The U.S. military has announced charges against eight service members in connection with the death of an Iraqi civilian.

Marine Colonel Stewart Navarre said Wednesday the eight face charges including kidnapping, murder and conspiracy.

The seven Marines and a Navy corpsman are suspected of killing an Iraqi man without provocation in the village of Hamdania in April. They have been held since May at Camp Pendleton, California.

Four other Marines not being held remain under investigation.

The investigation is separate from the probe of the events of Haditha in November 2005, in which Marines are alleged to have killed 24 Iraqi civilians after a roadside bomb blast in the town killed a fellow Marine.
