At least 274 people were killed and another 698 were injured during Saturday’s Israeli rescue operation that saved four hostages from Hamas custody in Gaza, according to Gaza’s Hamas-controlled Ministry of Health.

Israeli special forces were disguised as Palestinian refugees looking for a place to live when they entered the buildings where hostages were being held in the rescue operation, two Israeli security sources told ABC News.

The hostages were rescued from two locations in Nuseirat, a camp that has become home to thousands of refugees who've fled fighting throughout Gaza.

The United Nations Security Council on Monday adopted a U.S. draft resolution urging Hamas to accept the latest cease-fire and hostage release deal.

Nate Evans, spokesperson for the U.S. mission to the United Nations, said in a statement ahead of the vote that the deal would enable a pause in fighting, the freeing of a number of hostages and an immediate surge in humanitarian assistance, among other things.

"Israel has accepted this proposal and the Security Council has an opportunity to speak with one voice and call on Hamas to do the same," Evans said. "Doing so would help save lives and the suffering of civilians in Gaza as well as the hostages and their families. Council Members should not let this opportunity pass by and must speak with one voice in support of this deal."

U.S. Ambassador Linda Thomas-Greenfield made a similar case just before the vote, saying every day the war goes on "needless suffering continues."

"Colleagues, after eight months of devastation and pain and trauma, what is needed now more than ever is for the fighting to end in a sustainable way," she said. "The United States and every single country in this chamber wants to see an immediate cease-fire with the release of hostages. We've heard those calls time and time again since Oct. 7. Now the opportunity is here. We must seize it."

Hamas said in a statement they "welcome" what was included in the U.N. Security Council resolution "regarding a permanent cease-fire in Gaza."

Israeli special forces were disguised as Palestinian refugees looking for a place to live when they entered the buildings where hostages were being held in the Israeli rescue operation this weekend, two Israeli security sources told ABC News.

Special forces were already in position near the buildings where the hostages were being held before they were given the "go" command by Israeli forces, the sources added.

The "go" command was given at 11 a.m. local time, sources said.

The helicopters carrying the hostages and wounded police officers landed at Sheba Medical Center in Israel starting at 12:15 p.m. local time and the last helicopter landed at 12:45 p.m. local time.

The Shin Bet, Israel's internal security forces, Israeli Defense Forces and Israeli SWAT team members participated in the rescue operation, now called "Operation Arnon" by the Israeli military. The name of the operation was given to honor the one security officer who was killed during the operation.
