A report released Tuesday by a human rights group details allegations of horrific torture and abuse at a secret prison in Iraq where detainees say they were routinely beaten, shocked and sodomized by their interrogators.
The report by Human Rights Watch was based on interviews conducted Monday with 42 prisoners who had been held at a secret facility in west Baghdad's old Muthanna airport since late 2009.
The men were among 300 detainees who were transferred in recent weeks to another detention center after the existence of the Muthanna prison was revealed, Human Rights Watch said.
Allegations of torture and abuse at Muthanna were first reported by The Los Angeles Times on April 19. Amnesty International has urged Iraqi officials to investigate the claims.
CNN could not immediately reach U.S. or Iraqi officials for comment on the Human Rights Watch report Tuesday.
