The World Health Organization (WHO) on Tuesday called for a humanitarian corridor into the Gaza Strip as Israel imposes a siege on the blockaded Palestinian enclave.
A WHO spokesperson said it had reported 13 attacks on health facilities in Gaza since the weekend.
Nearly 200,000 people, or nearly a tenth of the population, have fled their homes in the Gaza Strip since the start of hostilities, said the UN's human rights office, warning that the enclave is poised for water and electricity shortages due to an Israeli blockade.
"Displacement has escalated dramatically across the Gaza Strip, reaching more than 187,500 people since Saturday. Most are taking shelter in schools," Jens Laerke, OCHA spokesperson, told a Geneva briefing, saying further displacement was expected.
Israeli air operations have struck residential buildings, including large tower blocks, as well as schools and UN buildings across Gaza, resulting in civilian casualties, the United Nations Human Rights chief said on Tuesday, citing information gathered by his office.
"International humanitarian law is clear: the obligation to take constant care to spare the civilian population and civilian objects remains applicable throughout the attacks," Volker Turk said in a statement.
In response to Israeli Defense Minister Yoav Gallant's announcement of a tightened blockade for the Gaza strip, Turk said that "sieges" that endanger the lives of civilians are prohibited under international law.
