Black Hawk Down, Sunni Insurgents Say U.S. Soldiers Are Dead

CAIRO, Egypt (AP) -- An al-Qaida-linked coalition of Iraqi Sunni insurgents has claimed that its fighters shot down an American military helicopter in a crash that killed 12 U-S soldiers.

The insurgent coalition posted the claim on an Islamic Web site, saying "the lions of Iraq's Islamic state" shot down a Black Hawk helicopter on Saturday.

The posting's authenticity hasn't been independently verified, but it appeared on a Web site used as a clearing house for militant statements.

The coalition is believed to be the political wing of al-Qaida in Iraq.

A U-S military spokesman says the cause of the crash hasn't been determined.

But a senior U-S military official said today that investigators have found debris near the crash scene that could belong to a shoulder-fired weapon.
