U.S. strikes three Iranian sites, joining Israeli air campaign against nuclear program

The U.S. military struck three sites in Iran early Sunday, directly joining Israel ’s war aimed at decapitating the country’s nuclear program amid Tehran’s threat of reprisals that could spark a wider conflict.

Iran’s state-run IRNA news agency reported that attacks targeted the country’s Fordo, Isfahan and Natanz nuclear sites. The agency did not elaborate.

This comes after more than a week of strikes by Israel on Iran that aimed to eradicate the country’s air defenses and offensive missile capabilities, while damaging its nuclear enrichment facilities. But U.S. and Israeli officials have said that American stealth bombers and the 30,000-pound bunker buster bomb they alone can carry offered the best chance of destroying heavily fortified sites connected to the Iranian nuclear program buried deep underground.

“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 social media. “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.”

Trump wrote “This is an HISTORIC MOMENT FOR THE UNITED STATES OF AMERICA, ISRAEL, AND THE WORLD. IRAN MUST NOW AGREE TO END THIS WAR. THANK YOU!”

Trump told reporters Friday that he was not interested in sending ground forces into Iran, saying it’s “the last thing you want to do.” He had previously indicated that he would make a final choice over the course of two weeks.

Iran’s Supreme Leader Ayatollah Ali Khamenei warned the United States on Wednesday that strikes targeting the Islamic Republic will “result in irreparable damage for them.” And Iranian Foreign Ministry spokesman Esmail Baghaei declared “any American intervention would be a recipe for an all-out war in the region.”

Trump has vowed that he would not allow Iran to obtain a nuclear weapon, and he had initially hoped that the threat of force would bring the country’s leaders to give up its nuclear program peacefully.

The Israeli military said Saturday it was preparing for the possibility of a lengthy war, while Iran’s foreign minister warned before the U.S. attack that American military involvement “would be very, very dangerous for everyone.”

The prospect of a wider war loomed. Iranian-backed Houthi rebels in Yemen said they would resume attacks on U.S. vessels in the Red Sea if the Trump administration joined Israel’s military campaign. The Houthis paused such attacks in May under a deal with the U.S.

The U.S. ambassador to Israel announced that the U.S. had begun “assisted departure flights,” the first from Israel since the Hamas-led attack on Oct. 7, 2023, that sparked the war in Gaza.

Trump appears to have made the calculation — at the prodding of Israeli officials and many Republican lawmakers — that Israel’s operation had softened the ground and presented a perhaps unparalleled opportunity to set back Iran’s nuclear program, perhaps permanently.

The Israelis say their offensive has already crippled Iran’s air defenses, allowing them to already significantly degrade multiple Iranian nuclear sites.

To destroy the Fordo nuclear fuel enrichment plant, Israel appealed to Trump for the bunker-busting American bomb known as the GBU-57 Massive Ordnance Penetrator, which uses its weight and sheer kinetic force to reach deeply buried targets and then explode. The bomb is currently delivered only by the B-2 stealth bomber, which is only found in the American arsenal.

If deployed in the attack, it would be the first combat use of the weapon.

The bomb carries a conventional warhead, and is believed to be able to penetrate about 200 feet below the surface before exploding, and the bombs can be dropped one after another, effectively drilling deeper and deeper with each successive blast.

The International Atomic Energy Agency has confirmed that Iran is producing highly enriched uranium at Fordo, raising the possibility that nuclear material could be released into the area if the GBU-57 A/B were used to hit the facility.

Previous Israeli strikes at another Iranian nuclear site, Natanz, on a centrifuge site have caused contamination only at the site itself, not the surrounding area, the IAEA has said.

The military showdown with Iran comes seven years after Trump withdrew the U.S. from the Obama-administration brokered agreement in 2018, calling it the “worst deal ever.”

The 2015 deal, signed by Iran, U.S. and other world powers, created a long-term, comprehensive nuclear agreement that limited Tehran’s enrichment of uranium in exchange for the lifting of economic sanctions.

Trump said the Obama-era deal for giving Iran too much in return for too little, because the agreement did not cover Iran’s non-nuclear malign behavior.
