KABUL: The U.S.-led coalition says a NATO helicopter has crashed in eastern Afghanistan.

The International Security Assistance Force says all crew members have been recovered and no fatalities have been reported in Thursday's crash. It says the site of the crash has been secured, although the statement did not provide a location or other details.

Taliban spokesman Zabiullah Mujahid claims the helicopter was shot down by the group's fighters in the Tagab district of Kapisa province.

But U.S. Army Maj. Adam Wojack, an ISAF spokesman, says the cause of the crash is still being investigated and it's not yet known if there was enemy activity in the area at the time.

The Taliban spokesman also said in an email that all crew members were killed. The militants often exaggerate casualty figures.
