The United States vetoed Friday a United Nations Security Council draft resolution that would have demanded an immediate humanitarian cease-fire in Gaza and the immediate and unconditional release of hostages.

Thirteen other members voted in favor of the resolution, while the United Kingdom abstained.

U.S. deputy ambassador Robert Wood told the council the resolution "was divorced from reality" and "would not move the needle forward on the ground in any concrete way" in explaining why the U.S. could not support it.

He also said the U.S. could not understand why the resolution's authors did not include language condemning "Hamas' horrific terrorist attack" against Israel on Oct. 7 and had argued an unconditional cease-fire would leave Hamas able to attack again.

The resolution, which was put forward by the United Arab Emirates, was not adopted due to the U.S. veto.

Riyad Mansour, the Palestinian U.N. ambassador, called the outcome "disastrous."

"Millions of Palestinian lives hang in the balance, every single one of them is sacred and worth saving," he said.

Israeli U.N. ambassador Gilad Erdan thanked the U.S. "for standing firmly by our side and said it was a "distorted resolution that will enable Hamas' terrorists to stay in power in Gaza."

"A ceasefire will be possible only with the return of all the hostages and the destruction of Hamas," Erdan said in a statement following the vote.

Another U.S. military aircraft landed in Egypt on Friday with 57,000 pounds of food, water and medicine to aid people in Gaza, National Security Council spokesperson John Kirby said.

"We're mindful of the extreme humanitarian suffering inside Gaza and we're doing everything we can to help alleviate that," he said.

Kirby also said the administration is "very grateful" that the Israelis agreed to open the Kerem Shalom crossing at the Israel-Gaza-Egypt border, saying it was "very much at our request" that they did so. He said it had been a point of discussion between President Joe Biden and Israeli Prime Minister Benjamin Netanyahu.

“It's good news, but we're just at the beginning of this process," he said of the Kerem Shalom crossing opening. "The first step is to set up an inspection regime, sort of akin to what's going on down in Rafah [at the Gaza-Egypt border crossing], so that the Israelis can have a measure of satisfaction that what's getting in [to Gaza] is actually what's supposed to be getting in there."

The Israel Defense Forces said it conducted a hostage rescue operation overnight in the Gaza Strip that failed to rescue any hostages.

Two IDF soldiers were severely injured in the operation while "numerous" Hamas terrorists who "took part in the abducting and holding of hostages were killed," the IDF said.

"The IDF continues to operate in a variety of operational and intelligence methods, together with security organizations, in order to release the hostages, and to collect relevant information," the IDF said.

"Civil order is breaking down in Gaza" and "society is on the brink of full-blown collapse," warned Thomas White, director of UNRWA affairs in Gaza.

"The streets feel wild, particularly after dark," White wrote Friday on X, the social media platform formerly known as Twitter.

He said some aid convoys have been looted and some U.N. vehicles were stoned.

With Gaza under "constant bombardment" and food and supplies limited, the "UNRWA’s ability to assist and protect people is reducing fast," Philippe Lazzarini, commissioner-general of the UNRWA, said in a letter to the president of the U.N. General Assembly.

“In my 35 years of work in complex emergencies, I would never have expected to write such a letter, predicting the killing of my staff and the collapse of the mandate I am expected to fulfill," Lazzarini said. "I urge all member states to take immediate actions to implement an immediate humanitarian cease-fire, enforce international law including the protection of civilians, U.N. staff, U.N. premises including shelters, medical facilities and all civilian infrastructure and protect the prospects for a political solution vital to peace and stability and the rights for Palestinians, Israelis, the region and beyond."

Israeli authorities say they have collated "hundreds of testimonies of rape and sex crimes" they claim was committed by Hamas militants during the Oct. 7 terror attack.

A document from the Israel Defense Forces details allegations of sexual violence, with "almost all of the testimonies" coming from eyewitnesses and first responders who were present at the scene during or after atrocities, the document states. This is because "virtually all" of the victims of sexual violence were also murdered on Oct. 7, according to the document.

The IDF said the document offers "only a small part of an immense body of information of evidence of Hamas' sex crimes" and said the evidence "proves beyond all doubt that Hamas and other … terrorists used rape and sexual violence systemically against Israeli women and children," according to the IDF.

One IDF volunteer quoted in the document described seeing many young women "in bloody, shredded rags, or just in underwear."

"Our team commander saw several (female) soldiers who were shot in the crotch and intimate areas," the IDF volunteer said, according to the document.

The IDF alleges that some members of Hamas who were captured and then interrogated also gave testimony that women were sexually abused on Oct. 7.

An Israeli paramedic quoted in the document said they inspected the bodies of two teenage girls who had been murdered. One of the girls "had her pants pulled down towards her knees ... and there's the remains of semen on the lower part of her back," the document states.

A survivor of the Oct. 7 attack, Gad Liebersohn, quoted in the document said that "for two hours I'm hiding and hearing people getting kidnapped and women getting raped ... begging for their lives."

Hamas, the militant group that governs the Gaza Strip, has denied the allegations that its fighters committed sexual violence during the Oct. 7 attack on neighboring southern Israel.

Cochav Elkayam-Levy, the head of Israel's Civil Commission on Oct. 7 Crimes by Hamas Against Women and Children, has described what she called "widespread rape evidence."
