Israeli Prime Minister Benjamin Netanyahu is criticizing members of his coalition in a new statement. There have been reports of increased infighting since the war cabinet's dissolution on Monday.

"We are fighting on several fronts and face great challenges and difficult decisions. Therefore, I demand that all coalition partners get a hold of themselves and rise to the importance of the hour," Netanyahu said.

"This is not the time for petty politics or for legislation that endangers the coalition, which is fighting for victory over our enemies," he said. "We must all focus solely on the tasks at hand: Defeating Hamas, returning all of our hostages and returning our residents securely to their homes, both in the north and the south."

Pentagon press secretary Maj. Gen. Pat Ryder said Tuesday that the U.S. continues to withhold a single shipment of heavy bombs to Israel and that a final decision on that shipment hasn’t been made.

Ryder declined to address Israeli Prime Minister Benjamin Netanyahu’s accusation that the U.S. is slowing weapon shipments to Israel in general.

"We are absolutely committed to Israel’s inherent right to defend itself," Ryder said. "Since Hamas’ vicious attack on Oct. 7, we’ve rushed billions of dollars in security assistance to Israel to enable them to defend themselves. And we are going to continue to provide them the security assistance they need for defense."

Two U.S. officials involved in approving arms transfers to Israel told ABC News 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.

While the process of actually delivering approved transfers happens across a wide network, including the Department of Defense and private companies, the officials said they weren’t aware of any other holdups that might be perceived as a bottleneck.

In the first weeks and months of the conflict, the Biden administration worked to speed up deliveries to Israel. On two occasions in December, Secretary Antony Blinken invoked an emergency authority to expedite arms sales to Israel, bypassing congressional approval.

The Israel Defense Forces said on Tuesday that "operational plans for an offensive in Lebanon were approved and validated, and decisions were taken on the continuation of increasing the readiness of troops in the field."

White House officials are worried about a second war front opening between Israel and Lebanon at Israel’s northern border, dispatching a top aide to President Joe Biden to the region.

Amos Hochstein, a special envoy and deputy assistant at the White House, met Tuesday with Nabih Berri, the speaker of the Lebanese parliament.

"It's in everyone's interest to resolve it quickly and diplomatically. That is both achievable and it is urgent," Hochstein said, according to a transcript provided by the White House.

When asked if the two countries are on the brink of war, Hochstein said he believes a diplomatic solution is possible, adding, "But this is a very serious situation that we are in."

This meeting followed Hochstein’s in-person meetings with Israeli Prime Minister Benjamin Netanyahu and other Israeli officials on Monday.

White House national security spokesman John Kirby confirmed on Monday that the administration was concerned about the war in Gaza widening to Lebanon.

"If we weren't concerned about the possibility of escalation and a full blown, second front there, to the north, we wouldn't still be involved in such intense diplomacy that Mr. Hochstein is over there right now," Kirby told reporters in a press call.

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.

President Joe Biden issued a statement Sunday commemorating the Muslim holy day of Eid al-Adha in which he acknowledged the pain and suffering of innocent civilians in Gaza.

"In Gaza, innocent civilians are suffering the horrors of the war between Hamas and Israel.," Biden said. "Too many innocent people have been killed, including thousands of children. Families have fled their homes and seen their communities destroyed. Their pain is immense."

Biden added that his administration is working to end the war and make progress toward a two-state solution.

"And I strongly believe that the three-phase ceasefire proposal Israel has made to Hamas and that the U.N. Security Council has endorsed is the best way to end the violence in Gaza and ultimately end the war," Biden said.

Biden also cited the conflict in Sudan as well as the targeting of Muslim communities in Burma and China.

He used the holiday to celebrate the contributions of the Muslim community in America and also to say that he is committed to fighting Islamophobia in the United States.

"Hate has no place in America, whether it is targeted at American Muslims, Arab Americans including Palestinians, or anyone else," Biden said.

He added, "In the spirit of Eid al-Adha, let us all renew our commitment to values that unite us -- compassion, empathy, and mutual respect -- which are both American and Islamic."
