Iraqi officials say at least six people have been killed in two separate incidents in the capital, Baghdad.
In the first incident on December 29, gunmen opened fire at a militia checkpoint in the Abu Ghraib district, killing four militiamen and injuring three others.
The checkpoint is run by an anti-Al-Qaeda, pro-government Sunni militia known as the Awakening Council.
It was formed by the U.S. military during the height of the insurgency in 2006.
They are seen as traitors by Al-Qaeda and other militant groups in Iraq.
In the second incident, two civilians were killed and eight injured when a bomb went off in Baghdad's Jihad district.
Violence in Iraq has reached its highest level since 2008.
More than 6,750 have been killed in violence in 2013, according to AFP.
