Israel-Gaza updates: IDF says 3,500 'terror targets' hammered in 10 days

Another U.S. military aircraft landed in Egypt on Friday with 57,000 pounds of food, water and medicine to aid people in Gaza, National Security Council spokesperson John Kirby said.

"We're mindful of the extreme humanitarian suffering inside Gaza and we're doing everything we can to help alleviate that," he said.

Kirby also said the administration is "very grateful" that the Israelis agreed to open the Kerem Shalom crossing at the Israel-Gaza-Egypt border, saying it was "very much at our request" that they did so. He said it had been a point of discussion between President Joe Biden and Israeli Prime Minister Benjamin Netanyahu.

“It's good news, but we're just at the beginning of this process," he said of the Kerem Shalom crossing opening. "The first step is to set up an inspection regime, sort of akin to what's going on down in Rafah [at the Gaza-Egypt border crossing], so that the Israelis can have a measure of satisfaction that what's getting in [to Gaza] is actually what's supposed to be getting in there."

The Israel Defense Forces said it conducted a hostage rescue operation overnight in the Gaza Strip that failed to rescue any hostages.

Two IDF soldiers were severely injured in the operation while "numerous" Hamas terrorists who "took part in the abducting and holding of hostages were killed," the IDF said.

"The IDF continues to operate in a variety of operational and intelligence methods, together with security organizations, in order to release the hostages, and to collect relevant information," the IDF said.

"Civil order is breaking down in Gaza" and "society is on the brink of full-blown collapse," warned Thomas White, director of UNRWA affairs in Gaza.

"The streets feel wild, particularly after dark," White wrote Friday on X, the social media platform formerly known as Twitter.

He said some aid convoys have been looted and some U.N. vehicles were stoned.

With Gaza under "constant bombardment" and food and supplies limited, the "UNRWA’s ability to assist and protect people is reducing fast," Philippe Lazzarini, commissioner-general of the UNRWA, said in a letter to the president of the U.N. General Assembly.

“In my 35 years of work in complex emergencies, I would never have expected to write such a letter, predicting the killing of my staff and the collapse of the mandate I am expected to fulfill," Lazzarini said. "I urge all member states to take immediate actions to implement an immediate humanitarian cease-fire, enforce international law including the protection of civilians, U.N. staff, U.N. premises including shelters, medical facilities and all civilian infrastructure and protect the prospects for a political solution vital to peace and stability and the rights for Palestinians, Israelis, the region and beyond."

The Israel Defense Forces said Friday morning that it has struck approximately 450 targets in the Gaza Strip over the past day from the air, sea and ground amid "extensive battles with terrorists."

"The troops continue to operate to locate and destroy underground tunnel shafts, weapons, and additional terror infrastructure," the IDF said in a statement.

During operations in Gaza’s southern city of Khan Yunis, Israeli ground troops directed fighter jets "to kill numerous terrorists in a two-hour series of precise strikes," according to the IDF.

Overnight, Israeli warships "used precise ammunition to strike dozens of terror infrastructure sites used by the Hamas naval forces in the central and southern Gaza Strip," the IDF said.
