Two civilians were killed in the south of Saudi Arabia from a missile launched from Yemen by the Houthi movement. Saudi state media reported this on Saturday night.
The Houthis, an Iran-allied group that controls much of Yemen including the capital Sanaa, have fired a series of missiles into the kingdom in recent months,
part of a three-year-old conflict in Yemen widely seen as a proxy battle between Saudi Arabia and Iran.
A U.S.-backed, Saudi-led military coalition is fighting against the Houthis on behalf of the government of President Abd Rabbu Mansour al-Hadi, who lives in exile in Riyadh.
