BAGHDAD, Iraq - A suicide attacker detonated a car bomb north of Baghdad on Sunday, killing 19 Iraqis -- all but one of them National Guards -- in another strike against Iraqis cooperating with American force. An Iraqi civilian was among the 19 killed while the other casualties were members of Iraq's 203rd National Guard Battalion. The driver of the vehicle also died.

In other developments Sunday, the U.S. military said that Iraqi security forces "decisively defeated" another attack by the insurgents as they attempted to seize a police station in southeast Mosul on Saturday -- the fifth such attack in a week.
