RAMALLAH (Ma’an) – Five Palestinians are currently on a hunger strike in Israeli prisons to protest solitary confinement and Israel’s policy of administrative detention — internment without charge or trial.Amjad al-Najjar, the director of the Palestinian Prisoner’s Society’s office in Hebron, said in a press statement on Saturday that prisoner Sami Janazrah has been on hunger strike since March 3, Imad al-Batran started his strike since March 15, and Abd-al-Rahim since March 24, all in protest of administrative detention.They were joined in their strike Saturday by Zayid al-Basisi who is sentenced to life plus 55 years, and Nahar al-Sadi, who was sentenced to four life sentences plus 20 years. They are both protesting solitary confinement.The Palestinian Prisoner’s Society called for a sit-in in front of the International Red Cross building in Hebron this coming Monday in support of the hunger strikers.A report released this month by Physicians for Human Rights – Israel revealed that placements in solitary confinement in Israel’s prisons doubled from 2012 to 2014.Imprisoned Palestinian journalist Muhammad al-Qiq last month ended a grueling 94-day hunger strike that brought him close to death after his lawyers struck an eleventh hour deal with Israeli authorities.He initially went on hunger strike in November to protest the torture and ill-treatment he said he faced in Israeli custody, but his protest quickly developed into another bid to challenge Israel’s use of administrative detention.According to prisoners’ rights organization Addameer, 670 Palestinians are currently held under administrative detention by Israel, a policy the international community has repeatedly said is used by Israel in contravention to international law.
