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.
Britain launches Royal Air Force aircraft to intercept attacks on Israel
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."

US 'carefully' reviewing Israel's report on WCK attack, Blinken says
U.S. officials are reviewing Israel's report on the Israel military’s attack on World Central Kitchen aid workers "very carefully" and "will be discussing its conclusions with Israeli officials and with humanitarian organizations in the days to come," Secretary of State Antony Blinken told reporters.
The Israel Defense Forces said its airstrike in Gaza that killed seven WCK aid workers on Monday came after Israeli forces misidentified a WCK worker in the convoy as a Hamas gunman.
Blinken said Israeli Prime Minister Benjamin Netanyahu "indicated" to President Joe Biden in their Thursday call "that Israel would be making further changes to its procedures to make sure that those who are providing assistance to people who so desperately need it in Gaza are protected."
"It's very important that Israel is taking full responsibility for this incident. It's also important that it appears to be taking steps to hold those responsible accountable," Blinken said. "Even more important is making sure that steps are taken going forward to ensure that something like this can never happen again."
Blinken said the U.S. would be "looking to see not just what steps are being taken, but the results that follow" from potential changes to Israeli military operations.
