What We Know About the Iranian Nuclear Facilities Targeted in US Strikes

US has launched airstrikes on three key Iranian nuclear facilities, employing stealth bombers and bunker-busting munitions in an operation aimed at supporting Israel's ongoing military campaign against Iran.
The strikes, which began on 13 June, were designed to cripple Tehran's uranium enrichment capabilities and hinder its nuclear ambitions. The Targets: Fordow, Natanz, and Isfahan
The US strikes focused on three of the most critical and advanced sites in Iran's nuclear program: the Fordow enrichment plant, the Natanz nuclear facility, and the Isfahan nuclear complex.
Each of these locations plays a pivotal role in Iran's production and development of nuclear fuel. Fordow Facility
Located approximately 30 kilometers northeast of the city of Qom, the Fordow site is entirely built into a mountain at an altitude of 1,750 meters, shielded by dense rock and volcanic layers—making it one of Iran's most fortified nuclear sites.
The underground facility houses two halls and has the capacity to accommodate around 3,000 IR-1 centrifuges.
It is primarily used to enrich uranium up to 60% purity—just below the weapons-grade threshold.
Fordow has long been seen as a primary military target due to both its technical capabilities and hardened location. Natanz Reactor
Situated near the central Iranian city of Kashan, the Natanz site is protected by a 22-meter-thick combination of earthen and concrete cover and surrounded by mountainous terrain.
It includes both main and pilot enrichment plants and hosts over 14,000 centrifuges of various generations (IR-1, IR-2m, IR-4, and IR-6).
Natanz serves as Iran's main industrial enrichment center, responsible for producing the majority of the country's low-enriched uranium.
It is also central to the research and development of advanced centrifuge technology. Isfahan Nuclear Complex
Located on a barren plateau south of Isfahan city, far from major population centers, the complex is not hardened or underground.
It contains the Uranium Conversion Facility (UCF), a fuel fabrication plant, and three research reactors.
Strategically vital, the Isfahan complex supports both the Natanz and Fordow facilities by supplying essential nuclear materials.
It lies at the heart of Iran's nuclear research and manufacturing infrastructure. Statements from Washington and Tehran
Earlier today, former U.S. President Donald Trump hailed the airstrikes as a major success, claiming they had 'wiped out' Iran's principal nuclear sites.
'Fordow is gone,' Trump declared, adding that the main enrichment installations had been 'completely and utterly destroyed.' He urged Iran to 'choose peace now.'
In contrast, Iranian media outlet Tasnim quoted an unnamed Iranian official who downplayed the impact, stating the nuclear sites had been evacuated in advance and had not sustained irreparable damage.
The Atomic Energy Organization of Iran also assured the public there was 'no risk of radiation leakage' as a result of the strikes.
The US operation marks a dramatic escalation in the conflict, with significant implications for regional stability and the future of Iran's nuclear program.

What do we know about US strikes on Iran's nuclear facilities?

