Insurgents killed at least 10 Iraqis Wednesday as politicians worked to agree on a draft constitution in time for Monday's deadline.
Iraqi police say a car bomb in western Baghdad killed six people. North of the capital, insurgents attacked an Iraqi army checkpoint, killing four soldiers near Beiji.
The U.S. military says a roadside bomb killed four American soldiers near that town late Tuesday. A fifth U.S. soldier was killed Tuesday by small arms fire near Habbaniyah.
Despite the violence, Iraqi political groups met after two days of formal talks among political leaders failed to resolve differences over several key constitutional issues.
Also, the U.S. military Wednesday announced the end of its joint anti-insurgent offensive with Iraqi forces in western Iraq. The military says 36 suspected insurgents were detained and nine car bombs discovered during the operation.
