Palestinian prisoners held in Israel's detention center in Huwarra near Nablus on Sunday entered the fourth day of a hunger strike, a prisoner's' society said. The Palestinian Prisoner's' Society said that prisoners in the detention center launched the strike in protest of violations carried out by Israel's prison service Violations included strip searches and poor living conditions. A lawyer from the prisoners' society who visited the Huwarra detention center said that detainees planned to continue the stroke until their demands for better conditions were met. Hunger striking -- one of the only means at their disposal -- is regularly used by Palestinian detainees to protest violations carried out inside of Israeli jails and arbitrary detention. The Knesset, Israel's parliament, approved a law in July allowing the Israel's prison service to force feed hunger strikers if their condition becomes life-threatening.
