Strikes in multiple neighborhoods across northern Gaza today have killed 42 people according to Gaza's Civil Defense. Videos from the immediate aftermath of the strike show an entire building leveled, children covered in dust.

A bombing of Al-Shati camp killed 24 people, a bombing in Al-Tufaah killed 18 people -- the number of casualties is likely to increase -- and a bombing in Al-Zaytoun killed 7 people, according to Civil Defense.

Fifty others were injured in the attacks, according to the Hamas media office.

Several others are still trapped under the rubble.

The Israel Defense Forces told ABC News they struck two Hamas military infrastructure sites in Gaza City.

Israeli Prime Minister Benjamin Netanyahu told Punchbowl News that he felt his video publicly accusing the Biden administration of withholding weapons "was absolutely necessary after months of quiet conversation that did not solve the problem."

"We began to see that we had some significant problems emerging a few months ago. And, in fact, we tried, in many, many quiet conversations between our officials and American officials, and between me and the president, to try to iron out this diminution of supply. And we haven’t been able to solve it," Netanyahu said.

"I raised this issue with Secretary [of State Antony] Blinken. And I said that we are being told by our Defense Department officials that barely a trickle is coming in. He said, ‘Well, everything is in process. We’re doing everything to untangle it. And to clear up the bottlenecks,'" Netanyahu continued.

The U.S. has pushed back on Netanyahu's claim, noting that only one shipment of 2,000-pound bombs has been withheld.

White House national security spokesman John Kirby said Thursday that Netanyahu's video "was vexing and disappointing to us -- as much as it was incorrect."

"No other country is doing more to help Israel defend itself," Kirby said.

Netanyahu said in his July 24 remarks to Congress, he plans "to speak to the broad spectrum of the American people and to cull bipartisan support that is still solid in America."

The flow of aid through a temporary pier off the coast of Gaza has resumed after it was preemptively detached from the beach to ride out rough seas, the Pentagon confirmed.

"I can confirm that U.S. Central Command personnel re-anchored and re-established the temporary pier to the Gaza beach yesterday," Pentagon spokesperson Maj. Gen. Pat Ryder told reporters Thursday. "As has been the case in the past, Israeli Defense Force engineers provided all the necessary support to ensure the safe and placement of the pier on the beach. And there were no U.S. boots on the ground during the reestablishment of the pier."

Since resuming overnight, more than 1.4. million pounds of humanitarian assistance has flowed from Cyprus to Gaza, he said.

Overall, more than 9.1 million pounds have been delivered through the corridor since May 17, he said.

Ryder stressed that no end-date has been established for the pier mission.

"We'll continue to facilitate the transfer of humanitarian aid via the maritime corridor and as always take necessary steps to ensure the safety and security of the personnel operating the pier to include adjusting to sea states in the eastern Mediterranean Sea," he said.

White House national security spokesman John Kirby said the video released by Israeli Prime Minister Benjamin Netanyahu claiming the U.S. had paused weapons shipments was a surprise.

The video was "perplexing to say the least" and "certainly disappointing, especially given that no other country is doing more to help Israel defend itself," Kirby told reporters on Thursday.

Netanyahu said in a video Tuesday, "It's inconceivable that in the past few months, the administration has been withholding weapons and ammunitions to Israel."

Asked if the administration had any sense of why Netanyahu felt it was necessary to release the video, Kirby reiterated their frustration.

"No idea. You'd have to talk to the prime minister about what prompted him to do that. Again, it was vexing and disappointing to us -- as much as it was incorrect. So difficult to know exactly what was on his mind," he said.

Kirby was also asked about efforts behind the scenes to get an apology from Netanyahu over the video. Kirby said, "I think we've made it abundantly clear to our Israeli counterparts from various vehicles our deep disappointment in the statements expressed in that video and our concerns over the accuracy in the statements made."

Netanyahu said in response Thursday, "I am ready to suffer personal attacks provided that Israel receives from the U.S. the ammunition it needs in the war for its existence."

Kirby also confirmed that national security adviser Jake Sullivan was still holding a meeting on Thursday with high-level Israeli officials.

Kirby said the "wide-ranging meeting" will include "everything that's going on with the Gaza war, with our support to Israel, with our efforts to get a better sense of how they're continuing to prosecute operations against Hamas, as well as continuing to talk about the importance of closing on this deal."

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.
