A member of the Jehovah's Witnesses serving a seven-year sentence in a Russian prison for practicing his faith was recently tortured for information about other members of the church, according to the Christian denomination.

Rinat Kiramov, 36, says he's been punched, bound, tased, waterboarded and deprived of food and sleep by fellow prisoners demanding that he give them names of Jehovah's Witnesses in his city of Akhtubinsk, located in southwestern Russia near the border with Kazakhstan, according to the Christian denomination.
