A missile strike on Riyadh's King Khalid International Airport killed 12 people and injured more than 300 others, Saudi civil aviation authorities reported early Sunday. The attack damaged a complex housing terminals 3 and 4 used for domestic flights, according to a regional official who spoke on condition of anonymity because they were not authorised to speak to media.

A Saudi-led coalition attributed the strike to Iran-backed Houthi rebels based in neighbouring Yemen. The Guardian reported that some of the injured were in critical condition.

The attack occurs as the Trump administration evaluates whether the United States should join Saudi strikes against the Houthi movement. The sourced material does not detail any prior context for the attack, the specific capabilities used, casualty breakdowns, operational impact on the airport, or statements from the Houthis themselves.
