The United Nations said Wednesday that there are now more than 263,000 people internally displaced in the Gaza Strip, as Israeli airstrikes destroy buildings and homes in response to Saturday’s attack by Hamas.

That figure includes at least 137,500 people who are currently sheltering in hospitals and schools in Hamas-ruled Gaza, according to the U.N.

Israeli warplanes have struck more than "450 targets" in the Al-Furqan area in Gaza, marking the third attack in the last day, the Israel Defense Forces said in a statement early Wednesday local time.

Hamas allegedly had operations in the Al-Furqan neighborhood, and it served as a terror nest where many activities against Israel were carried out, according to the IDF.

The IDF said it will "continue to act powerfully against the infrastructures of the terrorist organization Hamas," including "extensive waves of attacks in the Gaza Strip."

Four employees of the United Nations Relief and Works Agency (UNRWA) were killed as a result of air strikes on Gaza and at least 14 of its facilities were damaged "directly and indirectly," the UN said in a release Tuesday.

According to the release, the agency was forced to close its 14 food distribution centers and reduce its operations due to the UN not being able to bring any humanitarian supplies to the Strip since Oct. 7.

There are still shops open with some supplies but Juliette Touma, director of Media and Communications for the URNWA expressed concern that basic supplies, including fuel, would run out in the next few weeks, according to the UN News.

In remarks with Israeli Prime Minister Benjamin Netanyahu, Secretary of State Antony Blinken said at least 25 Americans had now been confirmed dead in Israel.

Netanyahu described some of the atrocities committed by Hamas.

"Hamas has shown itself to be an enemy of civilization: The massacring of young people in an outdoor music festival, the butchering of entire families, the murder of parents in front of their children and the murder of children in front of their parents. The burning of people alive, the beheadings," he said.

"Hamas should be treated exactly the way ISIS was treated," he said. "They shouldn't be spit out from the community of nations. No leader should meet them. No country should harbor them. And those that do should be sanctioned."

Blinken said he was speaking not only as an American diplomat, but as a Jew, a husband and a father of young children, saying it was impossible for him to look at photos of families killed "and not think of my own children."

"The same time that we've been shocked by the depravity of Hamas, we've also been inspired by the bravery of Israel citizens," he said. "The grandfather who drove over an hour to a kibbutz under siege, armed only with a pistol and rescued his kids and grandkids. The mother who died shielding her teenage son with her body, giving her life to save his -- giving him life for a second time."

Blinken remarked that some U.S. aid had already been delivered, and that more military aid was on his way. He said the administration would work with Congress to meet Israel’s additional needs and that bipartisan support for Israel was "overwhelming."

The secretary called on world leaders to condemn Hamas.

Blinken also reiterated that Israel "has the right -- indeed, the obligation -- to defend itself" but that it was "so important to take every possible precaution to avoid harming civilians."
