The escalation follows a coordinated Houthi strike on Oct 5 that hit the 400,000 BPD Aramco refinery in Rabigh and damaged King Khalid International Airport in Riyadh, where reports indicate a large crater. In response to 60 Saudi airstrikes in 24 hours, the Houthis warned international airlines to avoid Saudi airspace except over Mecca and Medina. While the Riyadh airport has since reopened, flights have faced mass cancellations and disruptions due to the ongoing instability.
