Hospitals in the Gaza Strip have been overstretched by the more than 2,700 people injured along Israel's border fence, including 1,300 by gun fire, UN agencies said in Geneva.
World Health Organization (WHO) spokesman Tarik Jasarevic said that Israel's long-lasting blockade of the Gaza Strip had created chronic shortages in Palestinian health facilities.
"This month, two in every five essential drugs are completely depleted and half have less than a month's supply remaining," he told a press conference.
Gaza's public hospitals have less than a week of fuel supplies left to keep operating, spokesman Jens Laerke of the UN emergency aid agency OCHA said.
