The U.S. military is in shock after an unexpected attack by Yemen's Houthi rebels, also known as Ansar Allah. The group has claimed responsibility for shooting down a U.S. MQ-9 drone over Yemen's central Marib province. According to Houthi spokesman Yahya Saree, the drone was engaged in a hostile mission in the area at the time. The drone was destroyed using a locally made missile, as confirmed by Saree. This marks a significant escalation in tensions.
