At least 12 people have been killed and more than 300 injured in Saturday's attack on King Khalid International Airport in Riyadh, Saudi Arabia. A Saudi-led coalition labelled the incident a "war crime" and has blamed Yemen's Houthis - who have not commented on Saturday's attack but did say they were behind separate strikes on the same airport on Thursday. Yemen's Houthis have issued a new warning to all airline companies to not use Saudi airports. In a statement put out by the group's military spokesman Yahya Saree, he said that the Iran-backed group "reiterate their warning... against using Saudi airports and airspace". This is because "they are potential targets and sites for operations by our forces". Saree said that Mecca and Medina are excepted from this.
