"There was a machine designed for shredding plastic. Men were dropped into it and we were again made to watch. Sometimes they went in head first and died quickly. Sometimes they went in feet first and died screaming. It was horrible. I saw 30 people die like this. Their remains would be placed in plastic bags and we were told they would be used as fish food . . . on one occasion, I saw Qusay [President Saddam Hussein's youngest son] personally supervise these murders."
