U.S. officials shared an update Thursday on efforts to bring aid into Gaza through the Army's Joint Logistics Over-the-Shore (JLOTS) system, a floating pier built to transport aid to the region.

Since Friday, over 506 metric tons of aid have been transported via the pier, according to officials.

Officials from U.S. Central Command (CENTCOM) and the U.S. Agency for International Development (USAID) held an audio-only briefing with reporters on continued aid efforts.

"Since the first shipments of this aid arrived through the humanitarian maritime corridor on Friday, the UN has been distributing more than 506 metric tons of humanitarian supplies to people in need," Daniel Dieckhaus, Director for USAID’s Levant Response Management Team, said Thursday.

"To put it into perspective, more than two thirds of the supplies entering through this new corridor have already been distributed, or are in the process of being distributed by humanitarian partners directly to people in need," he added.

Humanitarian aid has also been delivered through land-crossing distribution via 70 trucks that crossed the border into Gaza, according to Dieckhaus.

Vice Admiral Brad Cooper, deputy commander of CENTCOM, noted that, "In the last several days, we've delivered over a million pounds of aid into the hands of Palestinians," adding, "We can all feel good about that."

President Joe Biden refused to say whether the U.S. has any evidence that would support the International Criminal Court prosecutor’s allegation that Israeli leaders are using starvation as a method of war in Gaza.

Biden was asked if that evidence exists and if the administration would commit to releasing that information before any warrants are issued, but he only reiterated that the U.S. does not recognize their jurisdiction.

"We've made our position clear on the ICC. We don't recognize their jurisdiction -- the ICC, the way it's being exercised -- and it's that simple. We don't think there's an equivalence between what Israel did, and what Hamas did," Biden said.

The Egyptian government said Wednesday that attempts to undermine its efforts to broker a Gaza cease-fire deal could push it to entirely pull out of mediation in the conflict.

Diaa Rashwan, the head of Egypt’s State Information Services, said Egypt categorically rejected a report from CNN that claimed his government changed the terms of a Gaza cease-fire deal that Israel had already signed off on before submitting it to Hamas.

Rashwan called the report "false" and "devoid of any information or facts."

"The ongoing attempts to cast doubt and insult the Egyptian mediation efforts and roles, with allegations that contradict reality, will only lead to further complicating the situation in Gaza and the entire region, and may push the Egyptian side to take a decision to withdraw completely from the mediation it is carrying out in the current conflict," he said in a statement.

Rashwan added that Egypt would only open the Rafah border crossing if the Palestinian side is operated by Palestinians, reiterating that Cairo does not acknowledge the Israeli control of the Palestinian side of the crossing.

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.
