Israeli Minister of Defense Yoav Gallant publicly called on Prime Minister Benjamin Netanyahu to make the "tough" decision to declare what a non-Hamas government over the Gaza Strip will look like.

"I must reiterate, I will not agree to the establishment of Israeli military rule in Gaza. Israel must not establish civilian rule in Gaza," Gallant said.

Failure to do that would undermine the IDF achievements in the war, Gallant warned.

"Since October, I have been raising this issue consistently in the Cabinet, and have received no response. The end of the military campaign must come together with political action," Gallant said.

"The 'day after Hamas,' will only be achieved with Palestinian entities taking control of Gaza, accompanied by international actors, establishing a governing alternative to Hamas’ rule," Gallant said.

U.S. Secretary of State Antony Blinken was asked how long the U.S. would standby while Israel continues to seal off the Rafah gate, cutting off Gaza from the world. Blinken told reporters it is an "urgent problem" that aid isn't getting into Rafah or Kerem Shalom. He also said the humanitarian situation is at risk of backsliding.

However, there’s no plan for the future, Blinken said.

Israel "cannot and says it does not want responsibility for Gaza. We cannot have Hamas controlling Gaza. We cannot have chaos and anarchy in Gaza. So there needs to be a clear, concrete plan. And we look to Israel to come forward with its ideas," Blinken said.

The Biden administration notified Congress on Tuesday that it is moving forward with more than $1 billion in new weapons deals for Israel, according to sources familiar with the matter at the White House and on Capitol Hill.

National Security Advisor Jake Sullivan told reporters Monday that the United States is continuing to send military assistance to Israel. The only shipment paused involves the 2,000-pound bombs, for fear they'd be used in a major invasion in Rafah, according to a U.S. official.

About 450,000 Palestinians have been displaced from Rafah, fleeing to safety, according to the U.N. Relief and Works Agency for Palestine Refugees in the Near East.

"Inland in Rafah is now a ghost town. It’s hard to believe there were over one million people sheltering here just a week ago,” UNRWA spokesperson Louise Wateridge said. "People face constant exhaustion, hunger and fear. Nowhere is safe. An immediate ceasefire is the only hope."

The development comes as airstrikes continued to hit northern and southern Gaza Tuesday. The Israeli military said it had hit 120 targets in the last 24 hours.

National security adviser Jake Sullivan stressed the U.S. is working "urgently and relentlessly" to get a hostage deal in place, but did not have any major progress to share Monday.

Sullivan noted that he met with the families of American hostages this past Friday, and that "they know how hard the president is working on this."

On where the hostage negotiations stand currently, Sullivan turned to the architect of the Good Friday agreement in Ireland.

"Sen. [George] Mitchell said quite famously, "'Negotiations are 1,000 days of failure and one day of success.' And right now, we're in the former days rather than the latter day," he said.

"[T]here could be a cease-fire tomorrow if Hamas simply released women, wounded and elderly hostages, all innocents. Israel put a forward-leaning proposal on the table for a cease-fire and hostage deal. The world should be calling on Hamas to come back to the table and accept a deal," Sullivan said.
