At least 60 people were reported killed and more than 225 wounded in a wave of bombing and shooting attacks across Iraq on February 23.
Reports quoting police officials and witnesses said the attacks appeared to target mostly security forces in predominantly Shi'ite areas.
No one has claimed responsibility for the attacks but the Interior Ministry said they were the work of Al-Qaeda-linked insurgents.
Most of the apparently coordinated attacks occurred in Baghdad, but deadly attacks were also reported in several other cities, including Baquba, Kirkuk, and Mosul.
Parliament speaker Osama al-Nujaifi said the attacks were aimed at stoking sectarian tensions between Shi'a and minority Sunnis and derailing an Arab League summit scheduled to be hosted by Baghdad at the end of March.
The United Nations and the United States have condemned the day's violence.
