A newly released prisoner from Guantanamo Bay has accused US officials of torturing him and beating him dozens of times at a secret CIA prison and later at Guantanamo. The Ethiopian-born Binyam Mohamed returned to Britain on Monday after becoming the first Guantanamo prisoner freed under President Obama. In a statement read by his attorney, Clive Stafford Smith, Mohamed called for his captors and jailers to be held accountable.

Clive Stafford Smith: “For myself, the very worst moment came when I realized in Morocco that the people who were torturing me were receiving questions and materials from British intelligence. I had met with British intelligence in Pakistan. I had been open with them. Yet the very people who I had hoped would come to my rescue, I later realized, had allied themselves with my abusers. I am not asking for vengeance, only that the truth should be made known so that nobody in the future should have to endure what I have endured.”

Mohamed was arrested in Pakistan in 2002 and taken to Morocco and Afghanistan before going on to spend more than four years at Guantanamo Bay.
