The UK advised against all but essential travel to Riyadh, Aseer, Najran and Jizan provinces, and against travel within 10 kilometers of the Saudi border with Yemen. The US has warned Americans across the Middle East of possible flight cancellations and airspace closures, saying Saudi-Houthi hostilities “have the potential to escalate rapidly.” US government employees in Saudi Arabia now need special authorization to use King Khalid airport.
Houthi spokesman Yahya Saree said the group targeted King Khalid with two cruise missiles, Najran airport with a ballistic missile and Khamis Mushait airbase with another ballistic missile on Thursday evening.

Earlier attacks on King Khalid and Abha airports on October 6 and 7 killed three people and injured 36, Saudi aviation authorities said.
