U.S. airstrikes in Yemen's capital killed 12 people and wounded 30 others, according to Houthi rebels. The strikes targeted the Farwa neighborhood market in Sanaa's Shuub district. The U.S. military's Central Command has not commented on the strike or civilian casualties. The strikes come amid negotiations between the U.S. and Iran over Tehran's nuclear program, which the U.S. has linked to its attacks in Yemen.
