At least nine Iranian missiles that breached Israel's air defenses struck two of Israel's air bases, but no significant damage was reported, a senior U.S. official told ABC News.

Five ballistic missiles hit the Nevatim Air Base, damaging a C-130 transport aircraft, an unused runway and empty storage facilities, the official said. Four additional ballistic missiles hit the Negev Air Base, but there were no reports of significant damage, the official said.

A spokesperson for the Israel Defense Forces said earlier Sunday that 99% of the 300 "threats of various types" Iran launched at Israel, including 120 ballistic missiles and more than 30 cruise missiles, were intercepted by Israel's air defense system and Israeli Air Force fighter jets, as well as "aerial defense systems and aircraft of our partners."

While the Biden administration remains committed to defending Israel, top administration defense and security officials made it clear Sunday the U.S. would not be a part of any Israeli response.

"We believe Israel has freedom of action to defend itself, in Syria or elsewhere. That's a long-standing policy and that remains," a senior official said. "But no, we would not envision ourselves participating in such a thing."

Defense Secretary Lloyd Austin spoke with Israeli Defense Minister Yoav Gallant Sunday afternoon, according to a U.S. official who described the exchange as “direct.” The official said Austin told Gallant that while the U.S. will continue to defend Israel, it does not envision being part of offensive operations against Iran.

A senior administration official also said President Joe Biden stressed to Prime Minister Benjamin Netanyahu in a call Saturday night that Israel had prevailed against Iran's strike against Israel.

President Joe Biden and Jordanian King Abdullah II spoke on the phone Sunday about Iran's attack on Israel, according to the White House.

The two leaders discussed Iran's "unprecedented attack" on Israel, the White House said without elaborating.

Earlier Sunday, Biden met with G7 leaders, who jointly condemned Iran's attack on Israel.

"We, the Leaders of the G7, unequivocally condemn in the strongest terms Iran’s direct and unprecedented attack against Israel. Iran fired hundreds of drones and missiles towards Israel. Israel, with the help of its partners, defeated the attack," the G7 leaders said in a joint statement.

The statement added, "We express our full solidarity and support to Israel and its people and reaffirm our commitment towards its security."

The G7 leaders said the actions of Iran "further stepped toward the destabilization of the region and wrists provoking uncontrollable regional escalation."

"We demand that Iran and its proxies cease their attacks, and we stand ready to take further measures now and in response to further destabilizing initiatives," the statement said.

Iran has launched dozens of drones toward Israel, but it could take hours for them to reach, according to Israel Defense Forces spokesperson Daniel Hagari.

Israel is closing down its airspace after midnight local time and Israel's defense systems are deployed, according to Prime Minister Benjamin Netanyahu.

"We are prepared for any scenario, both in defense and attack," Netanyahu said in a video statement.

"The IDF is on high alert and is constantly monitoring the operational situation. The IDF Aerial Defense Array is on high alert, along with IAF fighter jets and Israeli Navy vessels that are on a defense mission in Israeli airspace. The IDF is monitoring all targets," the IDF said in a statement.

"We ask the public to adhere to and follow the instructions of the Home Front Command and the official IDF announcements regarding the matter," the statement added.
