Yemen’s Iran-aligned Houthi group said it attacked a major Saudi Aramco facility near Riyadh with ballistic missiles and drones, claiming the operation caused fires in retaliation for Saudi airstrikes on Houthi-held areas. Flames and heavy smoke were seen at an Aramco refinery on Saturday as firefighters responded, though Saudi authorities and Aramco had not confirmed the cause of the blaze. Fighting also intensified around Taiz, where the Houthis launched coordinated attacks along an approximately 15-kilometre front, while government-aligned forces reported operations in Taiz and Lahij. Separately, U.S. Defense Secretary Pete Hegseth said Washington’s blockade around the Strait of Hormuz remained ironclad as Iran’s rial fell near 2.7 million per dollar on the free market. Russia said it was prepared to mediate between Washington and Tehran.
