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.

The Hamas military wing claimed in a statement Sunday that three hostages, including an American citizen, were killed in Saturday's rescue operation in central Gaza that was carried out by the Israel Defense Forces.

The IDF told ABC News on Sunday it had no knowledge of hostage deaths occurring during Saturday's raid on the Nuseirat refugee camp, in which four hostages were rescued.

In its statement, Hamas' Al-Qassam Brigades accused the Israeli government of being untruthful about the circumstances of the raid.

"In exchange for them, your own army killed three of your own captives in the same attack; one of them holds an American citizenship," the Al-Qassam Brigades statement said. "Time is running out. Your government is lying."

A White House National Security Council spokesperson said Sunday they have "seen nothing to corroborate" the claims that three other hostages, including an American, were killed during the raid.

"We have seen nothing to corroborate these claims. We are of course continuing to assess the claims," the spokesperson told ABC News.

At least 274 people were killed when the Israeli military moved into the Nuseirat camp to rescue hostages, the Hamas-run Gaza Health Ministry said Sunday. Israel's military said no more than 100 civilians were killed in the operation.
