The US prison camp at Guantanamo Bay was disorganised and dysfunctional in its early years, documents released under a Freedom of Information Act lawsuit have shown.
The first commander of the detention centre in Cuba said in the documents that US interrogators had practically no experience, while the military linguists "were worthless".
Clara Gutteridge from Reprieve International, an organisation campaigning for the fair treatment of prisoners, said the documents confirmed previous knowledge about the "systematic nature of abuse at Guantanamo Bay".
