The Gaza Strip was illuminated by flares and explosions early Monday as Israel persisted with its intense military campaign.
More than two-thirds of Gaza’s population of 2.3 million have fled their homes after Israel declared war against Hamas in the territory.
The UN agency for Palestinian refugees, or UNRWA, is struggling to provide basic services to hundreds of thousands of displaced people.
Seventeen of its facilities have been directly hit, the agency said.

At least 12,000 Palestinians, including at least 5,500 children, have been killed in Israeli airstrikes, according to Palestinian health authorities.

A further 2,700 have been reported missing, believed buried under rubble.
The level of violence ravaging Gaza in recent days is unfathomable, the UN rights chief said Sunday, with attacks on schools harboring displaced people and a hospital turned into a “death zone.”

“The horrendous events of the past 48 hours in Gaza beggar belief,” United Nations High Commissioner for Human Rights Volker Turk said in a statement.
He spoke as the World Health Organization scrambled to evacuate the last remaining patients and staff from the Al-Shifa Hospital, with UN officials describing the Palestinian territory’s largest health facility, raided last week by Israeli troops, as a “death zone.”

Elsewhere in northern Gaza, a Hamas health official said more than 80 people were killed on Saturday in twin strikes on Jabalia refugee camp, including on a UN school sheltering displaced people.

“The killing of so many people at schools turned shelters, hundreds fleeing for their lives from Al-Shifa Hospital, amid continuing displacement of hundreds of thousands in southern Gaza, are actions which fly in the face of the basic protections civilians must be afforded under international law,” Turk said.

He described the images purportedly taken in the aftermath of the reported Israeli strike on the UN-run Al-Fakhura school as “horrifying,” and “clearly showing large numbers of women, children and men severely wounded or killed.”
