BAGHDAD, Iraq (AP) Four Iraqis suspected of killing a pair of American officials and their translator appear to be active police officers working with a Saddam Hussein loyalist, a top U.S. military official said Friday, raising concerns that insurgents are infiltrating Iraqi security forces being trained by U.S. forces.
The four were caught along with a former officer from the Saddam-era police forces and a civilian after the slayings Tuesday of the two U.S.-led coalition staffers and an Iraqi woman south of Baghdad, Maj. Gen. Mark Kimmitt said.
U.S. troops have been setting up Iraqi police and other security forces, intending to gradually put them on the frontlines against guerrillas.
