Attacks across Iraq have killed at least 54 people and wounded dozens more.
The deadliest attacks occurred in Baghdad's northern district of Kazimiyah, when a suicide bomber drove his explosives-filled car into a police checkpoint Wednesday, killing 11 people. Police said at least 35 people were wounded.
The violence comes as politicians prepare to start negotiations to form a new government following parliamentary elections.
Prime Minister Nouri al-Maliki's bloc won the country's first parliamentary election since the U.S. military withdrawal in 2011. But it failed to gain the majority needed to govern alone.
Wednesday's violence follows a wave of attacks that killed 21 people a day earlier.
Violence in Iraq is at the highest level since the country was pushed to the brink of a sectarian civil war in 2006 and 2007.
