The Associated Press reported that the majority of the 31 American troops killed Saturday when the Taliban shot down a military helicopter over Afghanistan were members of SEAL Team 6, the elite team that killed Osama bin Laden in May.

Afghan President Hamid Karzai delivered news of the 38 total fatalities, the highest single-day U.S. death toll in the decade of U.S. military involvement in Afghanistan.

The AP cited only "AP sources" in reporting that the dead troops were part of SEAL Team 6. NATO acknowledged that the crash had happened, but did not give a reason why, or release names yet. NATO has also not released their own fatality count.

The elite special forces group came to the public's attention this spring, when details of the raid on bin Laden's compound were leaked to an awestruck country.

UPDATE: CNN is reporting that none of the SEALs in the crash were members of the operation that killed Osama bin Laden. Officials now confirm that the helicopter was shot down by insurgents.
