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."
"Dozens of missiles" were launched from Iran toward Israel in the past hour, the Israel Defense Forces said in a post on X about 10 minutes ago.
"Some of the missiles were intercepted," the IDF said.
Search and rescue forces are operating in "a number of locations" across Israel, the IDF added.
The IDF has instructed that people can leave shelters but should stay close to them.

Speaking at the UN Security Council Friday, Israel's UN Ambassador Danny Danon defended Israel’s decision to take military action against Iran as an "act of national preservation," insisting it had no other option.
"This operation was carried out because the alternative was unthinkable. How long did the world expect us to wait?" Danon asked. "Until they assembled the bomb? Until they mounted it on a Shahab missile? Until it was en route to Tel Aviv or Jerusalem, like the more than 100 missiles that descended an hour ago? How long should we wait?"
He concluded: "Empty words will not stop Iran. Israel will. We will not wait for the bomb to fall."
