Iraqi officials say two bomb attacks have killed at least five members of the security forces.
In the bigger of the two attacks on November 25, a suicide bomber rammed his explosives-laden car against a police checkpoint in southern Baghdad, killing three policemen and wounding four others.
Earlier in the day, a roadside bomb struck the car with two anti-al-Qaida Sunni militiamen in Baghdad's northeastern suburb of Husseiniyah, killing them both.
The UN says more than 7,000 people have been killed in sectarian and other attacks in Iraq this year.
October was Iraq's deadliest month since April 2008, with almost 1,000 people killed.
