Since the first Palestinian uprising began in 1987 the vast majority of security prisoners held in Israel have always been Palestinians. According to official figures supplied to the Israeli human rights organisation B'Tselem, 9,153 Palestinians are currently held by civilian and military authorities.
Of those, B'Tselem says 8,085 are held in civilian jails, 2,384 of them without charge. Some 645 are held under "administrative detention", without charge and often without knowledge of the suspicions against them. Among those in civil jails are 74 women and 265 under-18s.[url][/url]
