The IDF said it is currently striking "surface-to-surface missile sites."
Aerial attacks between Israel and Iran continued overnight into Monday, marking a fourth day of strikes following Israel's Friday attack. That surprise strike hit the heart of Iran's nuclear program, killing several nuclear scientists as well as high-ranking military leaders, according to Israeli officials.
The U.S. did not provide any military assistance or have any involvement in Israel's Friday strike, a U.S. official told ABC News. President Donald Trump told ABC News on Sunday, "It's possible we could get involved."
In a statement early Friday morning, Israeli Prime Minister Benjamin Netanyahu released a statement calling the strikes "successful."
Translated from Hebrew, Netanyahu said, "We are after a very successful opening strike. With God's help, we are going to have many more achievements."
Top House Republican leaders are voicing support for Israel’s strikes on Iran.
Speaker Mike Johnson posted an Israeli flag on X and said, "Israel IS right—and has a right—to defend itself!
Majority Leader Steve Scalise said he stands with Israel.
"Iran has refused to dismantle its nuclear program, which puts America at risk and poses an existential threat to Israel. Tonight Israel is taking action to defend itself, and we stand with Israel. Our prayers are with them and all American personnel in the region," Scalise said in a post on X.
Echoing Trump administration officials, House Armed Services Committee Chairman Mike Rogers said the U.S. was not involved in the strikes.
"The U.S. was not involved in the strikes, but our forces stand ready to defend themselves and our ally Israel," Rogers said in a statement.

The head of Iran's Islamic Revolutionary Guard Corps Gen. Hossein Salami was killed in Israeli strikes on Iran, Iranian state TV reports.
Also killed was Dr. Fereydoun Abbasi, former head of the Atomic Energy Organization, according to Iranian state TV.
Israel has not confirmed the deaths.
A senior security official said, "There is a growing likelihood that the Iranian General Staff, including the Iranian Chief of Staff, and senior nuclear scientists were eliminated in the opening blow."
During a televised address, Israel Defense Forces Chief Eyal Zamir said the military was calling up "tens of thousands of soldiers" and was "prepared across all borders." The official went on to say, "I warn that anyone who will try to challenge us, will pay a heavy price."
