What to know about the Iranian nuclear sites that were hit by US strikes
DUBAI, United Arab Emirates (AP) — U.S. forces have attacked three Iranian nuclear and military sites, further upping the stakes in the Israel-Iran war.
President Donald Trump said the strikes, which he described as 'very successful,' had hit the Natanz, Fordo and Isfahan sites, with Fordo being the primary target. The Atomic Energy Organization of Iran confirmed there were attacks early Sunday at all three nuclear sites.
Israel launched a surprise barrage of attacks on sites in Iran on June 13, which Israeli officials said was necessary to head off what they claimed was an imminent threat that Iran would build nuclear bombs.
Iran, which has long insisted its nuclear program is peaceful, has retaliated with a series of missile and drone strikes in Israel, while Israel has continued to strike sites in Iran.
The U.S. and Iran had been in talks that could have resulted in the U.S. lifting some of its crushing economic sanctions on Iran in exchange for Tehran drastically limiting or ending its enrichment of uranium. Until Saturday, Washington had helped shoot down Iranian strikes on Israel but had not launched direct attacks on Iran.
Here's a look at the sites Trump said the U.S. struck and their importance to Iran's nuclear program.
Natanz enrichment facility
Iran's nuclear facility at Natanz, located some 220 kilometers (135 miles) southeast of Tehran, is the country's main enrichment site and had already been targeted by Israeli airstrikes. Uranium had been enriched to up to 60% purity at the site — a mildly radioactive level but a short step away from weapons grade — before Israel destroyed the aboveground part of the facility, according to the U.N.'s nuclear watchdog, the International Atomic Energy Agency.
Another part of the facility on Iran's Central Plateau is underground to defend against potential airstrikes. It operates multiple cascades, or groups of centrifuges working together to more quickly enrich uranium. The IAEA has said it believes that most if not all of these centrifuges were destroyed by an Israeli strike that cut off power to the site.
The IAEA said those strikes caused contamination only at the site itself, not the surrounding area.
Iran also is burrowing into the Kūh-e Kolang Gaz Lā, or Pickax Mountain, which is just beyond Natanz's southern fencing. Natanz has been targeted by the Stuxnet virus, believed to be an Israeli and American creation, which destroyed Iranian centrifuges. Two separate attacks, attributed to Israel, also have struck the facility.
Fordo enrichment facility
Iran's nuclear facility at Fordo is located some 100 kilometers (60 miles) southwest of Tehran. It also hosts centrifuge cascades, but isn't as big as Natanz. Its construction began at least in 2007, according to the IAEA, although Iran only informed the U.N. nuclear watchdog about the facility in 2009 after the U.S. and allied Western intelligence agencies became aware of its existence.
Buried under a mountain and protected by anti-aircraft batteries, Fordo appears designed to withstand airstrikes. Military experts have said it could likely only be targeted by 'bunker buster' bombs — a term for bombs that are designed to penetrate deep below the surface before exploding — such as the latest GBU-57 A/B Massive Ordnance Penetrator bomb in the American arsenal. The roughly 30,000 pound (13,600 kilogram) precision-guided bomb is designed to attack deeply buried and hardened bunkers and tunnels.
The U.S. has only configured and programed its B-2 Spirit stealth bomber to deliver that bomb, according to the Air Force. The B-2 is only flown by the Air Force, and is produced by Northrop Grumman, meaning that Washington would have to be involved in such an operation.
Isfahan Nuclear Technology Center
The facility in Isfahan, some 350 kilometers (215 miles) southeast of Tehran, employs thousands of nuclear scientists. It also is home to three Chinese research reactors and laboratories associated with the country's atomic program.
Israel has struck buildings at the Isfahan nuclear site, among them a uranium conversion facility. The IAEA said there has been no sign of increased radiation at the site.
Other nuclear sites
Iran has several other sites in its nuclear program that were not announced as targets in the U.S. strikes.
Iran's only commercial nuclear power plant is in Bushehr on the Persian Gulf, some 750 kilometers (465 miles) south of Tehran. Iran is building two other reactors like it at the site. Bushehr is fueled by uranium produced in Russia, not Iran, and is monitored by the IAEA.
The Arak heavy water reactor is 250 kilometers (155 miles) southwest of Tehran. Heavy water helps cool nuclear reactors, but it produces plutonium as a byproduct that can potentially be used in nuclear weapons. Iran had agreed under its 2015 nuclear deal with world powers to redesign the facility to relieve proliferation concerns.
The Tehran Research Reactor is at the headquarters of the Atomic Energy Organization of Iran, the civilian body overseeing the country's atomic program. It initially required highly enriched uranium but was later retrofitted to use low-enriched uranium over proliferation concerns.

