Yemen's Houthis said they attacked an oil facility Sunday in southwestern Saudi Arabia, the latest attack by the Iranian-backed rebels on the kingdom. The attack was in response to Saudi drones' breaching Yemen's airspace over the provinces of Hajjah and Saada, he said. Early on Sunday, the Saudi Energy Ministry reported a fire at a facility belonging to the Aramco refinery without casualties. Sunday's Houthi attack is the latest in a series of missile and drone attacks that targeted Saudi Arabia and its shipping in the Red Sea. He added that negotiations with Oman about "new maritime routes" through the Strait of Hormuz were "in the final stages."
