Saudi Arabia has opened an investigation into why its air defense systems failed to intercept a barrage of drones and missiles launched by Houthi rebels at Riyadh's King Khalid International Airport. Two regional officials, speaking on condition of anonymity, stated on Monday, Oct. 12, 2026, that the probe aims to determine how the weaponry traveled more than 1,000 kilometers (621 miles) without being stopped. The attack resulted in at least 13 deaths and more than 300 injuries.
The incident occurred amid a regional conflict involving the United States, Israel, and Iran that began approximately seven months ago. Preliminary findings from the Saudi investigation suggest that Houthi forces used multiple drones before launching a combination of cruise and ballistic missiles. Saudi Energy Minister Prince Abdulaziz bin Salman stated at an oil congress in Riyadh that the recent events are serious and require an appropriate response.
Regional officials noted that the Houthis possess advanced ballistic systems with warheads capable of changing trajectory in flight, which can bypass Patriot interceptors and other defense systems used by the Saudi military. Despite the strike, Saudi Arabia continued with the second day of the World Petroleum Congress on Monday, though the airport remained closed and financial district employees were told to work from home.
The attack directly affected travelers and residents in Riyadh, as King Khalid International Airport remained closed as of Monday. Saudi officials say the advanced technology used by the Houthis bypasses existing radar and interceptor systems. If the U.S. decides to intervene directly with strikes, as President Donald Trump suggested on Saturday, Oct. 10, the conflict could prompt the Houthis to try to halt shipping through the Bab el-Mandeb Strait. Such a disruption could affect global oil markets.
Saudi officials are seeking more active U.S. engagement in countering Houthi attacks. Saudi state media reported on Monday that the military was responding to new drone and cruise missile attacks. Future developments depend on whether the U.S. moves to direct military action, a possibility under consideration by the White House ahead of the U.S. midterm elections.
