This information appears incomplete so far, so keep that in mind:
A NATO helicopter crashed during a battle with the Taliban in Afghanistan, killing 31 U.S. soldiers and 7 Afghans, the Afghan president said on Saturday, a devastating toll and easily the worst single incident for foreign troops in 10 years of war.
A brief statement from the presidential palace said the troop-carrying Chinook helicopter had crashed in Syedabad in central Maidan Wardak province, just to the west of the capital, Kabul, and identified the Americans as special forces troops.
The Taliban quickly claimed to have shot down the helicopter during a firefight, although the Islamist militant group often exaggerates incidents involving foreign troops or Afghan government targets. They also said eight insurgents had been killed in torrid fighting.
