Houthi forces in Yemen have escalated attacks on Saudi aviation infrastructure, striking Riyadh’s King Khalid International Airport with ballistic missiles and drones on October 8, 2026, and targeting southern airports including Abha, Najran, and Jazan earlier in the week. These strikes killed at least three people, prompted Saudi authorities to close Najran and Jazan airports until October 15 and restrict Abha to daytime operations, and triggered hundreds of flight cancellations. The European Union Aviation Safety Agency expanded its conflict-zone advisory to additional Saudi airspace sectors, while OPSGROUP issued a broad “do not fly” recommendation citing missile risks and defensive response hazards. Houthis have threatened further strikes on commercial aircraft in Saudi skies except over holy cities. Saudi airspace remains open overall, though international carriers have suspended Riyadh routes and regional tensions continue to elevate operational risks.
