Yemen's Houthis claimed responsibility for targeting Dammam, Riyadh's King Khalid International Airport and Aramco's Shedgum gas facility and Tanajib oil refinery in four operations over the past 24 hours using ballistic missiles, cruise missiles and drones. The group warned airlines against using Saudi airports, except those serving Mecca and Medina.
Earlier Sunday, an unidentified projectile struck Terminal 4 at Riyadh's airport, causing a fire and injuries, Saudi authorities said. Air defenses separately intercepted a cruise missile nearby. Saturday's attack on the same airport killed 13 people and injured more than 300.
