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

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.

In the last 24 hours, 52 people have been killed in Gaza and another 208 people have been injured, the Hamas-run Gaza Ministry of Health said.

The Israel Defense Forces said over the last day its forces have killed terrorists in areas in southern Gaza, central Gaza and northern Gaza.

The IDF said one of the counterterrorism operations overnight targeted "terrorists who were operating inside UNRWA's Headquarters."

"After a defined corridor was opened to facilitate the evacuation of civilians from the area, IDF troops conducted a targeted raid on the structure, eliminated terrorists in close-quarters combat, and located large amounts of weapons," the IDF said.
