Participants in a contentious Baghdad security operation this month have told American investigators that during the operation at least one guard continued firing on civilians while colleagues urgently called for a cease-fire. At least one guard apparently also drew a weapon on a fellow guard who did not stop shooting, an American official said.
The operation, by the private firm Blackwater USA, began as a mission to evacuate senior American officials after an explosion near where they were meeting, several officials said. Some officials have questioned the wisdom of evacuating the Americans from a secure compound, saying the area should instead have been locked down.
These new details of the episode on Sept. 16, in which at least eight civilians were killed, including a woman and an infant, were provided by an American official who was briefed on the American investigation by someone who helped conduct it, and by Americans who had spoken directly with two guards involved in the episode. Their accounts were broadly consistent.
A spokeswoman for Blackwater, Anne E. Tyrrell, said she could not confirm any of the details provided by the Americans.
