Saudi Arabia lifts alert in southern city a day after Houthi strikes

Sept 9 (Reuters) - Saudi Arabia's Civil Defense lifted an alert it had announced in the southern city of Khamis Mushait on Wednesday, a day after Houthi attacks there and in three other nearby cities wounded 73 people and set oil installations ablaze. Yemen's Iran-aligned Houthis struck an airbase in Khamis Mushait and oil infrastructure in the nearby cities on Tuesday in one of the biggest attacks in Saudi Arabia since the start of the U.S.-Israeli war on Iran in February. Saudi authorities did not provide details for the reasons behind Wednesday's alert in Khamis Mushait.
