The crash of a military aircraft Tuesday in Afghanistan killed six members of the International Security Assistance Force who were on board, military officials say, and NPR's Tom Bowman has been told by military sources in a position to know that all six were Americans.
Fox News and several other outlets are also reporting they've been told the casualties were Americans.
According to Reuters, the crash happened in southern Afghanistan and "did not appear, initially at least, to be the result of insurgent attack."
But, as the wire service also notes, "it was the most deadly incident for foreign soldiers in Afghanistan in months."
Fox News quotes a deputy governor of Zabul province, Mohammad Jan Rasoolyar, as saying the aircraft was a helicopter.
We'll update as more information comes in.
