Israel-Gaza updates: Hamas military chief target of strike that killed 90 people

The survivors of Hamas' Oct. 7 massacre at Kibbutz Be’eri heard for the first time Thursday the results of an Israel Defense Forces investigation into the failed response to the attack. Over 100 people were killed at Kibbutz Be’eri and many were taken hostage.

The kibbutz members said in a statement that while the IDF's probe was "thorough," they still don’t have "satisfactory" answers to "some critical questions."

They said their questions include: "Why did not the many military forces who gathered at the gate enter the kibbutz for many hours, when the kibbutz was burning and its residents were crying for help? What caused the intelligence failure that enabled the Hamas invasion plan, and how was the border fence breached without an immediate response from the IDF?"

The kibbutz members said, "most importantly," they demand the return of the hostages.

The Biden administration lifted the suspension on 500-pound bombs for Israel that had been in place since May, when the administration placed a hold on at total of 3,500 U.S.-made bombs that it feared might be used in Rafah.

The administration announced at the time that 1,800 2,000-pound bombs and 1,700 500-pound bombs would not be delivered because of their potential use in civilian areas.

The hold on the 2,000-pound bombs will continue, a U.S. official told ABC News on Wednesday.

The official said the use of the larger bombs was the main concern because they're sometimes "co-mingled" with other munitions.

"Because our concern was not about the 500-[pound] bombs, those are moving forward as part of the usual process," the official said.

As attacks intensify along Israel's northern border with Lebanon between Hezbollah and Israel, Hezbollah leader Hassan Nasrallah said Wednesday that if a cease-fire agreement is reached, "our front will cease fire without discussion."

An Israeli delegation is headed to Doha, Qatar, to continue cease-fire talks, an Israeli official told ABC News.

Israeli Prime Minister Benjamin Netanyahu met with U.S. Presidential Special Envoy for the Middle East Brett McGurk on Wednesday, according to the Israeli prime minister's office.

In the meeting, Netanyahu "emphasized his commitment to the deal as long as Israel's red lines are preserved," Netanyahu's office said.
