Islamabad, 11 October, 2026 (Kamran Raja): Yemen’s Houthi movement has renewed warnings to airlines, travellers and airport workers to avoid Saudi airports and airspace following a deadly attack on Riyadh’s international airport that reportedly killed 12 people and injured more than 300 others. The attack, described as the deadliest of its kind in Saudi Arabia in more than a decade, comes amid escalating clashes between the Iran-backed Houthis and Saudi-backed Yemeni government forces. In a statement posted on social media platform X on Sunday, the Houthis warned that Saudi airports and airspace had become potential targets, while excluding airports in the holy cities of Makkah and Madina from the warning. The group also cautioned that Saudi Arabia would bear responsibility for any unsuccessful interception of incoming attacks. Meanwhile, Saudi Arabia has intensified its military operations in Yemen in recent weeks, launching strikes against Houthi positions and supporting a government counteroffensive after the group seized strategic territory along the Red Sea coast last month. The Houthi-run foreign ministry warned that further Saudi military action would provoke a stronger response, saying the group would act according to the principle of reciprocity. US President Donald Trump also said on Saturday that Washington was considering joining Saudi strikes against the Houthis as the conflict increasingly overlaps with the wider war involving Iran, which the United States and Israel launched in February, according to the report. Separately, the Saudi-led coalition reported that a projectile had fallen near King Fahd International Airport in Dammam, while a drone was intercepted in the Eastern Province on Sunday. The attack temporarily disrupted operations at King Khalid International Airport in Riyadh. However, Saudi authorities said a long-planned international energy conference would proceed as scheduled, with the five-day WPC Energy Congress expected to bring together ministers, business executives and representatives of international energy organisations. Saudi authorities also announced that in-person classes would be suspended and replaced by remote learning from Sunday through Thursday for students, teachers and administrative staff. According to Saudi authorities, the 12 people killed in Saturday’s attack included four Saudi nationals and two Bangladeshis, as well as citizens of the United States, Jordan, Palestine, Syria, Sudan and Egypt. The civil aviation authority said airport operations had been temporarily suspended pending damage and safety assessments, with no immediate date announced for the resumption of flights. The incident marked the third reported attack on Riyadh’s international airport within a week, following earlier attacks that killed four people and severely damaged a Saudi commercial aircraft parked on the tarmac.
