Security officials from Egypt, the United States and Qatar will meet in Doha on Wednesday to look at ways to revive the Gaza truce negotiations, a senior Egyptian official told Egyptian state media.

Hamas rejected the Israeli cease-fire plan endorsed by President Joe Biden on Tuesday, saying they won't agree to anything until Israel commits to halting all military operations in Gaza.

World Central Kitchen has now served 50 million meals in Gaza, the organization announced during a press briefing Tuesday.

"I'd like to announce that we have just crossed the 50 million meal mark in Gaza. That is a huge accomplishment for us. We're about 50,100,000 right now. As many of you know, we had to pause our work in Gaza after the Israeli attack on our personnel convoy on April 1, which killed seven of our colleagues," World Central Kitchen Chief Communications Officer Linda Roth said during the press conference.

"Jose, our founder, says the decision to restart feeding in Gaza was both the hardest and the simplest one we could make," Roth said.

Right now, the organization has two main World Central Kitchen kitchens operating in Gaza in Deir al Balah and Mawasi, and "another 65 community kitchens spread throughout the strip," Roth said.

"We have about 400 Palestinian Response Corps members and hundreds and hundreds of more volunteers that are working to feed everyone in Gaza. It's Palestinians feeding Palestinians," Roth said.

The Israel Defense Forces say things have reached a breaking point along its border with Lebanon, where there has been an exchange of attacks between Israel and Hezbollah for months.

"We are approaching the point where a decision will have to be made, and the IDF is prepared and very ready for this decision. We have been striking here for eight months and Hezbollah is paying a very, very high price," Herzi Halevi, a spokesperson for the IDF, said Tuesday.

"Hezbollah has increased its attacks in recent days and we are prepared after a very good process of training up to the level of a General Staff exercise to move to an offensive in the north. Strong defense, readiness for an offensive, we are approaching a decision point," the IDF said.

The current cease-fire proposal has majority support in the Knesset, Israeli parliament, according to Israeli opposition leader Yair Lapid.

A weapon used in a strike on a UNRWA school sheltering displaced people on June 6 appears to be U.S.-made, three munitions experts told ABC News.

Journalist Emad Abu Shawiesh captured video of weapons fragments at the UNRWA al Sardi school building in Nuseirat in Gaza on June 6.

The weapon fragments seen in the video are consistent with the nose section of a U.S.-made GBU-39 "Small Diameter Bomb," Trevor Ball, a former U.S. Army explosive ordinance disposal specialist, told ABC News.

The GBU-39 also appeared to have been employed in a deadly strike on May 26 in Rafah, Gaza, according to Ball and another munitions expert, who asked not to be named due to the sensitivity of the issue.

Mark Hiznay, an associate director with the Crisis, Conflict and Arms Division of Human Rights Watch, told ABC News the image shows the remnants of a GBU-39.

N.R. Jenzen-Jones, a director at the consultancy Armament Research Services, said the image was consistent with the Small Diameter Bomb series.

“Given what we know about the IDF arsenal and munitions used in previous strikes, the remnants are most likely from a GBU-39 SDB and include a portion of the nose (forward section) of the bomb,” Jenzen-Jones said, adding that other munitions could have been used in the strike, which he had not yet assessed in detail.
