The U.S. has assessed that Israel has amassed enough troops on the edge of Rafah to move forward with a full-scale incursion into the city, but the U.S. is not sure if Israel has made a final decision to actually do so, according to two U.S. officials.

One official added that the U.S. does not have a timeline or estimate on when Israel could potentially move forward with operations.

The official stressed the U.S. continues to have the same concerns for civilian safety in Rafah.

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.

Three U.S. medical professionals remain in Gaza despite warnings from the U.S. State Department that the American government may not be able to get them out later.

Tamer Hassan, a registered nurse, Dr. Jomana Al-Hinti and Dr. Adam Hamawy were the only ones out of a group of 20 American medical professionals who stayed behind to help treat patients.

"They understand that the U.S. embassy may not be able to facilitate their departure in the same manner as we have just effected today," a person with knowledge of the situation told ABC News.

Hamawy released a statement Saturday explaining why he stayed behind.

"We worry that the European Hospital we currently are in will suffer a similar fate of Al-Shifa and Nasser hospitals, where humanitarian workers, patients, and civilians were massacred," he said.

"To my wife, daughters and son, I know it hurts that I am not coming home this weekend, and I am sorry. But I know that you are proud that I am upholding my oath to never leave anyone behind," he added.

The doctors who left Gaza "made their way to safety with assistance from the U.S. Embassy in Jerusalem," a State Department spokesman said.
