Conditions at Policharki prison’s Block D, where prisoners transferred from US custody in Guantánamo Bay and at Bagram Air Force Base are housed, are some of the very best in Afghanistan.

Files on the men collated by the US military are given to Afghan authorities when the prisoners transfer to Afghan custody. These are reviewed by a special court inside the prison.
