Mr al-Baz claims the guards at the prison were keen to take photographs of the abuse and turned it into a competition.
"They were enjoying taking photographs of the torture. There was a daily competition to see who could take the most gruesome picture.
"The winner's photo would be stuck on a wall and also put on their laptop computers as a screensaver.
"I had a good opinion of the Americans but since my time in prison, I've changed my mind. In Iraq we still have no freedom or democracy. They are so cruel to us."
