BAGHDAD – Signs emerged Tuesday of a reprisal sectarian slaughter of Sunnis in Iraq, as police said pro-government Shiite militiamen killed nearly four dozen detainees after insurgents tried to storm the jail northeast of Baghdad.
A local morgue official said many of the detainees had bullet wounds to the head and chest, though the Iraqi military insisted the Sunni inmates were killed by mortar shells in the attack on the facility outside the city of Baqouba.
In Baghdad, meanwhile, the bullet-riddled bodies of four men in their late 20s or early 30s, presumably Sunnis, were found at different locations in the Shiite neighborhood of Benouk, according to police and morgue officials who spoke on condition of anonymity because they were not authorized to talk with the media.
Also Tuesday, a car bomb in Baghdad's Shiite Sadr City district killed 12 people and wounded 30 in a crowded outdoor market, police and hospital officials said. No one claimed responsibility for the bombing, but attacks targeting Shiite districts are routinely the work of Sunni militants.
The Sadr City deaths take to at least 22 the number of people killed in violence in Baghdad on Tuesday.
The discovery was a grim reminder of a dark chapter in Iraq's history when nearly a decade ago the city woke up virtually every morning to find dozens of bodies dumped in the streets, trash heaps or in the Tigris river with torture marks or gunshot wounds.
The allegation of Shiite killings of Sunnis near Baqouba and in Baghdad were the first hints of the beginnings of a return to sectarian warfare that nearly tore the country apart in 2006 and 2007. Sunni militants also have been accused of atrocities -- an apparent attempt to provoke Shiite militias into revenge attacks that would strengthen the hand of an Al Qaeda splinter group within Iraq's Sunni community.
A U.N. commission warned Tuesday that "a regional war in the Middle East draws ever closer" as Sunni insurgents advance across Iraq to control areas bridging the Iraq-Syria frontier. It said Iraq's turmoil will have "violent repercussions" in Syria, most dangerously the rise of sectarian violence as "a direct consequence of the dominance of extremist groups."
During the United States' eight-year presence in Iraq, American forces acted as a buffer between the two Islamic sects, though with limited success. The U.S. military withdrew at the end of 2011, but it is now being pulled back in -- albeit so far in far fewer numbers.
The fighting around the jail was the closest to Baghdad since the Al Qaeda breakaway group the Islamic State of Iraq and the Levant began its lightning advance, seizing several key northern cities in the Sunni heartland last week.
There were conflicting details about the clashes in the al-Kattoun district near Baqouba, the capital of Diyala province and one of the bloodiest battlefields of the U.S.-led war, and on how the detainees were killed. The city is 60 kilometers (40 miles) northeast of the Iraqi capital.
Officers said the local police station, which has a small jail, came under attack Monday night by Sunni militants who arrived in two sedan cars to free the detainees. The militants fired rocket-propelled grenades on the building before opening fire with assault rifles.
A SWAT team accompanied by Shiite militiamen rushed to scene and asked the local policemen to leave, according to the officers. When the policemen later returned to the station, they found all those in the detention cells dead.
The bodies were taken to the Baqouba morgue, where an official said most had gunshot wounds to the head and chest. One detainee, however, survived and was taken to the hospital.
Police later arrived at the hospital and took the wounded man away, said a hospital official.
The police officers, the hospital and morgue officials all spoke on condition of anonymity, fearing for their own safety.
A different account was provided to The Associated Press by Iraq's chief military spokesman, Lt. Gen. Qassim al-Moussawi. He said 52 detainees who were held at the station in al-Kattoun died when the attackers from the Islamic State shelled it with mortars.
Nine of the attackers were killed, al-Moussawi said.
The Islamic State is known to be active in Diyala, a volatile province with a mix of Sunnis, Shiites and Kurds and where Shiite militiamen are deployed alongside government forces. Sunni militants have for years targeted security forces and Shiite civilians in the province, which abuts the Iranian border.
The Islamic State has vowed to march to Baghdad, and the Shiite holy cities of Karbala and Najaf in the worst threat to Iraq's stability since U.S. troops left. The three cities are home to some of the most revered Shiite shrines. The Islamic State has also tried to capture the city of Samarra north of Baghdad, home to another major Shiite shrine.
Nearly 300 armed American forces are being positioned in and around Iraq to help secure U.S. assets as President Barack Obama nears a decision on an array of options for combating the Islamic militants, including airstrikes or a contingent of special forces.
The White House has continued to emphasize that any military engagement remained contingent on the government in Baghdad making political reforms.
The U.S. and Iran, Iraq's Shiite neighbor and close ally, also held an initial discussion on how the longtime foes might cooperate to ease the threat from the Al Qaeda-linked militants that have swept through Iraq. Still, the White House ruled out the possibility that Washington and Tehran might coordinate military operations in Iraq.
The push by the Islamic State's militants has largely been unchecked as Iraqi troops and police melted away and surrendered in the onslaught on the city of Mosul and Trikrit, Saddam Hussein's hometown.
On Monday, the Islamic State captured the strategically located city of Tal Afar near the Syrian border, a move that strengthens its plans to carve out a state-like enclave on both sides of the border.
Iraqi military officials said some 400 elite troops and volunteers who have joined security forces were flown to an airport outside Tal Afar on Monday, but were immediately pinned down by heavy artillery shelling from the militants.
Iraq has been in danger of sliding back to wholesale Shiite-Sunni bloodletting since Sunni militants seized at least one city and significant parts of the countryside in Anbar province west of Baghdad early this year.
Continuous bombings blamed on Sunni militants in Baghdad and elsewhere, and targeted assassinations of members of both communities have deepened fears of outright sectarian warfare.
In Baghdad on Tuesday, a suicide bomber set off his explosives outside a central Baghdad store that sells military uniforms, killing seven people and wounding 22, according to police and hospital officials.
Elsewhere in the capital, a sticky bomb attached to a car exploded, killing three passengers and wounding 11 bystanders, according to police and hospital officials.
The officials all spoke on condition of anonymity because they were not authorized to talk to the media.Police and hospital official say a car bomb in Baghdad's Shiite Sadr City district has killed 10 people and wounded 25.
They said the blast targeted a crowded outdoor market Tuesday in the sprawling district in eastern Baghdad.
The officials spoke on condition of anonymity because they were not authorized to speak to journalists.
The latest death toll takes to 20 the number of people killed in violence in Baghdad on Tuesday.
Additionally, four bullet-riddled bodies, assumingly Sunnis, were discovered on Tuesday in a Shiite district.
The targeting of the Shiite district came as signs emerged of a reprisal sectarian slaughter of Sunnis in Iraq, as police said pro-government Shiite militiamen killed nearly four dozen detainees after insurgents tried to storm a jail northeast of Baghdad on Monday night.
