Yemen's Iranian-backed Houthi movement has said its forces attacked two Saudi oil tankers in the Red Sea that had "violated" its blockade of Saudi ports, as the US carried out a 12th consecutive night of strikes on Iran. The official Saudi news agency confirmed that one tanker was hit late on Wednesday, causing a fire. US President Donald Trump warned the Houthis on Thursday that if they did so again, the US would inflict "major military punishment" upon both them and Iran. Iranian state media said two people were killed in US strikes on Wednesday night, while Jordan and Kuwait intercepted missiles and drones launched by Iran. The IRGC also said a tanker caught fire following an explosion in a mined route in the Strait of Hormuz, a vital waterway in the Gulf that is effectively closed.
