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.

Dozens of fighter jets attacked more than 70 targets in a neighborhood in the Gaza Strip, the Israel Defense Forces said.

Hamas allegedly had operations in the neighborhood and carried out activities against Israel, according to the IDF.

The IDF said it also attacked a military building that was allegedly used by the Islamic Jihad terrorist organization.

The World Health Organization repeated its call to end hostilities in the Israel-Gaza region and offered assistance to health officials in both countries.

Egyptian President Abdel Fattah El-Sisi agreed to a WHO request to facilitate the delivery of health and other humanitarian supplies from WHO to Gaza via the Rafah crossing, the organization said.

"In the Gaza Strip, hospitals are running on back-up generators with fuel likely to run out in the coming days. They have exhausted the supplies WHO pre-positioned before the escalation," the organization said in a statement. "The life-saving health response is now dependent on getting new supplies and fuel to health care facilities as fast as possible."

Former Israeli Foreign Minister and former Knesset member Tzipi Livni spoke with ABC News Live about the recent Hamas attacks on Israel and argued the group is "not just an Israeli problem."

Livni said, "Hamas was always an obstacle to peace," and called on the entire international community to stand against them.

"They don't represent the Palestinian people," Livni said about Hamas. "They represent this extreme religious ideology that does not accept not only Israel, [but also] the U.S., or our liberal values, [and] democratic ideas."

She thanked President Joe Biden for his support of Israel shortly after he delivered remarks, and said that for Israelis listening it was "the first light in dark days."
