The Defense Department has identified six military personnel killed last week in combat or in accidents or other noncombat reasons in Iraq.

— Spc. Richard P. Orengo, 32, of Puerto Rico, was shot and killed Thursday. Orengo, a member of the 755th Military Police Company, Arecibo, Puerto Rico, apparently was the soldier whom the U.S. Central Command said was fatally shot while investigating a car theft Thursday in Najaf, 100 miles southwest of Baghdad.

— Spc. Andrew F. Chris, 25, of California, was killed Wednesday "in combat operations in hostile enemy territory," the Pentagon said. It did not explain where the territory was. Chris was assigned to Company B, 3rd Battalion, 75th Ranger Regiment, Fort Benning, Ga.

At least 61 U.S. troops have died in at least 23 attacks in Iraq since President Bush declared that major combat was over May 1.

These servicemen's deaths were not in combat:

The Pentagon also identified these deaths during the week from other areas of the region:
