Suicide bomber kills 15 in Iraq

Hospital officials confirmed the casualties. All officials spoke on condition of anonymity because they weren't authorized to release the information.

Iraq's small Shabak community is mostly concentrated around Mosul, the provincial capital of the ethnically mixed Ninevah province, which is predominantly Sunni Muslim. Many were driven out of the city by Sunni militants during the sectarian fighting that raged after the 2003 U.S.-led invasion.

The Shabak have their own distinct language and are primarily Shiite Muslim.
