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 closes schools, limits gatherings ahead of anticipated Iranian attack

As part of the changes, schools and educational institutions will remain closed across Israel, "prohibiting educational activities," -- not only because the Passover vacation is starting. Gatherings will be limited to 1,000 people in green areas.

Ship seized by Iran in 'pirate operation' is Portuguese, Israel says
In a statement in response to Iran's seizure of a cargo ship it said was Israeli, Israeli Foreign Minister Israel Katz claimed it was a Portuguese civilian cargo ship, belonging to an EU member.
Katz called Iran's seizing of the cargo ship "a pirate operation in violation of international law". He also called Iran's "Ayatollah regime" a "criminal regime".
"The Ayatollah regime of @khameneiir is a criminal regime that supports Hamas' crimes and is now conducting a pirate operation in violation of international law. I call on the European Union and the free world to immediately declare the Iranian Revolutionary Guards corps as a terrorist organization and to sanction Iran now," Katz said in a statement.

Palestinian man killed after Israeli boy goes missing, found dead in West Bank
A Palestinian man has been killed in the occupied West Bank and 25 are reported hurt after dozens of Jewish settlers stormed a village during an Israeli search for a missing teenager. Israeli troops intervened after dozens of settlers stormed al-Mughayyir armed with guns and stones.
It is not yet clear whether the man who died, Jehad Abu Alia, 26, was shot by an armed settler or Israeli soldier. The Palestinian Red Crescent said live fire hit at least eight people.
The missing boy, identified as Benjamin Ahimeir, 14, was found dead. He had gone missing Friday morning before Israeli officials say he was killed in a "terror attack."
"Security forces are continuing the pursuit after those suspected of carrying out the attack," the Israel Defense Forces said Saturday.
