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.

"There is a large and clear majority in the government, the Knesset and the public in favor of a deal," Lapid said.

The U.S. continues to push Hamas to agree to the cease-fire proposal President Joe Biden outlined Friday, saying Hamas' stated opposition to the deal has yet to be officially transmitted.

"We've seen some public comments from Hamas officials, but we have not yet gotten an official response from Hamas to the Qataris, who are the mediator to whom Israel gave their proposal that was transmitted to Hamas," White House national security adviser Jake Sullivan told ABC's George Stephanopoulos on "Good Morning America" Wednesday.

"The ball is in Hamas's court," Sullivan continued. "Israel has accepted the proposal. The world has endorsed the proposal. Now it's time for Hamas to say yes to it."

Sullivan argued the latest multi-phase proposal is key to ending the war, returning hostages, and increasing the flow of aid into Gaza, while ensuring Israel's security and a better future for Palestinians.

"That's what's on offer," Sullivan said. "That's what Hamas needs to step up and take and we're awaiting to get their official response."

Asked whether Biden thinks Israeli Prime Minister Benjamin Netanyahu was prolonging the war for political gain — which he suggested in a Time magazine interview out Tuesday — Sullivan pointed to Biden's answer to a question Tuesday evening asking if Netanyahu was playing politics.

"I don't think so. He's trying to work out the serious problem he has," Biden said Tuesday.

"And from our perspective, we're not going to delve into Israeli politics," Sullivan added. "What we're going to do is focus on the fundamental task at hand, which is President Biden's effort to end this war, get the hostages home, make sure Israel's safe and make sure the Palestinian people have a decent future."
