50 Palestinian prisoners held in Nafha Israeli prison, Mitzepe Ramon, will start an open-ended hunger strike on Sunday in support of the hunger striking administrative detainees, who also threatened to escalate their hunger strike and stop drinking water, according to the Palestinian Prisoner’s Club (PPC) and an activist.WAFA reports that the PPC said 50 prisoners will join the open-ended hunger strike in solidarity with the administrative detainees, who have been on an open-ended hunger strike for 29 consecutive days protesting their detention without charge or trial.

Meanwhile, hunger strikers have threatened to escalate their demonstration and stop drinking water, in an attempt to get prisons administration to recognize their demands and end their administrative detention, by which they are held without charge or trial.

Prisoners have boycotted clinics, refrained from taking salt and dietary supplements, and now rely on water only, according to attorney Mona Naddaf, of Addameer Human Rights association.

In 2012, Israel made a promise to put limits on the policy, in an agreement which ended the strike of 2,000 Palestinian prisoners, but as of March 1, 183 Palestinians were still being held under administrative detention.

At the beginning of May, the vast majority of more than 5,000 Palestinian prisoners being held in Israeli prisons began taking part in a solidarity strike with the prisoners who have been refusing food since April 24.

Health conditions of the hunger strikers are deteriorating, with some close to death.
