The former United States commander at Baghdad's Abu Ghraib prison says the outgoing US Defence Secretary Donald Rumsfeld, authorised the mistreatment of detainees at the prison.
Former US Army Brigadier-General Janis Karpinski, who ran the prison until early 2004, says she has seen a letter apparently signed by Mr Rumsfeld that allowed civilian contractors to use techniques such as sleep deprivation during interrogation.
She says she saw a memorandum signed by Mr Rumsfeld detailing the use of harsh interrogation methods.
A spokesman for the Pentagon declined to comment.
Don't worry Mr Spokesman, we have ways of making you talk - ask the geriatric Hicksville thug.
