The Palestinian Central Bureau of Statistics says more than 7,000 Palestinians are currently held under life-threatening conditions in Israeli prisons.
In the run up to the Palestinian Prisoners Day, scheduled for Saturday, the office issued a statement in which it condemned the continued detention of 34 Palestinian women and 270 child prisoners.
Three of the prisoners have been in jail for more than three decades, and 315 for more than 15 years, said the Thursday statement.
According to the bureau, Israel has arrested more than 760,000 Palestinians since the occupation of the Palestinian territories in 1967, including 70,000 arrests made following the al-Aqsa Intifada in 2000.
The data also indicates that more than 19,000 Palestinian have been detained under administrative terms — detention without trial — over the past eight years, 264 of whom are currently held in Israeli prisons.
Meanwhile, 1,000 people are still awaiting trial.
Since 1967, at least 200 Palestinian prisoners have been killed in Israeli detention and interrogation centers. These prisoners are subjected to inhuman treatment such as torture, deprivation of medical treatment, years-long isolated confinement and deliberate killing.
