The top United Nations human rights official urged Israel on Wednesday to improve conditions for Palestinians security prisoners, especially the more than 1,000 whose hunger-strike was into its 38th day.
The strike followed a call by Marwan Barghouti, the most high-profile Palestinian terrorist held by Israel, for a protest against solitary confinement and an Israeli policy of detention without trial that has been applied to thousands of prisoners since the 1980s.
"I am especially alarmed by reports of punitive measures by the Israeli authorities against the hunger strikers, including restricted access to lawyers and the denial of family visits," Zeid Ra'ad al-Hussein, UN High Commissioner for Human Rights, said in a statement.
The right to consult a lawyer is a fundamental protection in international human rights law that should never be violated, Zeid said. He added that the health of hundreds of the hunger-strikers had "deteriorated significantly."
While hunger strikes are not uncommon among the 6,500 Palestinians in Israeli jails, many of whom were convicted of attacks or planning attacks against Israel, this is one of the largest.
It is likely to raise tensions between Israel and the Palestinians as the 50th anniversary of the Six-Day War, during which Israel captured the West Bank and east Jerusalem, approaches in early June.
Zeid said his office had received reports that the Israel Prison Service had evacuated at least 60 hunger-striking Palestinian prisoners to hospitals because their medical condition had worsened. A further 592 had recently been moved for observation to infirmaries set up in the prisons, he said.
The International Committee of the Red Cross (ICRC), which visits Palestinian detainees, urged Israel early this month to allow family visits. Under international law, these "can only be limited for security reasons, on a case by case basis, but never for strictly punitive or disciplinary purposes," it said.
It added that "Israel detains Palestinians within its territory—but not within the occupied territory as required by the law of occupation."
