After meeting with U.K. Foreign Secretary David Cameron and German Foreign Minister Annalena Baerbock on Wednesday, Israeli Prime Minister Benjamin Netanyahu said he appreciates their advice, but added, "We will make our own decisions and the State of Israel will do everything necessary to defend itself."

Cameron told reporters after the meeting in Jerusalem, "It's clear the Israelis are making a decision to act."

"We hope they do so in a way that does as little to escalate this as possible, and in a way that -- as I said yesterday -- is smart as well as tough," Cameron added.

Cameron also reiterated that the "real need is to refocus back on Hamas, back on the hostages, back on getting the aid in, back on getting a pause in the conflict in Gaza."

"That's why I'm here today to talk to the Israeli government, to talk to the Palestinian Authority to try and push those things forward," Cameron said.

The United States announced Tuesday it will impose new sanctions targeting Iran in the coming days following its "unprecedented air attack against Israel."

The sanctions include targeting Iran's missile and drone program and new sanctions against entities supporting the Islamic Revolutionary Guard Corps and Iran’s Defense Ministry, according to the White House's national security adviser, Jake Sullivan.

"We anticipate that our allies and partners will soon be following with their own sanctions,” Sullivan said in a statement. "We will not hesitate to continue to take action, in coordination with allies and partners around the world, and with Congress, to hold the Iranian government accountable for its malicious and destabilizing actions."

The U.S. is telegraphing its sanction plan in advance to underscore the large international response that the U.S. is coordinating and to signal to Iran there will be diplomatic costs to what they've done, a senior administration official told ABC News. The official said they believe this will have an impact, in part, by bringing other countries on board.

Six months into the Israel-Hamas conflict, the conduct and ethics of some Israel Defense Forces members have increasingly come under the microscope.

Incidents ranging from pranks to potentially criminal acts are being exposed to the world, often by videos soldiers themselves have posted online, according to critics and Israeli officials.

In many pictures and videos that have circulated since the conflict began, and which were reposted by pro-Palestinian activists to millions of followers, IDF soldiers are seen blowing up buildings in Gaza while in combat, waving women’s underwear like flags and rifling through the possessions of Gazans with gleeful expressions.

Younis Tirawi, a Palestinian activist, says he’s seen thousands of videos of IDF soldiers reportedly behaving improperly.

"You can see all the soldiers liking their posts," Tirawi told ABC News.

Secretary of State Antony Blinken spoke with Israeli war cabinet minister Benny Gantz, during which Blinken "continue[d] to send the same messages in all his conversations -- which is we do not want to see further escalation of the conflict," according to spokesperson Matt Miller.

Miller declined to say whether the U.S. assessed the threat of escalation had fallen, but an administration official said the amount of time that has already elapsed since Iran’s weekend attack had boosted hopes that Israel would exercise constraint.

Miller batted down reports that Iran and the U.S. were communicating through intermediaries in the wake of Tehran’s attack on Israel.

"There have not been such messages delivered. It's been days since we've communicated -- since we've sent messages to the government of Iran," Miller said. "And I say that as a reminder of something we've said before: Oftentimes, the Iranian government has misled the world about either messages they've passed to us or messages that we have passed to them."

Israel on Saturday demonstrated its "military superiority" against Iran while also showcasing its partnership with military allies, including the United States, John Kirby, spokesperson for the White House National Security Council, said Monday.

Israel said Sunday about 99% of the missiles and drones launched by Iran were intercepted by Israel and its allies, a defense that Kirby called a "tremendous success."

"I think it did show, did demonstrate that Iran is not the power that it purports to be, that it doesn't have that same military superiority," Kirby said on "Good Morning America."

Israeli Prime Minister Benjamin Netanyahu is expected on Monday to reconvene his war cabinet, a body that met on Sunday without deciding on a response to Iran's attack. And President Joe Biden and his G7 counterparts on Sunday released a statement urging Iran to cease its attacks.

"With its actions, Iran has further stepped toward the destabilization of the region and risks provoking an uncontrollable regional escalation," the G7 leaders' statement said. "This must be avoided."

The United States would not participate in an Israeli response, if the country decides to strike back against Iran, U.S. defense and security officials said on Sunday.

But the final decision on whether Israel strikes back will fall to Netanyahu, Kirby said Monday.

"The president was also clear, as he has been throughout, that we do not seek a wider war in the region and we don't seek conflict with Iran," he said.
