BAGHDAD - Al-Qaida's branch in Iraq claimed responsibility Tuesday for audacious raids on two high-security prisons on the outskirts of Baghdad this week that killed dozens and set free hundreds of inmates, including some of its followers.
The statement issued in the name of the Islamic State of Iraq and the Levant, the al-Qaida affiliate in Iraq, was posted on an online jihadist forum. It said months of planning went into the highly coordinated assaults on the prisons in Abu Ghraib and Taji that began late Sunday.
The attacks, among the most stunning in Iraq since a surge in violence began in April, have drawn sharp criticism from opposition lawmakers and ordinary Iraqis over the government's efforts to keep the country safe. The spike in bloodshed is intensifying fears of a return to the widespread sectarian killing that pushed the country to the brink of civil war after the 2003 U.S.-led invasion.
In its statement, al-Qaida in Iraq dubbed the prison operation "Conquering the Tyrants," and described it as "a bold raid blessed by God" that followed a series of earlier attacks that "shook the pillars of the Safavid project."
That is a reference to what some Sunni Muslims see as undue Iranian influence over Iraq and its Shiite-led government. The Safavid dynasty, concentrated in what is today Iran, ruled stretches of the Mideast from the 1500s and promoted Shite Islam as the state religion.
Al-Qaida said the prison operation involved 12 car bombs, military-style barrages of rockets and missiles, suicide bombers and help from prisoners who had managed to obtain weapons on the inside.
Iraqi officials have said at least 25 members of the Iraqi security forces were killed in the attacks, along with at least 21 prisoners and 10 militants.
Al-Qaida claimed its men killed more than 120 government forces, and that on its side, only the suicide bombers died in clashes that raged for hours.
Iraq's central government has not provided a clear account of what happened or said how many prisoners escaped.
The Interior Ministry has said several prisoners got away during the raid on Abu Ghraib, the infamous prison in Baghdad's western suburbs that was the site of well-publicized prisoner abuse at the hands of the U.S. military following the 2003 invasion.
But several Iraqi officials, including members of parliament's security and defense committee, have said more than 500 inmates escaped. Both prisons house thousands of inmates, including convicted al-Qaida militants, though it appears no one broke out of the Taji prison.
Al-Qaida said in its statement that the attack freed hundreds of detainees, including more than 500 mujahideen, or holy warriors.
The authenticity of the statement could not be independently confirmed. It was posted on a website commonly used by jihadists and its style was consistent with earlier al-Qaida statements.
The prison break could help bolster al-Qaida's ranks and give them a propaganda boost.
"Al-Qaida needs as much resources as it can get, including manpower," said Paul Floyd, who served several tours in Iraq with the U.S. Army and is now a military analyst at global intelligence company Stratfor. "The larger the operation, the more successful it is, the more likely they are to claim it."
Iraqi authorities locked down areas around both prisons as they carried out manhunts. A curfew continued around Abu Ghraib into Tuesday, and police increased the number of checkpoints on roads in the area.
Prime Minister Nouri al-Maliki voiced disappointment over the handling of the Abu Ghraib attack in brief comments made during a broader discussion aired on state television.
"I have imposed harsh punishments on some people in relation to Abu Ghraib," he said, without elaborating.
In the statement, al-Qaida also claimed responsibility for other unspecified attacks over the past four months in response to a heavy-handed crackdown by security forces on a Sunni protest camp in the northern town of Hawija on April 23.
The Hawija raid killed 44 civilians and one member of the security forces, according to estimates by the United Nations. It followed months of rallies by Iraq's minority Sunnis against the Shiite-led government over what they contend is second-class treatment and the unfair use of tough anti-terrorism measures against their sect.
Violence in Iraq has spiked to the highest level in half a decade in the wake of the Hawija crackdown. More than 3,000 people have been killed since the start of April, including more than 500 since the start of July.
Al-Qaida's claim of earlier attacks likely refers to a series of large-scale, synchronized bombing campaigns that have rocked Iraq in recent months, including a wave of a dozen car bombs that tore through Baghdad late Saturday and killed nearly 60.
Iraqi security forces have struggled to quell the violence, angering many Iraqis. The prison attacks have only increased the sense of insecurity.
"What happened in Abu Ghraib is a mixture of obvious security shortcomings, incompetence, complicity (and) inefficiency," said Baghdad-based political analyst Hadi Jalo. "The top commanders - including officers, ministers and officials - and the Iraqi government share the blame."
The bloodshed continued into Tuesday.
Insurgents bombed a local government building in the village of al-Rashad, outside the ethically disputed northern city of Kirkuk. The attackers kidnapped two anti-al-Qaida Sunni militiamen who were guarding the building and later shot them dead, according to Rashad mayor Lious al-Fandi.
Security forces were also targeted near the northern city of Mosul.
Police found four bodies of off-duty policemen on a road about 30 kilometers (20 miles) north of the city, Iraq's third largest and a major gateway to Syria. The policemen, who were on leave and heading home, were killed with bullets to the head, according to authorities.
And gunmen in a speeding car shot dead two other off-duty policemen as they were walking in a street in Mosul, police said.
Morgue officials confirmed the deaths. The officials who provided details of the attacks spoke on condition of anonymity because they weren't authorized to talk to the media.
