Shocking video released Monday shows the moment Houthi terrorists bombed Riyadh international airport, killing13 people and injuring more than 300 others.

Unsuspecting travelers were calmly waiting in lines inside the terminal of King Khalid International Airport on Saturday when there was a sudden, giant explosion, the footage released by Saudi Arabia’s Media Ministry shows.

Travelers rushed for cover as smoke filled the terminal building and a small fire was seen raging.

Other passengers frantically ran through security checkpoints while airport workers cowered under their desks in terror as pieces of the roof crashed towards the floor.

King Khalid airport, which has been struck four times in the past five days, has been closed since Saturday’s missile attack – the deadliest in a Gulf Arab nation since the Iran war began. A projectile struck the same passenger terminal on Sunday.

The Iran-backed Houthis have since claimed responsibility for the airport attacks — and threatened more to come.
