A wave of apparently coordinated bombing and shooting attacks in seven different provinces across Iraq killed at least 38 people and wounded more than 170 on Thursday, security officials said.
It was the deadliest day in Iraq since March 20, when shootings and bombings claimed by an Al-Qaeda front group, the Islamic State of Iraq, killed 50 people and wounded 255 nationwide.
The attacks, which come amid heightened political tension, drew an accusation from the Sunni-backed Iraqiya bloc that security measures were insufficient, and that Prime Minister Nuri al-Maliki, as head of the armed forces, was responsible for the deficiency.

The spokeswoman for the Iraqiya bloc, Maysoon al-Damaluji, pointed a finger at Maliki for the weakness of security measures to prevent the bloodshed.
"The continuation of bloody explosions, although it has been already announced that tight security measures have been taken, reflects the weak security plans and the necessity to reconsider them," the MP said in an emailed statement.
"The commander of the armed forces (Maliki) is responsible for providing security and complete safety for citizens," she said.
Political tensions have risen sharply after key Iraqi factions accused Maliki of orchestrating a slide away from the electoral process and towards dictatorship with the arrest last week of election commission chief Faraj al-Haidari, who has since been freed on bail.
