Israel-Gaza updates: Israel says ground operation underway in southern Gaza

Israel plans to put in place "security arrangements" along the fringes of the Gaza strip to ensure that Hamas could not threaten the country again, Mark Regev, Prime Minister Benjamin Netanyahu's adviser, told reporters Saturday.

"Call it what you want," Regev told ABC News in an interview after the briefing. "Israel will have to have a security envelope."

Regev told reporters that Israel does not plan to take territory from Gaza or occupy the strip, but he spoke about establishing "security zones."

"There will have to be security arrangements on the ground to prevent future attacks," Regev told the briefing.

After reaching an "impasse" in negotiations with Hamas, Prime Minister Benjamin Netanyahu ordered Israel's negotiation team to return from Doha, Qatar, Israeli officials said.

"The terrorist organization Hamas did not fulfil its part of the agreement, which included the release of all children and women according to a list that was forwarded to Hamas and approved by it. The head of the Mossad thanks the head of the CIA, the Egyptian Minister of Intelligence and the Prime Minister of Qatar for their partnership in the tremendous mediation efforts that led to the release of 84 children and women from the Gaza Strip in addition to 24 foreign citizens," according to a statement issued on behalf of Israel's Intelligence and Special Tasks Agency.

Following the end of the temporary cease-fire, humanitarian aid stopped flowing into Gaza through the Rafah crossing between Egypt and the Gaza Strip, National Security Council spokesman John Kirby confirmed Friday.

But Kirby added, "I just saw some reporting that looks like a spokesman for the Israelis have now said that the trucks were going to be allowed into Gaza at our [U.S.] request, and certainly with the approval of their government."

"They [Israel] stressed that all the trucks going in, of course, had to be done with this inspection regime in Israel before entering Gaza," he said. "That looks like a good sign going forward."

The Palestine Red Crescent Society said earlier Friday that Israel was not letting aid pass through Rafah to Gaza.

"Israeli occupation forces informed all organizations and entities operating at the Rafah border crossing that the entry of aid trucks from the Egyptian side to the Gaza Strip is prohibited, starting from today until further notice," the Palestine Red Crescent Society said.

Pressed about The New York Times report alleging Israel knew about Hamas' attack plan a year in advance, National Security Council spokesman John Kirby told ABC News that the U.S. "can't verify the reporting."

Kirby did not provide any details when asked if President Joe Biden had seen the report, if the Biden administration has or will raise the document with the Israelis or if this report strains trust with the Israelis.

"I’m just not gonna go into more details than what I did before,” Kirby said. "We can’t verify the reporting … and I’m just going to leave it at that."

A U.S. official said "there are no indicators at this time that the [U.S.] Intelligence Community was provided" the document referenced in The New York Times report.

When asked about a possible timeline to resume the pause in fighting, Kirby said, "We are working at this literally by the hour to try to see if we can get [the temporary cease-fire] restored."

"We have every expectation that another pause could be executed," he said.
