Suddenly and without warning, Mr. Adnan said, a United States military vehicle opened fire, putting several rounds through his Nissan pickup truck. Mr. Adnan was wounded in the shoulder and suffered cuts to his face from windshield glass. The other two vehicles pulled off more quickly, across the highway and just in front of the hospital, he said.
The American troops then began to concentrate fire on the two vehicles that had stopped in front of the hospital, Mr. Adnan said. As the Iraqi officers shouted, in English, "Police! Police!" the American soldiers responded, "No police!" and continued firing, he said. One volunteer police officer held up a badge with his force's insignia, but the soldiers shot and killed him anyway, Mr. Adnan said.
one of the Iraqi soldiers fired their weapons, Mr. Adnan said. Mr. Jassim, the commander of the force, said he had been invited to the American base to pick up the bodies of the dead officers and had seen their rifles. In every case, the guns had their safeties on, Mr. Jassim said.
Wesam Mahmoud, another Iraqi officer who was in the truck driven by Mr. Adnan, corroborated Mr. Adnan's story. "The Americans stepped back and started shooting at us," he said.
The description of the shooting by Mr. Adnan and Mr. Mahmoud also closely matched that offered by Abdul Jalil, a member of the Fallujah volunteer police who was also wounded in the shootout.
Mr. Jalil, who was in a truck that was one of the two vehicles stopped in front of the hospital, said on Friday that American troops had fired from close range at his truck even though the Iraqis had desperately shouted, "Police! Police!" Eight of the 10 men in Mr. Jalil's truck died, along with two of the five in the Iraqi police car near it, according to the officers.
