Trump says US carried out 'very successful attack' on three Iran nuclear sites

President Donald Trump said Saturday the US military has carried out a "very successful attack" on three Iranian nuclear sites, including the crucial underground uranium enrichment facility at Fordo.

Trump said a "full payload of BOMBS" was dropped on Fordo, in a surprise announcement that came just two days after he had apparently opened a two-week window for diplomacy.

In a public video address, US President Donald Trump hailed the US's attack on Iran, calling it a "spectacular military success", adding that Iran's sites have been "completely and fully obliterated".

He added that their "objective was the destruction of Iran's nuclear enrichment capacity and a stop to the nuclear threat posed by the world's number one state sponsor of terror".

Trump justified the attacks over Iran, calling for the "death to America" and being a "bully" in the Middle East.

"They [Iran] have been killing our people, blowing off their arms, blowing off their legs, with roadside bombs. That was their specialty, we lost over 1,000 people," Trump said.

"I decided a long time ago that I would not let this happen. It will not continue."

The president threatened the nation, warning that if it did not make peace, it would "go after" other targets.

"With all of that being said, this cannot continue. There will be either peace or there will be tragedy for Iran far greater than we have witnessed over the last eight days," Trump said.

"There will be either peace or there will be tragedy for Iran worse than what we've witnessed."

"If they do not, future attacks will be far greater, and a lot easier," added Trump, who was flanked by Vice President JD Vance, Defence Secretary Pete Hegseth and Secretary of State Marco Rubio for his address on Saturday evening for US audiences.

"We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan," Trump said in a post on his Truth Social platform.

"A full payload of BOMBS was dropped on the primary site, Fordow."

Trump added that "all planes are safely on their way home. Congratulations to our great American Warriors."

In a second post announcing his address to the nation from the White House, Trump said that "IRAN MUST NOW AGREE TO END THIS WAR."

He also described it as a "historic" moment for the United States, Israel and the world.

Trump's shock announcement came just two days after he said he would decide "within two weeks" whether to join key ally Israel in attacking Iran.

Iranian media said on Sunday that part of the Fordo uranium enrichment facility, as well as the Isfahan and Natanz nuclear sites, were attacked, after Donald Trump said the US had bombed them.

"A few hours ago, after Qom's air defenses were activated and hostile targets were identified, part of the Fordo nuclear site was attacked by enemy airstrikes," Tasnim news agency reported, quoting Morteza Heydari, spokesperson for the Qom Provincial crisis management department.

Separately, Fars news agency said: "The air defenses of Isfahan and Kashan began to work to counter hostile targets, and several explosions were heard simultaneously."

The agency has also confirmed that the US attacked Natanz and Isfahan.

"We witnessed attacks near the nuclear centres of Isfahan and Natanz," Akbar Salehi, an aide to the governor of Isfahan, said.

Iran's atomic energy organisation condemned Sunday the US attacks on key nuclear sites, including the mountain-buried Fordo, as "barbaric" and in violation of international law.

"At dawn today, the country's nuclear sites in Fordo, Natanz and Isfahan were attacked by the enemies of Islamic Iran in a barbaric act that violates international law," the organisation said in a statement published on state media.

Earlier on Saturday, there were reports that US B-2 bombers, which carry so-called "bunker buster" bombs, were headed out of the United States.

Trump did not say what kind of US planes or munitions were involved.

Tehran had threatened reprisals on US forces in the Middle East if Trump attacked, but the US president said that "NOW IS THE TIME FOR PEACE!"

Israel was reportedly “in full coordination with the US” during the US's attacks on Iran, Israeli public broadcaster Kan said, citing an anonymous Israeli official.

Israeli Prime Minister Benjamin Netanyahu released a video statement thanking Trump's "historic" decision on attacking Iran, saying the US "acted with a lot of strength".

"Congratulations, President Trump. Your bold decision to target Iran's nuclear facilities with the awesome and righteous might of the United States will change history," Netanyahu said.

Trump said the US and Israel “worked as a team” and have “gone a long way to erasing this horrible threat to Israel”.

Ro Khanna from the Democratic Party says the president struck Iran without authorisation from the US Congress.

“Trump struck Iran without any authorization of Congress,” Khanna said in a social media post.
