Jassim's brother, who was wounded by broken glass, said he did not see any warnings as he sped his sister to the hospital. Her husband was waiting for her there.

"I was driving my car at full speed because I did not see any sign or warning from the Americans. It was not until they shot the two bullets that killed my sister and cousin that I stopped," he said. "God take revenge on the Americans and those who brought them here. They have no regard for our lives."

He said doctors tried but failed to save the baby after his sister was brought to the hospital.

The shooting deaths occurred in the wake of an investigation into allegations that U.S. Marines killed unarmed civilians in the western city of Haditha.
