Israel-Gaza updates: Gantz rejects Netanyahu's request, resigns

State Department spokesperson Matthew Miller said the current cease-fire proposal is "nearly identical to what Hamas said it would accept just a few weeks ago," and said the U.S. and other mediators had not yet received an official response to the proposal from the militant group.

"The world should know, the Palestinian people should know, that the only thing standing in the way of an immediate cease-fire today is Hamas," Miller declared.

Miller said there were some gaps between the proposal Hamas said it would agree to in the past, but added that the U.S., Qatar and Egypt all felt that they could be easily reconciled.

The foreign ministers of Egypt, Qatar, Jordan, Saudi Arabia and the United Arab Emirates released a joint statement Monday in support of the current cease-fire deal.

The ministers met virtually to discuss the proposal and mediation efforts to reach a deal and hostages-for-prisoners swap, as well as the sufficient entry of aid into Gaza, the statement said.

The G7 leaders also issued a statement in support of the current deal.

President Joe Biden outlined Israel’s cease-fire proposal accurately in his Friday speech, the White House maintained Monday, pushing back on suggestions he miscommunicated the offer.

"The Israeli foreign minister himself acknowledged that this was the Israeli proposal ... and we're confident that it accurately reflects that proposal, a proposal that we worked with the Israelis on," White House national security communications adviser John Kirby told reporters.

Kirby also argued that Biden "felt it was important" to reveal details from ongoing cease-fire negotiations for the first time, saying it was meant to apply pressure on Hamas, not to corner Israeli Prime Minister Benjamin Netanyahu.

"We don't typically go through the details of these kinds of proposals," Kirby said. "But in this case, given where we are, given how much longer the hostages have now been held, given the fact that Hamas has reneged on several past occasions, on proposals that were sent to them, and given the fact that the Israelis really did work hard to come up with this proposal, and did so in good faith, the president felt it was important for the first time to publicly lay that out."

"This wasn't about jamming the prime minister or the war cabinet," Kirby added. "This was about laying bare for the public to see how well and how faithfully and how assertively the Israelis came up with a new proposal, how it shows how much they really want to get this done."

Kirby said Biden delivered the speech on Friday afternoon because the deal was presented to Hamas the night before.

"We're awaiting an official response by them now to take the deal," Kirby said. "This gives them what they've been looking for, which is a cease-fire and over time, and through the phases, the potential withdrawal of Israeli forces from Gaza."

Israeli Prime Minister Benjamin Netanyahu has released his first public statement since President Joe Biden's Friday speech endorsing the original Israeli cease-fire deal.

"We are working in countless ways to return our abductees," Netanyahu said in Hebrew on Monday. "That's why we went a long way to bring them back, but in the process of this action we maintained the goals of the war, chief among them the elimination of Hamas."

"We insist that we complete both this and that. It's part of the outline, it's not something I'm adding now, it's not something I'm adding because I was pressured in the coalition, it's something we unanimously agreed on in the war cabinet," Netanyahu added.
