U.S. and Iraqi officials have announced a broad inquiry into prison conditions at detention centers across the country. The announcement follows the discovery Sunday of over 170 prisoners in the basement of an Interior Ministry compound. Iraqi officials insisted Thursday no more than seven detainees showed signs of torture. But the US government-run Voice of America broadcast service says at least a third of the detainees: “appeared severely emaciated and many showed cuts and bruises on their faces, arms and legs.” One man was taken out of the compound on a stretcher because he was unable to walk. The detainees were transferred to the US-run Abu Ghraib prison.