Trump's approval rating on immigration leads in new poll. What is his approval rating?
Immigration was a flashpoint going into the 2024 presidential election, and it remains President Donald Trump's strongest issue in a recent poll. A NBC News Decision Desk Poll released June 15, conducted along with SurveyMonkey, found that 45% of Americans approve of the way Trump is handling his job as president, while 55% disapprove. Those figures remain unchanged from an NBC News survey in April. (The survey was conducted among 19,410 adults nationwide between May 30 and June 10. It has a margin of error of plus or minus 2.1 percentage points.) According to the survey, 51% of Americans approve of Trump's handling of border security and immigration, while 49% disapprove, the exception to his negative overall rating. Here is what to know about Trump's approval rating and how Americans have reacted to his immigration policies. More: Did Obama deport more people than Trump? What to know as Trump calls for more ICE arrests What do Americans think of Trump's handling of immigration? Trump has focused much of his presidency on advancing his immigration agenda, including deporting thousands of migrants to countries such as Colombia, Mexico and El Salvador. During his 2024 campaign, the sweeping deportations became his signature promise to voters. Here are some other recent polls that show Americans' views of Trump's handling of immigration: What is Trump's approval rating? RealClearPolitics Poll Average shows the gap between Americans who approve of Trump's job and those who disapprove has been largely widening since June 7. Aggregated polls by the New York Times show a similar trend. As of Jan. 27, Trump received a +6.2 percentage point approval rating, but as of March 13, it flipped to slightly negative, the RealClearPolitics graphics shows, and widened over the following weeks until becoming the most negative on April 29 at -7.2 percentage points. His average approval rating margin as of June 20, according to RealClearPolitics, is -5 percentage points. The approval margin according to the New York Times aggregator on June 20 is -8 percentage points. A historical analysis by Gallup shows Trump's approval ratings in May in his first years in office − both as the 45th and 47th presidents − are lower than any other modern president at the same time in their administrations.

Why Trump Has Had Enough of This Republican Congressman
Rep. Thomas Massie (R, Ky.) speaks to reporters after a House GOP caucus meeting at the U.S. Capitol on June 4, 2025. Credit - Kevin Dietsch—Getty Images 'MAGA doesn't want him, doesn't know him, and doesn't respect him,' President Donald Trump wrote in a lengthy tirade against Thomas Massie, a Republican congressman from Kentucky who has criticized the President over a number of issues from war with Iran to the so-called One Big Beautiful Bill. 'He is a negative force who almost always Votes 'NO,' no matter how good something may be. He's a simple minded 'grandstander' who thinks it's good politics for Iran to have the highest level Nuclear weapon, while at the same time yelling 'DEATH TO AMERICA' at every chance they get,' Trump posted on Sunday. He added: 'MAGA should drop this pathetic LOSER, Tom Massie, like the plague!' Massie responded with a tongue-in-cheek post on X that the President 'declared so much War on me today it should require an Act of Congress.' Massie joined last week with a number of Democratic lawmakers to raise the alarm over potential U.S. military intervention in the Middle East without constitutionally-mandated congressional authorization. While Massie won't face a reelection contest until 2026, Trump has already unveiled a plan to challenge him and further enforce loyalty within the GOP ranks. 'The good news is that we will have a wonderful American Patriot running against him in the Republican Primary, and I'll be out in Kentucky campaigning really hard,' Trump added, without naming a prospective primary opponent. 'MAGA is not about lazy, grandstanding, nonproductive politicians, of which Thomas Massie is definitely one.' Massie, who is known for his outspoken libertarian views, has survived primary challenges before and told Axios, which reported on the effort to oust him, that 'any serious person considering running should spend money on an independent poll before letting swampy consultants take them for an embarrassing ride.' Massie, 54, was born in West Virginia and earned bachelor's and master's degrees in engineering from MIT in the 1990s before turning to local politics in 2010, when he ran and won the race for Judge Executive of Lewis County, Ky., amid the Tea Party wave. In 2012, after then-Rep. Geoff Davis announced his retirement in Kentucky's deep-red 4th congressional district, Massie, who described himself as a 'constitutional conservative,' won the Republican primary in a landslide. When Davis resigned early, Massie won the same-day special election and general election to succeed him, taking office two months earlier than his fellow freshmen representatives elected in 2012. One of Massie's first moves was to vote in January 2013 against party leader John Boehner for Speaker, opting instead to vote for fellow libertarian Justin Amash. (Boehner narrowly won the speakership but would go on to resign in 2015. Amash would go on to not run for reelection in 2020 and temporarily leave the Republican Party after earning Trump's wrath for consistent criticism of the