.As the U.S. forces began their assault on the Al Qaeda compound in Bayda province, they engaged in an intense firefight left at least 14 militants dead, said a U.S. official, who wasn’t authorized to speak publicly on the secret mission. One commando was killed and three others wounded during the battle, which lasted about an hour
During the operation, U.S. troops grabbed a cache of the militants' laptops, cellphones and other materials, which was what U.S. commanders were seeking in the rare on-the-ground siege against Al Qaeda in the Arabian Peninsula, known as AQAP. The U.S. military typically relies on drone strikes against the group.
During the raid, a V-22 Osprey tilt-rotor aircraft that was assisting in the operation crash-landed at a nearby location, resulting in an additional service member injury, said a U.S. official who wasn’t authorized to speak publicly on the secret mission.
The aircraft, which was sent to evacuate the wounded, was unable to fly after the landing. U.S. warplanes later destroyed it.