DUBAI: Amid mounting speculation, the US launched air strikes on three of Iran's nuclear facilities on Saturday. The operation aimed to support Israel in its war against Iran — ongoing since June 13 — by crippling Tehran's uranium enrichment capacity, according to Asharq News. US President Donald Trump later announced that Iran's uranium-enrichment abilities had been eliminated, warning Tehran against any 'retaliatory response.' Tehran, however, described the damage as 'limited' and dismissed any indications of radiation leaks. The US strikes included 14 bunker-buster bombs, more than two dozen Tomahawk missiles and over 125 military aircraft, in an operation the top US general, General Dan Caine, said was named 'Operation Midnight.' Asharq News reported that the strikes targeted three critical nuclear facilities instrumental in Iran's nuclear fuel cycle: Fordo, Natanz and Isfahan nuclear complex. These sites span the entire fuel-enrichment chain — from raw uranium conversion, through enrichment, to the production of fuel and technical components for research reactors. • The first B-2 bomber was publicly displayed on Nov. 22, 1988, but its first flight was on July 17, 1989. • The combat effectiveness of the B-2 was proved in the Balkans, where it was responsible for destroying 33 percent of all Serbian targets in the first eight weeks. • In support of Operation Enduring Freedom, the B-2 flew one of its longest missions to date from Whiteman to Afghanistan and back. • The B-2 completed its first-ever combat deployment in Iraq, flying 22 sorties and releasing more than 1.5 million pounds of munitions. Fordo facility Location and structure: Fordo is 30 kilometers northeast of Qom, embedded within a mountain at an altitude of approximately 1,750 m, with over 80 meters of rock and volcanic shielding — making it one of Iran's most fortified sites. Technical role: It houses two underground halls that can hold about 3,000 IR-1 centrifuges, enriching uranium up to 60 percent — a level nearing weapons -grade. Strategic importance: It is a primary target in any military effort to prevent Iran from achieving nuclear military capability, due to its high capacity and protection. Natanz reactor Location and structure: Situated near Kashan in central Iran, partially buried under about 8 meters of earth with a 220meter-thick concrete roof, naturally shielded by surrounding mountainous terrain. Technical role: Contains primary and experimental plants with over 14,000 centrifuges (IR-1, IR-2m, IR-4, IR-6), making it Iran's main industrial enrichment hub. Strategic importance: Responsible for producing most of Iran's low-enriched uranium and plays a key role in centrifuge development. Isfahan nuclear complex Location and structure: Located south of Isfahan on an arid plateau away from populated areas, it is neither buried nor heavily fortified. Technical role: Includes a Uranium Conversion Facility (UCF); a research reactor fuel production plant; and a metallic fuel pelletizing plant, and three research reactors. Strategic importance: Serves as the backbone of Iran's nuclear research and production infrastructure, supplying both Natanz and Fordo. The Pentagon used some of the world's most advanced aircraft for Saturday's strikes. The B-2 Spirit is a multi-role bomber capable of delivering both conventional and nuclear munitions. The bomber represents a major milestone in the US bomber modernization program. The B-2 brings massive firepower to bear anywhere on the globe through seemingly impenetrable defenses. According to US officials, the bombers that carried out the Iran strikes flew for nearly 37 hours non-stop from its Missouri base, refueling in mid-air multiple times before striking in the early hours of Sunday. A B-2 bomber offers several key advantages, primarily due to its stealth capabilities and global reach. • A range over 11,000 km without refueling, capable of global reach from distant American bases. • Stealth abilities such as flying-wing design and radar-absorbing materials that allow it to evade air defenses. • It can carry both nuclear and conventional weapons, including the GBU‑57 bunker-buster bomb. Initial reports quoted by Asharq News indicated that Fordo was hit with the GBU‑57, the most powerful US conventional bunker buster, designed for deeply buried targets like Fordo, which lies 90 meters underground. Fox News reported six bunker-busting bombs were dropped on Fordo, alongside approximately 30 Tomahawk cruise missiles fired at Natanz and Isfahan. The GBU‑57 'Massive Ordnance Penetrator' was designed by American military engineers to devastate deeply buried bunkers without radioactive fallout. It was the only nonnuclear weapon that could reach Iran's hardest target. • Weight: ~13,600 kg • Length: 6.2 meters. • Diameter: 0.8 meters. • Explosive payload: 2,400 kg of high explosives. • Guidance: GPS + inertial navigation. * Penetration: Up to 60 meters of reinforced concrete or dense rock. A Tomahawk cruise missile is a precision weapon that launches from ships, submarines and ground launchers and can strike targets precisely from a great distance, even in heavily defended airspace. • Range: 1,250–2,500 km depending on variant. • Speed: Subsonic (~880 km/h). • Guidance: Inertial navigation, GPS, with some variants using terminal guidance (TERCOM, DSMAC). • Warhead: ~450 kg conventional explosives. • Launch platforms: Ships and submarines. There has been a torrent of responses to the US move against Iran, Asharq News reported. President Trump declared the mission's success, stating that the Fordo facility was 'gone,' and Iran's primary nuclear enrichment sites 'completely and utterly destroyed.' Later on Sunday, US Defense Secretary Pete Hegseth said the strikes were an incredible and overwhelming success that have 'obliterated Tehran's nuclear ambitions.' For its part, Iran's Tasnim News Agency quoted an official saying the nuclear sites had been evacuated in advance, and the damage was 'not irreparable.' The Atomic Energy Organization of Iran stated there was 'no risk of any radiation leak.' Iran emphasized its nuclear industry would not be halted.

