Yemen's Houthis targeted Aramco facilities in the Saudi Arabian cities of Abha, Najran and Jizan, as well as an airbase in Khamis Mushait, with ballistic missiles and drones. The Houthi attacks on Saudi Arabia came after they accused Riyadh of an attack on a prison that killed 17 people, according to the Houthi Ministry of Health. The revived war between the Houthi rebels and pro-government forces in southwest Yemen has forced nearly 20,000 people to flee their homes, the International Organization for Migration says.
