BAQOUBA, Iraq - Two suicide bombers blew themselves up in a crowd of army recruits Tuesday in an Iraqi province where devastating attacks persist despite security improvements in the rest of the country. At least 28 people died, the Iraqi police and military said.
The blasts at the Saad military camp in Baqouba, the capital of Diyala, recalled the scenes of mass terror and grief that were almost a daily routine in previous years. Violence in Iraq is at its lowest level in about four years.
AP Television News footage showed medical staff unloading white body bags from ambulances, soldiers on their knees weeping over slain comrades and the wounded moaning as they lay on gurneys and even on the bloodstained floor of a hospital room.
The explosions killed 28 people and wounded at least 57 recruits, a police official said. He spoke on condition of anonymity because he was not authorized to speak to the media.
A military officer in Baqouba, 35 miles (60 kilometres) from Baghdad, confirmed the death toll and said soldiers were among the casualties. He also spoke on the same anonymity condition.
The U.S. military said in a statement that the attack occurred around 8 a.m. It said 20 police recruits were killed and 55 were injured. There was no immediate explanation for the discrepancy in the reports.
Diyala is critical to Baghdad's security because of its strategic importance as an entrance to the capital and a threat to supply routes going north. The volatile, ethnically mixed area also borders Iran, which the United States has accused of helping militants to stage attacks on American troops.
Last year, U.S. troops largely subdued militancy in Baqouba, which had been held by al Qaeda in Iraq and other Sunni extremist groups. But many insurgents were believed to have melted away and now appear to be regrouping.
Loyalists of Saddam Hussein's regime had homes in Buhriz, a southern suburb of Baqouba, and the area served as a staging ground for Sunni attacks that drove Shiites out of the city.
Abu Musab al-Zarqawi, leader of al Qaeda in Iraq, was killed by a U.S. airstrike in Diyala province in June 2006.
On June 22, a female suicide bomber concealing explosives beneath her black robe struck outside a government complex in Baqouba. At least 15 people were killed and more than 40 were wounded. A car bomb across the street from the same compound killed at least 40 people in April.
The decline in violence in Iraq has been driven by a variety of factors, including the 2007 U.S. troop surge and a Sunni revolt against al Qaeda in Iraq. U.S.-backed Iraqi forces have scored successes in offensives against Shiite militants in Baghdad's Sadr City district and the southern cities of Basra and Amarah, and against Sunni extremists in Mosul in the north.
Iraq's Interior Ministry spokesman, Maj. Gen. Abdul-Karim Khalaf, said Sunday that the government's planned operation in Diyala would be "the last surge.''
Al-Mada, an Iraqi newspaper, on Tuesday reported Khalaf as saying that the file on the Diyala operation had been handed to Prime Minister Nouri al-Maliki, who will decide when to launch it.
Also Tuesday, the U.S. military said it had captured the Iranian-trained leader of an explosives cell in the Adhamiyah district of Baghdad. It said the suspect has been linked to attacks against U.S. and Iraqi bases in the capital.
