Abdul Shakoor Dadras, a member of the Criminal Cases Review Commission said, around 764 cases of the prisoners were reviewed by the commission during the past nine months.
Mr. Dadras further added that the commission found no satisfactory evidence against the 650 prisoners, and were released from the jail.
Meanwhile, Dadras said that the commission has referred 114 cases to the Attorney General Office of Afghanistan for further process.
The commission to review the cases of Bagram prisoners, was formed based on a presidential decree earlier this year, after Bagram prison was transferred to the government of Afghanistan.
The responsibilities of US-run Bagram prison was handed over to the Afghan government late in March this year, after Kabul and Washington reached a deal for the transfer the detention facility to Afghan control.
Transfer of Bagram prison where nearly 3,000 suspected Taliban and al-Qaida operatives were held, was a source of tension between Afghanistan and the United States.
The transfer had been delayed several times over the past couple of years, with US officials citing thorny issues such as whether Afghans can be held without trial and whether the U.S. will have the power to block the release of detainees it considers particularly dangerous.
However, the prison was transferred after Afghan government offered “private assurances” that detainees whom the United States considers to be most dangerous would not be released.
