The Associated Press reports that "a military helicopter was shot down in Afghanistan, killing 31 U.S. special operation troops, most of them from the elite Navy SEALs that killed al-Qaida leader Osama bin Laden, along with seven Afghan commandos."
It was the deadliest single incident for American forces in the decade-long war.
The Taliban claimed they downed the helicopter with rocket fire while it was taking part in a raid on a house where insurgents were gathered in the province of Wardak late Friday. It said wreckage of the craft was strewn at the scene. A senior U.S. administration official in Washington said the craft was apparently shot down by insurgents. The official spoke on condition of anonymity because the crash is still being investigated.
NATO confirmed the overnight crash took place and that there "was enemy activity in the area." But it said it was still investigating the cause and conducting a recovery operation at the site. It did not release details or casualty figures.
