At least 107 people have been killed in a number of bomb and gun attacks in Iraq.
Another 268 other people were injured in bomb attacks in Shia areas of Baghdad, the Shia town of Taji to the north, the mixed northern city of Kirkuk and elsewhere, hospital and police sources said.
The bloodshed highlighted the deficiencies of the Iraqi security forces, which failed to prevent insurgents from striking in multiple locations across the country.
No group has claimed responsibility for the latest wave of assaults, but a senior Iraqi security official blamed the local wing of al-Qaeda.
In Taji, 20km north of Baghdad, six blasts went off near a housing complex. A seventh blast there caused carnage among police who had arrived at the scene of the earlier attacks.
In all, 32 people were killed, including 14 police, and 48 wounded.
Two car bombs struck near a government building in Sadr City in Baghdad and in the mainly Shia area of Hussainiya on the outskirts of the capital, killing a total of 21 people and wounding 73, police said.
Nine people, including six soldiers, were killed in attacks in the northern city of Mosul, police and army sources said.
In the northern oil city of Kirkuk, five car bombs killed six people and wounded 17 others.
