Israeli Prime Minister Benjamin Netanyahu in a statement Tuesday criticized the U.S. for withholding certain weapons.

Netanyahu said when he met with Secretary of State Antony Blinken in Israel recently, he told Blinken, "It's inconceivable that in the past few months, the administration has been withholding weapons and ammunitions to Israel."

"Israel, America's closest ally, fighting for its life, fighting against Iran and our other common enemies," Netanyahu said. "Secretary Blinken assured me that the administration is working day and night to remove these bottlenecks. I certainly hope that's the case. It should be the case."

Netanyahu then quoted former U.K. Prime Minister Winston Churchill.

"During World War II, Churchill told the United States, 'Give us the tools, we'll do the job,'" Netanyahu said. "And I say, give us the tools and we'll finish the job a lot faster."

At a news conference Tuesday, Blinken declined to relate exactly what was said in private diplomatic conversations and did not deny that he had assured Netanyahu that the U.S. was working to remove bottlenecks inhibiting the supply of American arms and ammunition to Israel.

Blinken did repeatedly underscore the Biden administration’s commitment to Israel’s defense.

"It's very important to remember that our security relationship with Israel goes well beyond Gaza. Israel is facing a multiplicity of threats and challenges including in the north, from Hezbollah, from Iran, from the Houthis in the Red Sea, from various groups that are aligned against Israel and in many cases beholden to Iran," Blinken said.

President Joe Biden "will do everything he can to make sure that Israel has what it needs to effectively defend itself against these threats," Blinken said. "And a big part of that, as well, is making sure that in providing that assistance to Israel, it has a strong deterrent, which is the best way to avoid more conflict, to avoid more war, to avoid what we're already seeing in Gaza spreading to other areas."

White House press secretary Karine Jean-Pierre said the administration is surprised by Netanyahu’s claim of the U.S. withholding weapons.

“We generally do not know what he's talking about," she said Tuesday.

The Israeli military is "weeks" away from wrapping up the main part of its controversial ground invasion in and around Rafah in southern Gaza, Israel Defense Forces spokesperson Rear Adm. Daniel Hagari told ABC News.

"We are there to dismantle the military framework of the [Hamas'] Rafah Brigade," Hagari said on Monday.

"We are weeks now just from achieving this goal," he said.

The Israeli military now controls over 60% of the Rafah area, Israeli defense officials told ABC News on Monday.

The Israel Defense Forces said Monday that its soldiers have killed Muhammad Mustafa Ayoub, describing him as a "key operative" in Hezbollah’s rocket and missile department in southern Lebanon.

Hezbollah confirmed Ayoub’s death in a brief statement.

Prime Minister Benjamin Netanyahu has disbanded his war cabinet, the small group of government officials who had been tasked with overseeing decisions about the war against Hamas, a spokesperson said.

The prime minister said there was "no more need for an extra branch of government," the spokesperson said.

A meeting between U.S. and Israeli officials set for Thursday to discuss Iran has been canceled in the wake of Israeli Prime Minister Benjamin Netanyahu’s statement on Tuesday that criticized the U.S. for withholding certain weapons, according to an Israeli source familiar with the discussions.

Israeli officials Tzachi Hanegbi and Ron Dermer were both en route to the U.S. when the strategic meeting was canceled, according to a source in the prime minister's office.

A specific time had not been finalized for the meeting at the time of the cancellation, two U.S. officials told ABC News.

One official said national security adviser Jake Sullivan had been traveling and was looking to reschedule. The U.S. is working with Israeli counterparts to find a different time for the meeting.

Netanyahu said when he met with Secretary of State Antony Blinken in Israel recently, he told Blinken, "It's inconceivable that in the past few months, the administration has been withholding weapons and ammunitions to Israel."

"Israel, America's closest ally, fighting for its life, fighting against Iran and our other common enemies," Netanyahu said. "Secretary Blinken assured me that the administration is working day and night to remove these bottlenecks. I certainly hope that's the case. It should be the case."

U.S. Ambassador to Israel Jack Lew told Netanyahu Tuesday that the ammunition and weapons that he referred to are in the process of being delivered to Israel, according to the prime minister's office.

"With the exception of ongoing discussion regarding large diameter munitions, other items are either delivered or in the process of being delivered, or in the normal review process," the embassy said.

Two U.S. officials involved in approving arms transfers to Israel told ABC News Tuesday that shipments continue to be greenlit as the administration executes on both longstanding orders in the pipeline as well as new requests made after the onset of the war.

The sole exception, the officials said, is the frozen shipment of the 2,000-pound bombs. The officials said the decision to pause that delivery was made by the White House and that, if it’s ultimately lifted, they expect that order will come from the White House, too.
