KABUL, Afghanistan, Jan. 19 (UPI) -- A NATO helicopter crashed in Afghanistan's southern Helmand province, killing six soldiers, NATO said.
There was no enemy activity in the area at the time the copter went down late Thursday, said Col. Gary Kolb, spokesman for NATO's International Security Assistance Force, CNN reported.
The cause of the crash was under investigation, the report said. The nationalities of those killed were not known immediately.
Thirty soldiers, including 22 U.S. Navy Seal forces, died in August 2011 in the worst such helicopter crash in Afghanistan.
