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.

This beats the record that was set one day earlier, when 322 trucks entered Gaza.
Israeli military submitted a 'spectrum of response options' to the government
Israeli military officials have submitted "a wide range of options" to respond to Iran’s missile strike Saturday, Israeli Defense Federation (IDF) spokesperson Peter Lerner told reporters early Monday morning in Tel Aviv.
The IDF’s response could be "strike or no strike," according to Lerner, who noted, there are "a lot of different scenarios in between those two."
The Israeli government will "decide on the steps forward" as early as Monday or within the coming days, Lerner said.
When asked about Iran’s "substantial" missile strike being intercepted with minimal damage, Lerner said, "Just because we were successful in intercepting, we shouldn't underestimate what Iran did."
"We can't take that lightly," Lerner said.
