Coded letters from Briton in Guantanamo Bay reveal 'regime of violence'

• Prisoner Martin Mubanga is using a mixture of slang and patois in his letters home to describe the conditions in Camp Delta.

Serious new allegations about the ill-treatment of prisoners at Guantanamo Bay have been revealed in a series of letters from a British detainee, who has accused US guards of threatening him with sexual assault and physical violence, The Independent on Sunday can reveal. The letters from Martin Mubanga, one of the last remaining British detainees in Guantanamo Bay, were carefully written to escape the military censors, using a unique mixture of London street slang, Cockney, Jamaican patois and rap lyrics. In his letters home to his younger brother Anthony - all stamped "cleared by US Forces" - he talks about "radix", slang for the authorities or police, and about the "bull boy" guards "giving it large", a reference, his family says, to threats and the use of violence. Other passages accuse the guards of threatening him with sexual abuse: "expecting man n' man to bend over so as them there can give to man n' man real good." [more]
