Trump said the U.S. attacked three nuclear sites in Iran.
The United States struck three nuclear sites in Iran on Saturday, President Donald Trump announced.
B-2 bombers dropped a number of Massive Ordnance Penetrator bombs -- known as "bunker busters" -- during the U.S. mission over Iran, a U.S. official confirmed.
A number of Tomahawk cruise missiles were also fired at targets inside Iran from a U.S. Navy submarine, the official confirmed.
Following the strikes, Trump addressed the nation, calling it a "spectacular military success."
The Israel Defense Forces issued a warning to residents in District 3 of Tehran to "immediately leave" ahead of planned strikes there.
"In the coming hours, the Israeli army will take action in this area to attack the Iranian regime's military infrastructure, just as it has done in recent days around Tehran," a post to the IDF's Farsi-language X account read.

Israel is "not planning to change the regime in Iran," Israel Defense Forces spokesperson Brig. Gen. Effie Defrin told ABC News' Ian Pannell in Tel Aviv on Monday.
"Our military targets, our military goals are to remove this threat, to remove the threat of a nuclear bomb over Israel and the ballistic missiles, and of course the proliferation of terror all over the region," Defrin said.
"It's up to the Iranian people to change the regime, not to us," Defrin said. "We are removing this threat. This is why we paved the way to Iran."
Asked about the growing toll on Israeli civilians as Iran retaliates, Defrin said, "Can you imagine what would have happened if this happens when Iran has nuclear capabilities?" He then suggested that Israel had "only a matter of days" in which to prevent such a development.
Attacks in Iran, Defrin continued, will go on for "as far as we're concerned."

Israel's control of the airspace over Tehran represents a "change in the entire" military "campaign," Israeli Prime Minister Benjamin Netanyahu said in comments on Monday.
"When we control the skies over Tehran, we are striking these goals, the regime's targets, in contrast to the criminal regime of Iran that targets our citizens and comes to kill children and women," Netanyahu said.
"We are telling the citizens of Tehran: 'Get out' -- and we are acting," Netanyahu said.
At least 224 people have been killed in Iran since Israel launched its first strikes there on Friday, according to Iranian authorities. At least 24 people have been killed by Iranian retaliatory strikes in Israel, according to Netanyahu's office.
Iran and Israel have both accused the other of striking civilian targets.
