A U.S. aircraft crashed in southern Afghanistan, killing three U.S. service members and one civilian employee, a statement from ISAF said Friday.
The cause of the crash of the Air Force CV-22 Osprey was not known, said the International Security Assistance Force statement. Several other service members were injured in the crash late Thursday night.
The CV-22, which conducts long-range infiltration and resupply operations for the U.S. military, went down seven miles west of the city of Qalat, the capital of Zabul province.
Taliban spokesman in the region, Zabiullah Mujahid, said Taliban fighters shot down the aircraft. Another spokesman, Qari Yoseph, also claimed responsibility and said that 30 Americans had been killed.
