Yemen's Houthis have again attacked passenger hall number 4 at the King Khalid International Airport in Riyadh, Saudi Arabia, and started a fire.

The second attack occurred less than 24 hours after a devastating Houthi missile attack on Saturday at the same compound, which houses Domestic Terminals 3 and 4.

The attack on Saturday killed 12 people and injured 309, the deadliest attack on Saudi soil in more than a decade.
