According to Israel Defense Forces Spokesperson Daniel Hagari, Hamas is no longer in control of certain parts of the Gaza Strip and the IDF is currently focused on killing Hamas leaders and their terrorist fighters

Meanwhile, fighting is ongoing going on in the south of Israel and there were four different incidents with 15 militants killed overnight, Hagari said.

The IDF has now notified another 200 families of lost IDF soldiers while engineers are working as quickly as possible to fix the Gaza border fence, according to Hagari.

United States Defense Secretary Lloyd Austin and NATO Secretary General Jens Stoltenberg warmly greeted each other before the second day of NATO sessions at its Brussels headquarters.

Austin invoked the conflict in Israel ahead of the meetings, saying "I know you share our outrage at the terrorist attack on Israel by Hamas and also our determination to support Israel's right to defend itself."

Austin and his counterparts are expected to discuss support for Ukraine, NATO's missions and operations in Kosovo and Iraq and will also be briefed on the ongoing situation in Israel by Minister of Defense Yoav Gallant, Stoltenberg said.

"On all of these issues, the Middle East, Ukraine, Iraq -- the United States, and you personally, Secretary Austin, provides security and leadership for all the NATO allies, and that is something we really, really appreciate." Stoltenberg said.

Sharing similar sentiments, Austin said that "NATO is as strong and as united as I've ever seen it."

Yuval Patiev, a young Israel Defense Forces commander, recounted to ABC’s David Muir on Wednesday night’s special edition of “20/20” what happened early Saturday morning when he was among the first to respond to the Hamas attacks.

"One terrorist climbed under the tank,” Patiev told Muir of the militants who charged at his unit. “He put an explosive bomb right under my seat.”

The bomb went off and injured the 20-year-old, who is now in a hospital.

“When it exploded, I flew in the air. At that moment, I knew that I broke my leg,” he said.

Fearing he could lose his leg, Patiev took immediate action.

“I told my commander that he should take my tourniquet and should put it on that,” he said, adding, “I just did what they trained us [to do].”

The young soldier’s unit was trapped in their tank for hours, and from his hospital bed, he recalled seeing the faces of the militants who attacked.

“You look at them, and how could you do this to someone? All I saw was hate,” Patiev said. “So we just fought for our lives … and [we were] trying to pray that they won't get to open the tank, won't explode it. And God was with us; that's all I can say."

The IDF announced Thursday morning that it has launched an "extensive attack" on "many centers" of Hamas in the Gaza Strip.

The post was shared on X.

A State Department official said Monday night that the department has offered 4,000 American citizens and their immediate family members help to depart Israel via government-organized transportation since Friday.

“Since Oct. 13, we have augmented the limited commercial flight availability by offering more than 4,000 seats on U.S. government-chartered transport by air and sea to U.S. citizens and their immediate family members,” one official said. “We have communicated the availability of departure assistance options for U.S. citizens via targeted, individualized messaging as well as via broad public messaging.”

Departing flights, though, were not nearly at capacity, the official said.

“The departure options we have offered have generally departed at half capacity or less. Nearly 1,000 U.S. citizens and their immediate family members have departed on U.S. government-chartered transport,” an official said.

The official added that 3,000 other American citizens have told the State Department that they were able to leave Israel and the West Bank on their own.
