At least 12 people have been killed and 309 injured in Saturday's attack on King Khalid International Airport in Riyadh, Saudi Arabia. A Saudi-led military coalition later vowed to respond to the attack, which it called a "war crime" and blamed on Yemen's Houthis. The Houthi statement on Sunday did not reference Saturday's attack - but the Iran-back group said they were behind separate strikes on the same airport on Thursday. The Saudi-led coalition said on Sunday that further attacks have been launched against King Khalid International Airport, in Riyadh. Maj Gen Turki al-Maliki, the official spokesman for the coalition, says that an "unknown projectile" hit Passenger Hall No 4 at the airport, causing a fire which authorities were dealing with. In a separate update, he said that air defences have intercepted a cruise missile in the vicinity of the airport.
