyed military sites on an island vital to Iran’s oil network and warned that the island’s oil infrastructure could be next if Iran continues to interfere with the passage of ships through the Strait of Hormuz. Trump says U.S. forces on Friday “obliterated” targets on Iran’s Kharg Island, home to the primary terminal that handles the country’s oil exports. Meanwhile, an American official says 2,500 more Marines and an amphibious assault ship are being sent to the Middle East nearly two weeks into the war with the Islamic Republic.
