Several dozen Palestinians on hunger strike, protesting Israel's use of administrative detention to keep them behind bars, have been taken to hospital.
"The Secretary-General is concerned about reports regarding the deteriorating health of Palestinian administrative detainees who have been on hunger strike for over a month," U.N. spokesman Stephane Dujarric told reporters.
"He reiterates his long-standing position that administrative detainees should be charged or released without delay," he said.
Israel's Prisons Service said 65 Palestinian hunger-striking prisoners were in hospitals, though none was in critical condition and all were conscious. The Palestinians put the number of prisoners who had required hospital care at 78.
