State Department Cable re: Repatriated Russian Guantanamo Detainees Released by Russian Procuracy. The seven Russian detainees from the Guantanamo military base that were previously handed over by the United States to the Russian Government have been released from custody by an order of the Russian General Procuracy. While the circumstances surrounding their release remain under investigation, there is nothing the U.S. can do about the release. Once release, the detainees were returned to Russia. Upon arrival in Moscow, they were taken into custody by Russian law enforcement officials and charged with belonging to an organized criminal group, the illegal crossing of a state border, and "mercenary activity", but were subsequently released.
