Baghdad, Iraq ? The U.S. military death toll in Iraq has reached 2,974, one more than the number of deaths in the Sept. 11, 2001, attacks in the United States, according to an Associated Press count on Tuesday.

The U.S. military announced the deaths of two soldiers in a bomb explosion southwest of Baghdad on Monday.

The deaths raised the number of troops killed to 2,974 since the beginning of the Iraq war in March 2003. The Sept. 11, 2001, attacks claimed 2,973 victims in New York, Washington and Pennsylvania.

“The joint patrol was conducting security operations in order to stop terrorists from placing roadside bombs in the area,” the military said in a statement on the latest deaths. “As they conducted their mission, a roadside bomb exploded near one of their vehicles.”

Another soldier was wounded in the explosion, the military said.

On Monday, British soldiers backed by tanks raided a police station in the southern city of Basra, killing seven gunmen in an effort to stop renegade Iraqi officers from executing their prisoners, the British military said.

After the British stormed the Basra police station, they removed the prisoners, who showed evidence of torture, then evacuated the building before blowing it up.

The operation showed how closely aligned some police units are with militias and death squads – and the challenges coalition forces face as they transfer authority for security to Iraqis.

In Baghdad, police found 40 bodies, apparent victims of sectarian violence. A car bomb exploded beside a market and a suicide bomber struck a bus in separate attacks that killed 14 civilians and wounded at least 33.

The Jameat police station in Basra, Iraq, is destroyed in an explosion by British troops following a raid Monday. British troops raided a police station in the southern Iraqi city of Basra after receiving intelligence that a renegade Iraqi police unit might execute its prisoners, the British military said.

In the Basra raid, the British set out to arrest officers with the station’s serious crimes unit who were suspected of involvement with Shiite death squads. Seven members of the rogue police unit were apprehended three days ago in other raids, said a British spokeswoman, Royal Navy Lt. Jenny Saleh.

“We had intelligence to indicate that the serious crimes unit would execute its prisoners in the coming days, so we decided to intervene,” Saleh said.

British troops were fired on as they approached the station and their return fire killed seven gunmen, said Maj. Charlie Burbridge, another British military spokesman.

British and Iraqi forces transferred all 76 prisoners at the station to another facility in downtown Basra, he said. Some prisoners had “classic torture injuries” such as crushed hands and feet, cigarette and electrical burns and gunshot wounds in the knees, Burbridge said.

The British demolished the building in an effort to disband the unit. “We identified the serious crimes unit as, frankly, too far gone,” Burbridge said. “We just had to get rid of it.”

The unit’s members, he alleged, were involved in tribal and political feuds in southern Iraq, which is mostly Shiite. They were not, he said, engaged in the kind of sectarian reprisal killings that have terrorized mixed neighborhoods of Baghdad.

Most of Britain’s 7,200 troops in Iraq are based in the Basra area.
