Palestinians in Israeli custody
The future of Palestinians detained by Israel in the context of the Israeli–Palestinian conflict is considered central to progress in the Israeli–Palestinian peace process. Cases of prison sentences include the charges of terrorism or being a member of an "illegal terrorist organization", such as Hamas or, prior to the Oslo Accords, the Palestine Liberation Organization, but according to some accounts also the charge of political activism, such as raising a Palestinian flag.
