Britain's Defense Minister Grant Shapps said early Sunday morning local time that the U.K. is deploying "additional Royal Air Force" aircraft following Iran's attack on Israel.

"I have authorised the deployment of additional Royal Air Force assets. The RAF jets and air refuelling tankers will bolster our existing Operation Shader – the UK’s existing counter-Daesh operation in Iraq and Syria," Shapps' statement read. "In addition, these jets will intercept any airborne attacks within range of our existing missions, as required."

Following the news of the RAF deployment, U.K. Prime Minister Rishi Sunak said in a statement he "condemns in the strongest terms" Iran's attack on Israel.

"Iran has once again demonstrated that it is intent on sowing chaos in its own backyard," his statement read. "The UK will continue to stand up for Israel’s security and that all of our regional partners, including Jordan and Iraq.

"Alongside our allies, we are urgently working to stabilize the situation and prevent further escalation. No one wants to see more bloodshed."

Israel's national emergency services -- the Magen David Adom -- said it has received no reports of casualties after air raid sirens activated all over Israel.

The MDA has received calls of "stress symptoms" and injuries that occurred while people were "running to the protected areas."

With Iranian missiles still heading to Israel, the IDF has told the public to stay alert.

When an alarm sounds, people "must enter shelter and wait there for no less than ten minutes," the IDF said early Sunday morning local time.

Israel's air defense continues to intercept threats, and Israel's Air Force has planes in the air "ready to counter any threat."

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."
