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.

Biden speaks with Jordanian king as G7 leaders condemn Iranian attack
President Joe Biden and Jordanian King Abdullah II spoke on the phone Sunday about Iran's attack on Israel, according to the White House.
The two leaders discussed Iran's "unprecedented attack" on Israel, the White House said without elaborating.
Earlier Sunday, Biden met with G7 leaders, who jointly condemned Iran's attack on Israel.
"We, the Leaders of the G7, unequivocally condemn in the strongest terms Iran’s direct and unprecedented attack against Israel. Iran fired hundreds of drones and missiles towards Israel. Israel, with the help of its partners, defeated the attack," the G7 leaders said in a joint statement.
The statement added, "We express our full solidarity and support to Israel and its people and reaffirm our commitment towards its security."
The G7 leaders said the actions of Iran "further stepped toward the destabilization of the region and wrists provoking uncontrollable regional escalation."
"We demand that Iran and its proxies cease their attacks, and we stand ready to take further measures now and in response to further destabilizing initiatives," the statement said.
