The Houthis escalated attacks on Saudi Arabia, striking Riyadh's King Khalid International Airport twice in two days and hitting an Aramco building in Dhahran, causing a 'limited fire,' according to Saudi officials. The Saudi-led coalition said Riyadh's airport alone had been attacked 20 times since Oct. 1, killing 17 and injuring hundreds, prompting Canada to advise citizens against travel to Saudi airports and Saudi officials to issue civil defense alerts for Jazan. Saudi Arabia's deputy foreign minister called the Houthi strikes on civilian and airport infrastructure 'full-fledged war crimes,' citing threats to Mecca, Medina and Umrah pilgrims, and a minister vowed a 'serious response.' Analysts say the campaign reflects Iran-backed Houthi efforts to use Tehran's financial and military support to pressure Riyadh into concessions on Yemen, with some warning the conflict could widen into a broader Gulf confrontation.
