Human Rights Watch issued a report Tuesday that says Iraqi forces linked to Prime Minister Maliki are running a secret prison for terror suspects.
A new Amnesty International report on Iraq estimates that 30,000 untried detainees are currently being held by Iraqi authorities, many of them transferred from US prisons.
Despite the Abu Ghraib scandal, US troops are now seen as protectors of human rights. Iraqis say they are being tortured in Iraqi secret prisons.
As the Iraq election process is drawn out by a recount, Prime Minister Nouri al-Maliki faces a fresh challenge over allegations of torture on his watch. He dismissed an HRW report, saying detainees bruised themselves to fake torture evidence.
As the US speeds the transfer of detainees in its custody, many appear headed into a notoriously violent system. Inmates at Abu Ghraib rioted Thursday and Friday.
