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.

In meeting with Israelis, US officials 'expressed concerns' over Rafah
In a Thursday meeting between U.S. and Israeli officials, the two sides discussed the attack by Iran as well as the Israeli military's plans for an operation in Rafah in Gaza, according to the White House.
During the meeting, the "U.S. participants expressed concerns with various courses of action in Rafah," according to a White House readout.
"Israeli participants agreed to take these concerns into account and to have further follow up discussions between experts, overseen by the U.S.-Israel Strategic Consultative Group," and the officials agreed to meet again "soon," according to the White House.
National security adviser Jake Sullivan convened the meeting and the Israeli side was led by Minister for Strategic Affairs Ron Dermer and national security adviser Tzachi Hanegbi.
Iran attack 'thwarted' but 'event is not over,' Israel says
Israeli military officials on Sunday said the Iranian attack had been "thwarted" by Israel and its allies, but warned that the threat of further strikes continued.
Most of the more than 300 drones, missiles and other threats Iran launched were intercepted by Israeli and allied defenses before entering Israel, the Israel Defense Forces said.
"99% of the threats launched towards Israeli territory were intercepted -- a very significant strategic achievement," IDF spokesperson Daniel Hagari said.
The military defense was coordinated with a group of international allies, including the United States, United Kingdom and France, Hagari said.
"This partnership has always been robust, but last night it was exceptionally evident," he said.
The attack included at least 170 uncrewed drones, none of which made it into Israeli territory, he said.
About 25 of the 30 cruise missiles launched were intercepted by Israeli fighter jets before entering Israel, Hagari said.
And more than 120 ballistic missiles were launched, with "only a few" striking targets within Israel, he said. Those that made it through struck Nevatim Air Force Base, causing "minor damage to infrastructure," he said. The base remained open, he added.
"However, it is important to say -- the event is not over," Hagari said. "We remain prepared and ready for further developments and threats."