Saudi Crown Prince Discusses Region's Tensions with GCC, French, Italian Leaders

Saudi Arabia's Crown Prince Mohammed bin Salman discussed the escalating tensions in the region following the US attacks with GCC leaders through a series of phone calls on Sunday, according to the Saudi Press Agency. Series of Phone Calls On Sunday, Saudi Arabia expressed its deep concern over the recent strikes and urged restraint to avoid more escalation, the Saudi Foreign Ministry said in a statement. The Crown Prince held separate telephone calls with several Gulf Cooperation Council leaders including King Hamad bin Isa Al-Khalifa of Bahrain, Sultan Haitham bin Tariq of Oman, Emir of Qatar Sheikh Tamim bin Hamad Al-Thani as well as Emir of Kuwait Sheikh Meshal Al-Sabah. Furthermore, the prince received a phone call from UAE President Sheikh Mohammed bin Zayed Al-Nahyan. During the calls, the leaders discussed the latest regional developments, such as Israel's ongoing attacks on Iran and the US strikes on Iranian nuclear facilities earlier on Sunday. They stressed the unity and solidarity of GCC member states and emphasized the significance of collective efforts to exercise restraint, avoid further escalation, and seek diplomatic solutions to the conflict. On Sunday, Prince Mohammed also received a phone call from French President Emmanuel Macron and Prime Minister of Italy Giorgia Meloni. The calls focused on the latest developments in the Middle East and the consequences of the escalation of tensions in the region following the US strikes. US Strikes on Iran The US launched airstrikes on Sunday against Iran's nuclear facilities in Natanz, Fordow, and Isfahan. 'The United States showed that they have no respect to United Nations Charter. They have no respect to international law. They crossed a very big red line by attacking nuclear facilities,' Iranian Foreign Minister Abbas Araghchi said. Moreover, Araghchi accused Trump of not only betraying Iran by abusing its commitment to diplomacy but also deceiving his own voters by implementing the wishes of a war criminal. 'He has betrayed not only Iran by abusing our commitment to diplomacy but also deceived his own voters by submitting to the wishes of a wanted war criminal who has grown accustomed to exploiting the lives and wealth of American citizens to further the Israeli regime's objectives,' he added. Israel-Iran War On June 13, Israel launched a wave of airstrikes on Iran under the name of Operation Rising Lion. The military campaign targeted Iran's nuclear facilities and killed top military commanders and nuclear scientists. As a response, Iran launched a retaliatory wave of missiles against Israel and targeted Tel Aviv. Israel also killed three more Iranian nuclear scientists, bringing the total number of scientists slain to nine, Gulf News reported. Currently, both countries are trading missiles and attacks amid intensifying efforts to halt the conflict.

NATO strikes spending deal, but Spain exemption claim risks Trump ire

BRUSSELS, Belgium: NATO on Sunday signed off on a pledge to ramp up defense spending before its upcoming summit, but Madrid insisted it would not need to hit the five percent of GDP demanded by US President Donald Trump. The claim by Spanish Prime Minister Pedro Sanchez sets up a potential clash with Trump, who has pressured allies to commit to that headline figure when they meet for the two-day gathering starting on Tuesday in The Hague. Spain had been the last holdout on a compromise deal that sees allies promise to reach 3.5 percent on core military needs over the next decade, and spend 1.5 percent on a looser category of 'defense-related' expenditures such as infrastructure and cybersecurity. Multiple diplomats at NATO said the agreement — set to be unveiled at the summit — had gone through with the approval of all 32 nations and that there was no exemption for Madrid. But within minutes Sanchez came out saying he had struck an accord with NATO that would see his country keep respecting its commitments 'without having to raise our defense spending to five percent of gross domestic product.' 'We understand the difficulty of the geopolitical context, fully respect the legitimate desire of other countries to increase their defense investment, if they so wish, but we are not going to do it,' he said. NATO diplomats now fear that Spain's position could undermine its carefully choreographed show of unity with Trump in The Hague, which already risks being overshadowed by the US decision to strike Iran. 'Not ok,' one diplomat said, on condition of anonymity. Madrid's claims came after Sanchez on Thursday threw a last-minute grenade into preparations for the gathering in the Netherlands by taking a strong stand against the agreement. In a blistering letter to NATO chief Mark Rutte, Sanchez said that committing to a headline figure of five percent of GDP 'would not only be unreasonable, but also counterproductive.' That prompted a warning from Trump that 'Spain has to pay what everybody else has to pay.' 'NATO is going to have to deal with Spain,' he told reporters on Friday, calling the country 'notorious' for spending less on defense than other alliance members. The outburst from Madrid's center-left leader also sparked fury from other NATO members desperate to keep Trump — who has threatened not to protect allies spending too little — on their side. The pledge is seen as key both to satisfying Trump and helping NATO build up the forces it needs to deter Russia. After several days of wrangling involving Sanchez and Rutte, officials said Spain on Sunday signed off on the pledge. Diplomats said that language around the spending pledge in the summit's final declaration had been slightly softened from 'we commit,' to 'allies commit.' They insisted the fundamentals of the deal remained intact and that it applied to Spain. But government sources in Madrid said the linguistic tweak meant only those countries that opted-in were covered by the promise and that Rutte was set to send a letter to Sanchez saying that Spain will have 'flexibility.' Sanchez is facing a difficult balancing act of aligning with NATO allies and cajoling his junior coalition partner, the far-left alliance Sumar, which is hostile to increasing military spending. Spain has been one of the lowest-spending NATO countries on defense in relative terms. The country is only set to hit the alliance's current target of two percent this year after a 10-billion-euro ($11.5 billion) injection.
