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."
The IDF says Iran has launched more missiles toward Israel and that "defensive systems are operating to intercept the threat."
"The public is instructed to enter a protected space and remain there until further notice," the IDF statement said.
Sources tell ABC News that flashes were seen and booms heard in the skies over Tel Aviv.

The IDF says it struck an Iranian refueling plane at the Mashhad airport in eastern Iran, which makes this, it says, the farthest strike into Iran since attacks began.
"At a distance of approximately 2,300 kilometers, the Air Force struck an Iranian refueling aircraft a short time ago at Mashhad Airport in eastern Iran," the IDF statement says. "The Air Force is working to achieve air superiority throughout Iran. This is the farthest strike since the operation began."
President Donald Trump told ABC News that "it's possible we could get involved" in the ongoing conflict between Israel and Iran.
The president made the comments to ABC News' Rachel Scott. He also reiterated that the U.S. is "not at this moment involved" in the conflict.
Trump also said that he would be "open" to Russian President Vladimir Putin being a mediator in the conflict. "He is ready. He called me about it. We had a long talk about it, " Trump said.

The IDF says missiles have been launched from Iran toward Israel and that "defensive systems are operating to intercept the threat." It also warned citizens to "enter a protected space and remain there until further notice."
The IDF said during a briefing Sunday that it has struck "over 250 targets" in Iran since the beginning of strikes earlier this week. It says it is still actively conducting strikes in the country.
The IDF spokesperson also confirmed it struck Yemen Saturday night, targeting a Houthi leader, but cannot confirm whether the strike was successful. There were also projectiles fired from Yemen overnight toward Israel, according to the spokesperson.
The spokesperson warned that "there will be further launches and impacts in the coming days" toward Israel and advised Israelis to pay attention to sirens and alerts.
