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."

White House National Security Council spokesman John Kirby told ABC's "Good Morning America" Sunday that any response to Iran's Saturday night attack is up to Israeli forces.

But Kirby stressed that President Joe Biden does not want the situation to escalate or have the U.S. drawn further into any conflict.

When asked by ABC News' Whit Johnson about a response from Israel, Kirby said that it is up to the Israeli government to decide how to respond. He added that "the damage was extremely light," and the defenses in place proved Israel can defend itself.

"I won't speak for the Israelis. It's going to be up to them to decide whether and how they'll respond to this," Kirby said. "They showed last night, an incredible military capability on their own, but certainly in concert with friends."

When pressed about reports that Biden told Israeli Prime Minister Benjamin Netanyahu the U.S. would oppose a counterattack on Iran, Kirby said it was "not an accurate reading" of the president's message. He emphasized that the White House does not "want to see the situation escalate further."

"The president understands the prime minister runs a government for a sovereign state of Israel, and that they'll decide whether and how they're going to respond to what Iran did last night," Kirby said.

Kirby reiterated the White House's message that the president will do "whatever he has to protect our troops and our facilities, our people in the region." He said there is no current threat to U.S. service members and facilities, noting that more U.S. forces moved into the region after Oct. 7 to help defend Israel and shipping channels in the Red Sea.

"We're going to obviously be vigilant to any potential threat to our forces in the region," Kirby said. "But the president has been clear we are not looking for a wider war. We're not looking for a second front or a third front. We're not looking to see escalation and we're certainly not looking for a war with Iran."

Kirby added that good intelligence about the attack helped the U.S. and Israel prepare.

"We've been watching as closely as we could the intelligence picture, we had a pretty good indication of the size and the scale and the scope of what Iran was planning," Kirby said. "That is why, because we had a good sense of what they were going to do and with how much, we were able to really help Israel knock down almost everything that Iran threw at them."
