CH-53 down in Afghanistan.

Just heard on a radio that a CH-53 went down in Afghanistan in Helmand province.  Its unknown (more precisely they aren't saying what caused the crash) what caused the incident, but all 6 people on board were killed.  This from ABC News via AP...

A NATO helicopter crashed in southern Afghanistan on Thursday, killing six members of the international military force, the U.S.-led coalition said.
The coalition said in a release early Friday morning that there was no enemy activity in the area at the time of the crash in southern Afghanistan.
The cause of the crash is still being investigated. The coalition did not disclose the nationalities of those killed.
The helicopter crash occurred on the same day seven civilians were killed outside a crowded gate at Kandahar Air Field, a sprawling base for U.S. and NATO operations, after a suicide attacker set off a vehicle laden with explosives. The Taliban claimed responsibility, claiming they were targeting a NATO convoy.
It was the second suicide bombing in as many days in southern Afghanistan, officials said. The coalition said no NATO troops were killed. It does not disclose information about injured troops.

Rest in peace to the fallen and comfort to their families.
