President Joe Biden spoke with Egyptian President Abdel Fattah El-Sisi on Friday, according to a statement from the White House.

The two leaders discussed the ongoing war and the efforts being made "to secure the release of all remaining hostages held by Hamas," according to the release.

The White House said Biden and El-Sisi spoke about a "prolonged humanitarian pause" in fighting and intensifying efforts to further increase "life-saving humanitarian assistance into and throughout Gaza."

Biden thanked El-Sisi and they agreed to continue their close coordination to increase humanitarian assistance to Gaza while setting conditions for sustainable peace in the Middle East, including the "establishment of a Palestinian state and equal measures of dignity and security for Palestinians and Israelis alike," the White House said.

Hamas has released a video of three women who are still being held in captivity in Gaza.

Shown in the video are 19-year-old Karina Ariev, 19-year-old Daniel Gilboa and 30-year-old Doron Steinbrecher, according to the Hostage Families Forum.

Ariev and Gilboa were kidnapped from the Nahal Oz kibbutz and Steinbrecher was kidnapped from the Kfar Aza kibbutz.

According to a SITE Intelligence Group translation, Ariev, addressing Israeli government officials, said in the video, "In my name and the names of all the hostages and soldiers, I ask that you get us home, stop this war, and reach an agreement. Bring us back alive. Do everything you can to get us home before we are added to the list of dead hostages. Get me home before I become a corpse."

The U.S. is expecting a "complete and thorough and transparent investigation" following allegations that 12 employees of the United Nations Relief and Works Agency for Palestine Refugees in the Near East were involved in the Oct. 7 attack on Israel, National Security Council spokesperson John Kirby said Friday.

The State Department is temporarily pausing new funding for the UNRWA in the wake of the allegations.

The Commissioner-General of UNRWA, Philippe Lazzarini, said he’s fired several staff members after Israel provided the agency "with information about the alleged involvement of several UNRWA employees" in the Oct. 7 attacks.

An investigation is underway, Lazzarini said, warning that "any UNRWA employee who was involved in acts of terror will be held accountable, including through criminal prosecution."

Earlier this month, Kirby said the UNRWA couldn't be held responsible for "the depredations of Hamas" when asked about the organization having a presence in hospitals alleged to have been used as stockpiles for weapons.

On Friday, when asked about those previous comments, Kirby noted that while there was certainly cause for concern about these allegations, "that does not and nor should it impugn the entire agency and the entire all the body of work that they're doing. ... They [UNRWA workers] have helped save literally thousands of lives in Gaza."

Sahar Amer is married with two children, ages 2 and 4, and lives in a camp in Khan Younis in southern Gaza.

"Since the beginning of the war, I have believed that this camp was safe -- a very densely populated area, and my relatives chose me as our home to seek refuge in to escape the bombing," Amer, 28, told ABC News.

"Everything has been difficult to obtain since the beginning of the war: food, water and treatment," Amer said. "But unfortunately, what happened a week ago changed everything. The area became unsafe due to the sudden entry of [Israeli] tanks behind Nasser Hospital, which is only several meters away from us."

"During the Israeli army’s incursion behind the hospital, we lived a very terrifying night due to intense artillery shelling," she said. "I could hear the sounds of bullets flying."

"Then the quadcopter planes started shooting at citizens. One time I was on the roof of the house with my children and we miraculously escaped death," Amer said.

"I did not expect the army to infiltrate in this way," she said, noting that her family "took refuge with us, believing that this area is safe and that the army cannot encircle the camp like this."

One night she headed home and said she found tanks "stationed west of the camp and surround[ing] the place."

"I felt very afraid that the tanks were approaching my house,” she said. “I was hugging my children.”

Amer wanted to leave her house, but couldn’t find a car. So she took her children and they fled on foot.

"When I approached the road, a tank appeared … and prevented us from passing through,” she said. "I returned home crying and afraid that our fate will be death like the residents of other areas. I sent a message to my mother and sister to pray for me to be saved."

"I went out with great difficulty the next day. I left my home crying. I do not want to be displaced -- I want to remain safe in my home." she said. "I hope the war will end -- there is enough death and destruction."
