A helicopter crash in southern Afghanistan killed five members of the NATO-led International Security Assistance Force, NATO said, although there were no immediate details about the cause of the crash.
A brief ISAF statement said the crash occurred on Monday.
"The cause of the crash is under investigation, however initial reporting indicates there was no enemy activity in the area at the time of the incident," the NATO statement said.
It also did not give any details about the nationality of the troops killed, although US and British forces make up the bulk of the NATO-led contingent in Afghanistan's south. Australian troops also still operate in the south.
