Three people were killed and 36 others injured in separate attacks targeting two major airports in Saudi Arabia, according to the kingdom’s General Authority of Civil Aviation (GACA).

Abha International Airport in southwestern Saudi Arabia and King Khalid International Airport in Riyadh were targeted on Tuesday and Wednesday as fighting between Houthi forces and the Saudi-backed Yemeni government escalated. Yemen’s Houthi movement claimed responsibility for the attacks.

At Abha airport, two women, one Moroccan and one Algerian, were killed, while 28 people were injured. GACA said the injuries ranged from minor to serious. Among those injured were Saudi citizens as well as Bangladeshi and Filipino residents.

A separate attack on King Khalid International Airport in Riyadh killed a Sudanese national and injured eight other people. The injured included five Saudi citizens, two Egyptian residents and one Pakistani resident, according to Saudi authorities. All those injured were taken to hospitals for treatment.

The attacks also caused property damage at the airports. GACA said it was coordinating with security authorities to assess the damage, verify the safety of airport facilities and take measures to protect passengers and aviation workers.

Saudi forces have continued responding to Houthi attacks. Saudi-led coalition forces said they intercepted a ballistic missile north of Riyadh and destroyed a launch platform in Yemen’s capital, Sanaa, that had been used to launch attacks toward the Saudi capital.

The latest violence comes amid a broader escalation in Yemen, where Saudi-backed government forces are fighting Houthi fighters over territory near the strategic Bab el-Mandeb Strait. The waterway connects the Red Sea with the Gulf of Aden and is an important route for global shipping and energy supplies.

The renewed fighting has also increased security concerns for commercial aviation in the region, with further Houthi attacks reported around Saudi and Yemeni airports.
