More than 630,000 people have fled Rafah since May 6 amid widening operations by Israel’s military, with many seeking refuge in Al-Mawasi and Deir al-Balah -- areas overcrowded with "dire conditions" -- according to the United Nations.

Humanitarian assistance shipments delivered to Gaza through the U.S.’ maritime corridor should not replace aid coming into the enclave through land crossings where "barely 100 trucks of aid a day" entered over the last two weeks -- about a sixth of the level needed to stave off famine -- USAID Administrator Samantha Power said in a statement Friday.

"Every moment that a crossing is not open, that trucks are not moving, or where aid cannot safely be distributed, increases the terrible human costs of this conflict," Power said.

Supplies coming into Gaza through the temporary pier Friday include contributions from the U.S., United Arab Emirates and the United Kingdom.

But, the statement doesn’t say how much aid is now being moved through the corridor at this point or how much of it is sitting in Cyprus waiting to be shipped -- so it’s still unclear if and when these deliveries might have a substantial impact.

Almost 1,400 buildings have likely been damaged or destroyed in Rafah, Gaza, since May 4, according to an analysis of satellite imagery by two university researchers.

Data from the radar-enabled Copernicus Sentinel-1 satellite operated by the European Space Agency was used to analyze the effects of fighting on the terrain and buildings of Gaza, according to Corey Scher, of the CUNY Graduate Center, and Jamon Van Den Hoek, of Oregon State University.

Between May 4 and May 8, the researchers found evidence that 895 buildings were likely damaged or destroyed in Rafah. From May 8 to May 16 they counted 487.

Since Oct. 5, the researchers have found evidence of likely damage or destruction to 18,176 of the 48,678 buildings in Rafah.

The bodies of three hostages have been recovered, according to the Israel Defense Forces. The bodies of Shani Louk, 23, Yitzhak Gelanter, 57, and Amit Buskila, 28, were recovered in an operation by the Shin Bet, Israel's security agency.

The hostages had escaped from the Nova Music Festival and were killed in the area of ​​Kibbutz Mefalsim and their bodies were taken to Gaza, according to the IDF. Louk's capture generated international headlines after video emerged of her lifeless body in the back of a truck with Hamas terrorists.

"Our hearts go out to them, to the families, at this difficult time and we will leave no stone unturned, we will do everything in our power to find our hostages and bring them home," Rear Adm. Daniel Hagari, spokesperson for the IDF, said. "We will not rest until we do."

Israel Defense Forces released Sunday raw video footage it says its troops recovered in Gaza that shows former Israeli hostages 8-year-old Ela Elyakim and her 15-year-old sister Dafna Elyakim being forced by Hamas terrorists to film repeatedly.

"The video, which is being released today for the first time was intended to be used by Hamas for psychological terror," Rear Adm. Daniel Hagari, an IDF spokesperson, said in a statement. "But Ela’s family asked us to share it with the world to expose Hamas's terror, to expose Hamas's cruelty, to expose Hamas's barbarism."

Hagari said the raw footage of the girls recording the video was recovered by IDF troops during Israel's ground operations in Gaza.

The Elyakim sisters were kidnapped on Oct. 7 from their father's house in Nahal Oz, according to the IDF. Their father was killed in the surprise attack on Israel by Hamas terrorists, according to the IDF.

Ela and Dafana Elyakim were held hostage for 51 days before Hamas released them in a previous hostage deal, the IDF said.

Ela Elyakim told IDF officials that Hamas terrorists forced her to read from a script and made her change clothes multiple times as they refilmed the video over and over, according to Hagari.

"We will continue doing everything in our power to bring our hostages back home," said Hagari.
