A former detainee at the notorious Abu Ghraib prison in Iraq recounts the horror and pain of his incarceration two decades after the war.

Berlin, Germany – It was snowing and the roads were empty on an early Saturday. The dread was, is it really him? Will he agree to speak?

We arrived at his apartment and were greeted by a friend who took us up. He introduces himself in smart attire. Meet Ali Shallal al-Qaysi, the man under the hood of the torture photos from the infamous Abu Ghraib prison.

He takes me to the kitchen and whispers as we set up for the TV interview in the other room – some details are too gruesome and painful to recount. I assure him, it is his story and I will listen to what he has to tell us. What ensues in the next couple of hours is not for the faint-hearted. His stories paint a horrific picture of inhumane abuse, humiliation, torture and sadistic behaviour.
