President Trump revealed on Saturday that the United States conducted airstrikes on three Iranian nuclear sites, one of which includes the Fordow facility nestled within a mountainside.

In his announcement on Truth Social, Trump stated, “We have successfully executed our attack on the three Nuclear sites in Iran: Fordow, Natanz, and Esfahan.”

He further added, “All aircraft have exited Iran’s airspace. We delivered a full payload of bombs on our primary target, Fordow. All planes are now safely returning home. Kudos to our exceptional American Warriors. There is no other military worldwide capable of such a feat. NOW IS THE TIME FOR PEACE!”

The announcement of U.S. action against Iran came two days after the White House said Trump would decide whether to get involved in the conflict between Iran and Israel “in the next two weeks” to give a window for negotiations.

Trump later said on Truth Social that he planned to give a nationwide address at 10 p.m. EDT Saturday.

It was not immediately clear if the U.S. had deployed specialized “bunker-buster” bombs that experts said could penetrate the mountain where Fordow is located.

Israel had struck Iranian nuclear facilities earlier this month, killing multiple top Iranian military officials in the process. That attack set off a series of retaliatory strikes from Tehran.

While the U.S. was not involved in Israel’s initial missile strikes, all eyes were on Trump and whether he would get directly involved. 

Trump has been adamant that Iran could not be allowed to develop a nuclear weapon, and he indicated Tehran would not be allowed to enrich uranium as part of any deal.

But some members of his base, including Rep. Marjorie Taylor Greene (R-Ga.) and Steve Bannon, had cautioned against U.S. involvement in a foreign conflict, arguing it would not align with Trump’s America First platform.
