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."
U.S. government employees in Israel are still directed to shelter in place, with no plans to evacuate Americans or help with departures at this point.
"Ben Gurion Airport is currently closed, and there are no commercial or charter flights operating from there. Land crossings to Jordan are currently operating (although they are closed on Saturdays)," the government said.

It's unlikely the sixth round of talks between the U.S. and Iran on a potential nuclear deal will happen this weekend in Oman, Iranian Member of Parliament Alaeddin Boroujerdi said on Iranian TV Friday.
"We are on the verge of the sixth round, which I don't think will happen with these developments, because they have, in fact, shown their entry into our red lines. Therefore, I think this is in connection with the nuclear issue," Boroujerdi said, in an interview in Farsi.
Boroujerdi said Iran entered into the negotiations with a "fair amount of open-mindedness at the request of the United States."
U.S. Special Envoy to the Middle East Steve Witkoff had been scheduled to meet with Iranian officials on Sunday prior to the overnight attacks.
Israel's attacks on Iran can be expected to last for days, maybe even weeks, an Israel Defense Forces official told ABC News. The goal is to get the job done, the source said, which means destroying Iran's nuclear capability and missile arsenal.
Israel has complete control over the skies in Iran, having denuded the country of its air defenses in the previous two attacks last year, the source said.
The reason Iran hasn't launched missiles in reprisal is not because it's biding its time, but it's because Israel has destroyed the missiles that were ready for launch, according to the source.
The source underscored that 200 or so Israeli jets flew a 2,000 mile round trip over other semi-hostile nations, like Syria and Iraq, without a single mishap and without a single casualty.
