As many as 71 Palestinian prisoners have died in Israeli jails as a result of torture since 1967, Abdel Nasser Farwana, head of the documentation and studies unit at the detainees and ex-detainees committee, said.
In a statement released on Sunday to mark the International Day Against Torture, Farwana said dozens others died shortly after being released as an effect of the torture they had endured, adding that many more suffer from long-term physical and psychological disabilities.
"Israel practices a unique and atypical form of physical and psychological torture and it is the only country in the world that legalises torture in its jails and detention camps and protects its perpetrators," he explained.
"Israel uses torture on institutional level against Palestinian and Arab detainees. According to our data, 100 per cent of the Palestinian prisoners were subjected to one form or another of torture," he added.
Farwana called on international institutions and human rights organisations to take serious and effective steps to stop all forms of torture against Palestinian prisoners and to prosecute those who practice torture against them.