President and supporting his impeachment.) Since then, Massie has made a name for himself by regularly voting against bills, often breaking with his caucus and sometimes siding with Democrats. In 2013, Politico dubbed him 'Mr. No.' In 2016, Massie said he would vote for Trump but do everything he could to 'rein him in' if he acts unconstitutionally. In 2017, Massie tried to explain how the same movement that propelled him into office could also propel someone like Trump, telling the Washington Examiner: 'All this time, I thought they were voting for libertarian Republicans. But after some soul searching I realized when they voted for Rand and Ron [Paul] and me in these primaries, they weren't voting for libertarian ideas—they were voting for the craziest son of a b----- in the race. And Donald Trump won best in class.' During Trump's first term, Massie was among a small group of Republicans who joined Democrats in trying to override Trump's veto of legislation that would block his national emergency declaration at the border in 2019. That same year, he was the sole Republican to vote against a resolution opposing the boycott, divestment, and sanctions movement targeting Israel, and he was the sole no-vote across both parties on the Hong Kong Human Rights and Democracy Act. In March 2020, Trump called Massie a 'third rate Grandstander' and urged Republicans to throw him out of the party after the congressman tried to force a roll-call vote on a $2 trillion pandemic relief package. The stunt earned rebuke from both sides of the aisle, with former Democratic presidential nominee and former Secretary of State John Kerry posting on social media: 'Breaking news: Congressman Massie has tested positive for being an a--hole. He must be quarantined to prevent the spread of his massive stupidity.' But in a U-turn, Trump endorsed Massie in 2022, calling him 'a first-rate Defender of the Constitution.' In 2022, Massie was the lone 'No' vote on a symbolic measure condemning antisemitism, a move he defended as a stance against 'censorship' but critics described as 'performative contrarianism.' Massie was once again on Trump's bad side in 2023 when Trump shared posts on his Truth Social platform that called the congressman a 'wolf in sheep's clothing' and said he 'helped destroy the Tea Party and now he's trying to destroy MAGA.' That didn't stop Massie from endorsing Trump in the 2024 general election after previously backing Florida Gov. Ron DeSantis in the Republican primary. But Trump finally had enough of Massie in March, when Massie voted against a continuing resolution to fund the federal government until September as Republicans worked to pass Trump's massive tax-and-spending legislative package, the 'One Big Beautiful Bill' (OBBB). The President took to Truth Social to appeal for a primary candidate to challenge Massie in 2026: 'HE SHOULD BE PRIMARIED, and I will lead the charge against him. He's just another GRANDSTANDER, who's too much trouble, and not worth the fight. He reminds me of Liz Chaney [sic] before her historic, record breaking fall (loss!). The people of Kentucky won't stand for it, just watch. DO I HAVE ANY TAKERS???' Massie brushed off the criticism, telling Politico: 'I had the Trump antibodies for a while — I needed a booster.' He said at the time that he had no intention to cave to Trump's pressure and believed the President's grudge would 'blow over.' When Massie continued to voice loud opposition to the OBBB, which is estimated to add trillions to the national debt, Trump said of Massie in May: 'He doesn't understand government' and 'should be voted out of office.' The OBBB ultimately passed in the House in May, when Massie was one of two Republicans in the lower chamber to vote against it. It has yet to pass in the Senate, especially after Massie found a sympathizer to his concerns about the bill's impact on the deficit in tech billionaire Elon Musk. Trump's latest missive against Massie came as Massie has become a leading voice against military intervention in Iran. Days after Israel launched an attack on Iran, Massie cosponsored a war powers resolution with Rep. Ro Khanna (D, Calif.) aimed at blocking the U.S. government from engaging in 'unauthorized hostilities.' After Trump revealed U.S. strikes on Iranian nuclear facilities, Massie posted on X: 'This is not Constitutional.' While some have categorized Massie's wing of the MAGA base when it comes to the war as 'isolationists,' Massie told CBS on Sunday that he rejects the label, preferring 'non-interventionists.' 'We are exhausted,' he said. 'We are tired from all of these wars.' Trump is dedicating campaign firepower to oust Massie. Axios reported that Trump's senior political advisers, Tony Fabrizio and Chris LaCivita, will launch a political action committee devoted to defeating Massie in the May 2026 primary. LaCivita said the PAC will spend 'whatever it takes' to defeat Massie, who according to the team's internal polling was lagging behind the President in terms of support. As of now, only one candidate, Niki Lee Ethington, has announced that she will vie for Massie's congressional seat. Other names being floated, per Axios, are state senator Aaron Reed and state representative Kimberly Moser. 'Massie's long-time opposition to President Trump's working family tax cuts—and really anything to do with President Trump—is coming to an end,' LaCivita said in a statement. 'Thomas 'Little Boy' Massie will be fired.' Contact us at letters@
