Washington — The United States launched strikes on three Iranian nuclear facilities, President Trump announced Saturday evening, calling them a “spectacular military success.”
“We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan,” Mr. Trump wrote on Truth Social. “All planes are now outside of Iran air space. A full payload of BOMBS was dropped on the primary site, Fordow. All planes are safely on their way home. Congratulations to our great American Warriors. There is not another military in the World that could have done this. NOW IS THE TIME FOR PEACE! Thank you for your attention to this matter.”
In a follow-up post, Mr. Trump wrote: “This is an HISTORIC MOMENT FOR THE UNITED STATES OF AMERICA, ISTAEL (sic), AND THE WORLD. IRAN MUST NOW AGREE TO END THIS WAR. THANK YOU!”
The president addressed the nation regarding the strikes late Saturday night, saying that “Iran’s key nuclear enrichment facilities have been completely and totally obliterated” and issuing a warning to Iran to strive for a peace deal in its war with Israel.
“There will be either peace, or there will be tragedy for Iran far greater than we have witnessed over the last eight days,” Mr. Trump said. “Remember, there are many targets left.”
Mr. Trump added that “if peace does not come quickly, we will go after those other targets with precision, speed and skill. Most of them can be taken out in a matter of minutes.”
Iran has pledged to retaliate if the U.S. joined the Israeli assault, which began with airstrikes on Iranian nuclear sites and military targets on June 13. Iran has responded with missile and drone attacks on Israeli cities.
Fordo, the site of an enrichment facility that international experts believe is key to Iran’s nuclear program, is buried almost 300 feet beneath a mountain and protected by significant air defenses.

Experts have believed the best chance at destroying the facility lies with the U.S.-produced “bunker-buster” bomb known as the GBU-57 Massive Ordnance Penetrator, or MOP — a bomb so heavy that it could only be dropped by an American B-2 bomber.
A source familiar with the operation and a senior Defense Department official confirmed that the MOP was used in the strikes, with two MOPs used per target. However, a senior Defense Department official later told CBS News that three B-2s were used to strike Fordo, with each of those B-2s armed with 2 MOPs.
The U.S. reached out to Iran diplomatically Saturday to say the strikes are all the U.S. plans and that regime change efforts are not planned, the sources said. Earlier this week, multiple U.S. officials told CBS News that Mr. Trump opposed an Israeli plan to kill Ayatollah Ali Khamenei, Iran’s supreme leader.
The U.S. alerted Israel ahead of the strikes, two White House officials told CBS News. Mr. Trump and Israeli Prime Minister Benjamin Netanyahu spoke following the strikes, the officials said. And in a video address, Netanyahu praised the president for conducting the strikes.
“President Trump and I often say peace through strength. First comes strength, then comes peace. And tonight President Trump and the United States acted with a lot of strength.”
According to the Iranian state media outlet IRNA, Morteza Heidari, a spokesman for crisis headquarters in Iran’s Qom province, acknowledged there had been attacks on all three nuclear sites.
House Speaker Mike Johnson was briefed ahead of the strikes, according to a source familiar.
Earlier Saturday, multiple U.S. officials had confirmed to CBS News that B-2 bombers had departed Whiteman Air Force Base in Missouri en route to Guam. Multiple U.S. aerial refueling tankers were spotted on commercial flight trackers flying flight patterns consistent with escorting aircraft from the central U.S. to the Pacific.
The U.S. strikes come after Iranian Foreign Minister Abbas Araghchi met with European officials in Geneva Friday and said he was open to further dialogue.
“Iran is ready to consider diplomacy once again,” Araghchi said, adding, “I stress that Iran’s defense capabilities are not negotiable. (But) I express our readiness to meet again in the near future.”
On Thursday, the president said he would decide whether to strike Iran “within the next two weeks.” One source told CBS News at the time that Mr. Trump “believes there’s not much choice. Finishing the job means destroying Fordo.”
Meanwhile, U.S. Ambassador to Israel Mike Huckabee said earlier Saturday that the U.S. had begun evacuating Americans and green card holders out of Israel aboard assisted departure flights. Two flights departed from Tel Aviv to Athens with approximately 70 U.S. citizens, their accompanying immediate family members and lawful permanent residents, the State Department said prior to Mr. Trump’s announcement of the strikes.
Homeland Security officials are monitoring for potential physical and cyber reprisals from the U.S. attack, domestically amid a “very high” threat level and with the “red line” of the Iranian response doctrine now crossed, CBS News has learned.
“We’re in unchartered territory,” one U.S. intelligence official told CBS News, while speaking about potential Iranian threats to the U.S. homeland. “We don’t know how Iran will react to this because this is the highest rate of tension and conflict we’ve had in recent history. We’re just not sure how the Khomeini regime will react.”
The official added that assessments range from little to no action on the part of Iranians to desperate and drastic action.
