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.
Flights to Tehran, Isfahan and Shiraz have been suspended following reports an explosion was heard in the city of Qahjavaristan, Iranian state media reported.
The city of Qahjavaristan is located near Isfahan Airport and the 8th Shekhari Base of the Army Air Force in the northwest of Isfahan.

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.
Israel has made significant progress in preparations for the evacuation of around 1 million civilians from Rafah ahead of the Israeli military’s impending operation in the southern Gaza city, according to an Israeli source.
Preparations have been ongoing for over a month, including repairing water and sewage pipes and amassing thousands of tents, the source said.
There are around 1.5 million Palestinians estimated to be in the Khan Younis and Rafah areas in southern Gaza. It’s believed around 1 million people would evacuate north. The evacuation process, which could take weeks, would not start until after Passover.
State Department principal deputy spokesperson Vedant Patel stressed to reporters that "any kind of forced relocation or displacement of the Palestinian people within Gaza cannot and should not be part of any plan or an operation."
