Bomb attacks in the capital and north of Baghdad killed at least 15 in Iraq Monday, according to the Associated Press. 
In Baghdad, a roadside bomb targeting Sahwa, anti-Al Qaeda Sunni fighters,  left two dead and three wounded in the capital's southwestern suburbs.
In the town of Buhriz, north of Baghdad, a carb bomb outside a cafe killed 12 and wounded 24.
Slightly south of the capital, another soldier was killed and two more wounded when a bomb detonated near an army patrol.
No group has come forward to claim responsibility for Monday's attacks, but security forces and the Sahwa have been militants' major targets. Many of the attacks have been orchestrated to undermine confidence in the Shi'ite-led central government and punish the Sunni Sahwa who are considered traitors by many militants due to their cooperation with US forces during the war.
The culmination of the routine attacks have stoked sectarian tensions throughout the country, with already 144 killed in the country since the beginning of December.
