Two strikes on the international airport in the Saudi capital of Riyadh have left 14 dead and more than 300 injured. There have been a series of other attacks earlier in the week.

CCTV footage from inside King Khalid International Airport shows people taking cover as one of the missiles hit the building on Saturday.

The Houthis in Yemen say they were behind the strikes and warned airlines and passengers against using Saudi Arabian airports and airspace. The group said they had targeted the airport with a mix of ballistic and cruise missiles, as well as drones.

They also attacked oil facilities and Dammam airport in eastern Saudi Arabia, their military spokesman Brig Gen Yahya Saree said. He vowed to continue the “escalating operations deep inside Saudi Arabia”, warning that all Saudi airports were potential targets apart from those in the holy cities of Mecca and Medina.
