A missile strike on King Khalid International Airport in Riyadh, Saudi Arabia, killed 12 people and injured more than 300, with some victims in critical condition.

A Saudi-led coalition blamed Iran-backed Houthi rebels in neighboring Yemen for the attack.

The strike was the deadliest attack in a Gulf Arab country since the Iran war began, as fighting continues to spread across the region.

The victims included Saudi citizens and foreign nationals from several countries, including the United States, Bangladesh, Egypt, and Jordan, the AP has reported.

Airport operations were suspended following the attack, and the closure was extended for another 24 hours until 9 p.m. Sunday.
