Israeli forces arrested large numbers of people inside Nasser Hospital in Khan Younis, as Israel’s multiday raid of the complex — the main hospital in southern Gaza — continues into its third day.

The Israel Defense Forces said early Saturday that its troops arrested about 100 people “suspected of terrorist activity” inside the hospital and killed “terrorists around the area of the hospital.” Gaza’s Health Ministry said the IDF had “arrested a large number of medical staff from inside the Nasser Medical Complex, which it has turned into a military barracks.”

Gaza health officials said Friday that five intensive care patients had died because of a lack of oxygen, after the complex was left without electricity or water during the raid.

The U.N. human rights office has expressed deep concern over the raid, saying it came “after a week-long siege which cut off medical, food and fuel supplies” to the complex, and appeared “to be part of a pattern of attacks by Israeli forces striking essential life-saving civilian infrastructure in Gaza, especially hospitals.”

Israeli troops entered the complex Thursday, after issuing evacuation warnings for the hospital, where more than 5,000 people were sheltering the day before. At the time, they said they had credible intelligence that the bodies of hostages could be held at the hospital.

No hostage bodies have been recovered so far, but the IDF said it had recovered weapons and medications with the names of Israeli hostages within the complex. On Saturday, it said its activities at the hospital were based on intelligence indicating that Hamas was carrying out military activity there.

In a separate statement to The Washington Post on Saturday, the IDF also said it was “well documented that Hamas uses hospitals and medical centers for its terror activities.” International doctors volunteering there have said they saw no sign of militant activity on the premises, and critics have said Israel’s hospital raids have been disproportionate to any threat posed by militants who may have been operating there.

Here’s what else to know

• Twenty-two of Gaza’s 36 health facilities are not functioning at all, the World Health Organization confirmed to The Washington Post in an email Saturday, while 11 others are only partially functioning.

• New York Gov. Kathy Hochul came under criticism after appearing to imply that Israel had justification to destroy Gaza this week. “If Canada someday ever attacked Buffalo, I’m sorry, my friends, there would be no Canada the next day,” Hochul said during a speech to a Jewish philanthropy event in New York on Thursday, before going on to say: “That’s a natural reaction.” She later apologized for a “poor choice of words,” saying in a statement that she regretted “using an inappropriate analogy that I now realize could be hurtful to members of our community.”

• The International Court of Justice on Friday declined South Africa’s request to introduce additional safeguards for Palestinians ahead of Israel’s planned offensive in the southern city of Rafah, where an estimated 1.4 million Palestinians are seeking refuge from Israeli bombardment. Instead, the ICJ said the “perilous situation” in Rafah required Israel to abide by its previous ruling last month, which included taking “all measures within its power” to prevent the crime of genocide and to allow more aid into Gaza. South Africa is pursuing a case against Israel in the ICJ, alleging it is committing and failing to prevent genocide in Gaza, accusations that Israel denies.

• The situation in Rafah is becoming increasingly dire, according to the U.N. humanitarian office, with people “desperate, hungry, and terrified” ahead of Israel’s anticipated attack. The office also said the number of aid trucks allowed to enter Gaza had declined drastically over the past week. President Biden told Netanyahu last week that the assault should not proceed without a “credible and executable plan” to protect civilians in Rafah. On Friday, Biden said he had pushed the Israeli leader over recent days to accept a temporary cease-fire in Gaza to allow the release of the remaining hostages.

• A U.N. relief worker is said to have appeared on video removing an Israeli man’s body after he was shot at Kibbutz Beeri on Oct. 7, according to a Post analysis of information released by Israeli authorities.

• Israel has expanded its allegations against the U.N. Relief and Works Agency, asserting there are “significant indications” that more than 30 UNRWA workers were involved on Oct. 7. UNRWA spokesman Jonathan Fowler said Israel did not detect that attack in advance, “implying that all involved … participated illicitly in ways that UNRWA also would have been unable to detect.”

• Egyptian and Israeli officials denied speculation that Palestinian refugees would be pushed out of Rafah and into Egypt, after satellite imagery obtained by The Post showed Egypt clearing and building a wall around a plot of land along its border with Gaza. “The State of Israel has no intention of evacuating Palestinian civilians to Egypt,” Israel’s defense minister said.

• At least 28,858 people have been killed and 68,677 injured in Gaza since the war began, according to the Gaza Health Ministry. Israel estimates about 1,200 people were killed in Hamas’s Oct. 7 attack and says at least 235 of its troops have been killed since its offensive in Gaza began.
