Some 9,700 Palestinian security detainees were being held captive in Israeli prisons in May, according to Addameer, a Palestinian prisoner rights organization. Some 3,380 were administrative detainees, meaning Israel holds them without charge or trial.

The numbers do not include prisoners from Gaza. The Post reports that Israeli authorities will not reveal exactly how many have been detained or where they are held.
