Israel-Gaza updates: 22, including 18 children, reported dead in Rafah strikes
The IDF says it struck military targets of terrorist organizations in Gaza.
Israel launched a retaliatory strike against Iran early Friday morning local time, a senior U.S. official told ABC News.
The strike followed Iran's attack on Saturday, when Tehran sent a volley of more than 300 drones and missiles toward targets in Israel, according to Israeli military officials. All but a few were intercepted by Israel and its allies, including the United States, officials said.
Iran's weekend attack came more than six months after Hamas terrorists invaded Israel on Oct. 7, after which the Israeli military began its bombardment of Gaza.

What to know about Iran's attack on Israel
Israeli officials said the country's Iron Dome defense system endured a big test from Iran's attack on Saturday, intercepting 99% of the 300 "threats of various types" thrown at it.
Iran's Islamic Revolutionary Guard Corps, according to Israel Defense Forces spokesperson Daniel Hagari, launched 170 unmanned aerial vehicles (UAVs), more than 120 ballistic missiles and more than 30 cruise missiles in the attack.
Hagari said "99% of the threats launched towards Israeli territory were intercepted -- a very significant strategic achievement."
Hagari said the attack resulted in only one known Israeli casualty, a 7-year-old girl who was severely injured when she was struck by shrapnel apparently from an intercepted missile.
Iran did not give US heads up on Israel attack: Pentagon
Maj. Gen. Pat Ryder, the Pentagon press secretary, said Monday that Iran did not give the U.S. an advanced notice of its attack on Israel.
"I think what you're asking was did Iran give us a heads up? No, they did not," Ryder said, without indicating whether the U.S. learned of Iran's plans through allies.
Ryder said U.S. forces in the Middle East intercepted dozens of missiles and unmanned aerial vehicles when Iran and its proxies launched attacks in retaliation for Israel's strike earlier this month on the Iranian Consulate in Damascus, Syria, that killed an Iranian military leader.
Ryder repeated assessments that 99% of incoming Iranian fire was intercepted by Israel and its partners, but he wouldn't confirm reports that half of the launches failed to get off the ground.
Secretary of Defense Lloyd Austin, Ryder said, has spoken with Israeli Defense Minister Yoav Gallant three times since the attack.
"During their most recent call yesterday, the two leaders reviewed the successful combined operation by the United States, Israel and their partners to defend Israel from these unprecedented attacks by Iran and its proxies and emphasize that while the United States does not seek escalation, we will continue to take all necessary action to defend Israel and U.S. personnel," Ryder said.
Asked whether the response to Iran's attack depleted the air defense resources of Israel and its partners, Ryder declined to answer.
"As we demonstrated this weekend, we have the capability and the capacity to defend Israel and to defend our forces in the region," he said.

US to Israel: If you strike back at Iran, you'll do it alone
As Israel on Monday weighed its response to Iran’s weekend attack, the U.S. is privately telling officials there: If Israel strikes back militarily, it will do so alone.
It's an unusual message for a close ally that's spent decades receiving more U.S. military aid than any other country in the world and whose relationship with America is often described as "ironclad."
But after months of Israel acting on its own in Gaza -- and facing tough criticism from the U.S. and other allies that its military operations have gone too far – the Biden administration made clear the U.S. wouldn't participate in offensive military operations against Iran, fearing a broader war in the Middle East.
"We believe Israel has freedom of action to protect itself and defend itself," a senior administration official told reporters shortly after Iran's attack ended. "That's a long-standing policy, and that remains."
When asked by a reporter if the U.S. would help Israel counter with offensive military operations, the official said no.

Biden: We 'defeated' Iran
President Joe Biden on Monday touted the "unprecedented military effort to defend Israel" against Iran, declaring "together with our partners we defeated that attack."
In his first on-camera remarks since this weekend's Iranian strike, the president stressed that "the United States is committed to Israel's security."
"We're committed to a cease-fire that will bring the hostages home and preventing the conflict from spreading beyond what it already has" the president told reporters in the Oval Office ahead of his meeting with the Iraqi prime minister. "We are also committed to the security of our personnel and our partners in the region, including Iraq."
Israeli Defense Minister responds to potential US sanctions on IDF battalion
Israel's Minister of Defense Yoav Gallant held a discussion with IDF Chief of the General Staff Lt. Gen. Herzi Halevi regarding the developing report on U.S. intentions to impose sanctions against the IDF’s Netzach Yehuda battalion, an Israeli military unit operating in the West Bank.
"Any attempt to criticize an entire unit casts a heavy shadow on the actions of the IDF, which operates to protect the citizens of Israel," Gallant said in a statement. "Damage to one battalion, affects the entire defense establishment – this is not the right path for partners and friends."
Gallant urged the U.S. not to impose sanctions on the unit.
"Our friends and our enemies are closely watching the ties between Israel and the United States, now more than ever," Gallant said. "I call on the U.S. Administration to withdraw its intention to impose sanctions on the Netzach Yehuda battalion."
Amid reports of possible sanctions, Gallant recently completed a call with U.S. Secretary of State Antony Blinken. Earlier today, Minister Gallant also held a discussion with the U.S. Ambassador to Israel, Jack Lew.
