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.
Israel aborted strikes against Iran 2 nights this week: Sources
Israel prepared for and then aborted retaliatory strikes against Iran on at least two nights this past week, three Israeli sources told ABC News.
Iran attacked Israel with more than 300 drones and missiles on Saturday night into Sunday morning local time in Israel. Israel has been weighing how and when to respond to Iran's attack since then, holding war cabinet meetings on Sunday, Monday and Tuesday.
The members of the Israeli war cabinet are Israeli Prime Minister Benjamin Netanyahu, Minister Benny Gantz and Defense Minister Yoav Gallant.
A range of responses have been presented to the Israeli war cabinet. The potential responses include options ranging from attacking Iranian proxies in the region but not on Iranian soil to a potential cyber attack, sources told ABC News.
There was no war cabinet meeting on Wednesday, but Netanyahu told his government cabinet that while he appreciates the advice from allies, Israel will "make our own decisions, and the State of Israel will do everything necessary to defend itself."

House Republicans have posted the legislative text for three national security bills, addressing Ukraine, Israel and the Indo-Pacific.
For Israel, lawmakers have crafted a package totaling $14.1 billion, including: $4 billion for missile defense; $1.2 billion for Iron Beam; $4 billion replenishment of stocks to the Department of Defense; and $3.5 billion for Israel to purchase U.S. weapons.
"The House must pass the package this week and the Senate should quickly follow," President Joe Biden said in a statement. "I will sign this into law immediately to send a message to the world: We stand with our friends, and we won’t let Iran or Russia succeed."
Votes are expected in the House on Thursday, Friday and Saturday.
Netanyahu: Israel 'will make our own decisions' on how to respond to Iran
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.

'Majority' of intel came from coalition partners ahead of attack: Israeli Air Force official
A senior Israeli Air Force official said that the normalization of relations with Middle Eastern countries "served us during this crucial time" this weekend.
"It has to be clear that real assets" provided Israel with "information" and an "early warning," and the "majority" of that intelligence came from the coalition, the senior Israeli Air Force official said at a Monday briefing.
In terms of the types of drones and missiles used by Iran in the Saturday night attack, the official said Israel did not face any types of missiles that it had not shot down during attacks in recent months by Iranian proxies.
The official confirmed that only "a handful" of ballistic missiles fired by Iran were not intercepted.
"Five, more or less, managed to penetrate," the official said.
He said Israel's "strategic investment" in air defense capabilities, made years ago, had paid off, and called Israel shooting down nearly all missiles a "historic success."
The official was asked if Israel would be able to withstand a similar level of attack from Iran, without the support of allies such as the U.S.
"It would be more challenging,” the official conceded, but added that Israel has capabilities "to face this kind of challenge."
