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.
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.
President Joe Biden told reporters he expects an Iranian strike on Israel to occur "sooner than later."
Asked for his message to Iran in this moment, Biden was blunt, saying simply: "Don't."
Asked by ABC News if the U.S. would respond, he said, "We are devoted to the defense of Israel. We will support Israel. We will help defend Israel and Iran will not succeed."

U.S. officials continue to see indicators that Iran could be ready to attack Israel with missile and drone strikes.
Iran has readied a large number of missiles for a possible strike, according to three U.S. officials. Two of the officials said that Iran has readied more than 100 cruise missiles for a possible strike. Iran has also readied a sizeable number of drones that could be used in an attack on Israel, according to one official.
The officials said that Iran has been readying the missiles and drones over the last week.

At least one person is dead and 18 others injured after Israeli settlers allegedly stormed the village of Al-Mughayir in the West Bank, according to the Palestinian Health Ministry.
Some 1,500 settlers burned more than 40 homes and vehicles in the village, according to Marzouq Abu Naim, the deputy mayor of the Al-Mughir Village Council.
The Israel Defense Forces said that "violent riots" erupted in the area while forces searched for a missing 14-year-old boy.
"During the incident, rocks were hurled at IDF soldiers, who responded with fire. Hits were identified," the IDF said in a statement. "Furthermore, IDF and Israel Border Police forces operated to withdraw Israeli civilians who entered the town of Al Mughayyir."
The crowds have since dispersed and there are no longer any Israeli civilians present within the town, the IDF said.
The European Union has sanctioned three terrorist group wings for "widespread sexual and gender-based violence" that occurred in Israel on Oct. 7, the EU Council said.
The sanctioned entities are the Al-Quds Brigades, the armed wing of the Palestinian Islamic Jihad; Nukhba Force, a Hamas special forces unit; and the Qassam Brigades, Hamas' military wing. The Palestinian Islamic Jihad and Hamas are designated as terrorist organizations by the EU.
"Those listed under the sanctions regime are subject to an asset freeze, and the provision of funds or economic resources, directly or indirectly, to them or for their benefit, is prohibited," the EU Council said.
