Yemen's Houthi forces launched a major attack on Saudi Arabia on Saturday, striking "sensitive sites" in the capital Riyadh and Aramco oil facilities in the port city of Yanbu using ballistic missiles, cruise missiles, and drones. A fire broke out at an Aramco fuel depot near Riyadh's King Khalid International Airport, causing widespread flight cancellations and delays, while residents reported explosions and received overnight civil defence alerts urging them to stay indoors. The strikes mark a significant escalation in the Houthi campaign against Saudi Arabia, which began in July when the group declared a naval blockade against Riyadh, and come amid broader regional instability linked to the ongoing US-Iran war, with Türkiye signalling readiness to help meet Saudi military needs under a trilateral defence pact with Pakistan and Saudi Arabia.
