A former prisoner held at Guantanamo Bay says he was never interrogated about the reason the US said they’d arrested him for — even after seven years in captivity.

He also provided a graphic account of new elements of what may be considered “ad-lib” torture — guards inappropriately using hypodermic needles and IV tubes intended for forced feeding during hunger strikes.

“I don’t think. I’m sure,” he replied.
