What to know about Iran's nuclear sites
DUBAI, United Arab Emirates (AP) — Israel attacked multiple Iranian nuclear and military sites on Friday as tensions reached new heights over Tehran's rapidly advancing nuclear program.
Israeli leaders said the attack was necessary to head off what they claimed was an imminent threat that Iran would build nuclear bombs. Iran long has insisted its program is peaceful and U.S. intelligence agencies have assessed that Tehran was not actively pursuing the bomb.
The attack came one day after the International Atomic Energy Agency's Board of Governors censured Iran for the first time in 20 years for not working with its inspectors. Iran immediately announced it would establish a third enrichment site in the country and swap out some centrifuges for more-advanced ones.
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.
Here's a look at some major Iranian sites and their importance in Tehran's 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.
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.
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 sabotage 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 a facility as Natanz.
Buried under a mountain and protected by anti-aircraft batteries, Fordo appears designed to withstand airstrikes.
Its construction began at least in 2007, according to the International Atomic Energy Agency, 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.
Bushehr nuclear power plant
Iran's only commercial nuclear power plant is in Bushehr on the Persian Gulf, some 750 kilometers (465 miles) south of Tehran. Construction on the plant began under Iran's Shah Mohammad Reza Pahlavi in the mid-1970s. After the 1979 Islamic Revolution, the plant was repeatedly targeted in the Iran-Iraq war. Russia later completed construction of the facility.
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 United Nations' International Atomic Energy Agency.
Arak heavy water reactor
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. That would provide Iran another path to the bomb beyond enriched uranium, should it choose to pursue the weapon. Iran had agreed under its 2015 nuclear deal with world powers to redesign the facility to relieve proliferation concerns.
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.
Tehran Research Reactor
The Tehran Research Reactor is at the headquarters of the Atomic Energy Organization of Iran, the civilian body overseeing the country's atomic program. The U.S. actually provided Iran the reactor in 1967 as part of America's 'Atoms for Peace' program during the Cold War. It initially required highly enriched uranium but was later retrofitted to use low-enriched uranium over proliferation concerns.

Iran Retaliates and Israel Vows More Strikes After Devastating Attack
Iran was reeling and firing missiles and drones on Friday after Israel carried out its largest attack ever against Iran, waves of coordinated airstrikes that hit nuclear sites and killed much of the country's military chain of command along with several nuclear scientists. Israel's assault early Friday morning and Iran's response immediately raised the prospect of a wider conflict engulfing the Middle East, although Iran's military capabilities and its proxy militias have been weakened by 20 months of Israeli attacks. Prime Minister Benjamin Netanyahu of Israel described the assault as a last resort to prevent Iran from obtaining a nuclear weapon, which Israel calls an existential threat, and he vowed that the attacks would last 'as many days as it takes.' Iran's supreme leader, Ayatollah Ali Khamenei, said in a televised statement on Friday that Iran would act forcefully to punish Israel for the attack. 'Life will be dark for them,' he said, adding: 'They started it. They started a war.' Iran's foreign minister, Abbas Araghchi, told the United Nations Security Council on Friday that Israel's strikes had killed 78 people and injured 329 others. In response, Iran fired 'fewer than 100' missiles in two waves toward Israel on Friday, most of which were intercepted by Israel's robust air defenses, according to Brig. Gen. Effie Defrin, an Israeli military spokesman. But several buildings were hit, some with shrapnel. Want all of The Times? Subscribe.

Live Updates: Iranian Missiles Hit Multiple Sites in Tel Aviv, Injuring at Least 22
The Abqaiq oil processing plant in Saudi Arabia, after it was damaged in an attack from Iran in 2019. In September 2019, a barrage of drones and cruise missiles slammed into two Saudi oil facilities near the Persian Gulf, including one of the largest in the world, igniting small fires that briefly interrupted production. The projectiles were later traced to Iran, and despite its stringent denials, the desire to avoid a repeat of the incident prompted a new and sustained effort by Saudi Arabia and the other Arab Gulf States to use détente and diplomacy toward the Islamic Republic to de-escalate regional tensions. That effort is being put to the test as never before on Friday amid waves of Israeli attacks on Iran aimed at destroying key facilities and decapitating the military and civilian leadership running its nuclear programs. 'I think the tension is palpable and everybody is concerned about possible blowback,' said Firas Maksad, the managing director for the Middle East and North Africa at the Eurasia Group, a New York-based risk analysis organization. 'This is a moment of great uncertainty throughout the region. It is the big war the region has been both fearing and anticipating for years.' The Gulf Arab states, and indeed much of the Arab world, were quick to issue robust condemnations of the Israeli attacks like this one from Riyadh: 'The Kingdom of Saudi Arabia expresses its strong condemnation and denunciation of the blatant Israeli aggression against the brotherly Islamic Republic of Iran, which undermine its sovereignty and security and constitute a clear violation of international laws and norms.' The Saudi foreign minister, Prince Faisal bin Farhan, and several others from the region called their Iranian counterpart to repeat the condemnation. With the Arab world already inflamed by the Gaza conflict, a related war in Lebanon, a long-running civil war in Yemen and Syria barely staggering to its feet after 14 years of violence and civil war, there was also frustration that attempts at de-escalation had failed. It was tensions over Yemen that had prompted the 2019 attack against Saudi Arabia. 'We are frustrated and fatigued,' said Bader al-Saif, a professor of history at Kuwait University. 'The region has been doing its best for the past few years to come to terms with everyone, including Israel,' he added. 'But Israel is trying to reset the region to their own tune and they are trying to do this violently.' The United States was considered part of the problem. Although President Trump kept a certain distance from the prospect of conflict between the Middle East's two most powerful militaries, and had been trying to negotiate a new deal to defuse Iran's nuclear program, he had not blocked Prime Minister Benjamin Netanyahu of Israel from launching the attack. 'After the triumphant Trump visit to the Gulf and serious mediation efforts, there will also be some frustration that Trump has proved unwilling or unable to restrain Netanyahu,' said Dr. Sanam Vakil, the director of the Middle East and North Africa Programme at Chatham House, a London-based research institute. Part of the equation is that the region depends heavily on American military power for its defense, with U.S. forces deployed at air bases in Qatar, the United Arab Emirates and Saudi Arabia as well as a major naval base on Bahrain, along with troops scattered across Iraq and northeastern Syria. While the Gulf bases were established in recent decades not least as a deterrent for Iran, there was fear that Tehran might miscalculate by targeting them, widening the conflict by drawing in the United States. Gulf countries have all committed billions of dollars to major, futuristic development projects meant to wean their economies off oil, so a major war would also jeopardize those plans. The attacks by Israel against Iran immediately threatened the region's economy, with airlines canceling countless flights for the foreseeable future. Israel, Iran, Iraq and Jordan all closed their airspace. Countries like Jordan, Lebanon and Egypt that depend heavily on tourist dollars had been hoping for a revival. Jordan said it was shooting down Iranian projectiles that violated its airspace, but underscored that it was protecting itself and not joining the war. Syria was considered completely out of this conflict. Of course, Arab states had been worried about Iran's acquiring nuclear weapons as well, even if there was some sense that Israel had exaggerated the threat. Crippling the Iranian nuclear program would provoke some satisfaction, analysts said, but it seemed an enormous gamble. 'If Israel and or the United States can finish off the threat to the Gulf countries via military means, I don't think that Arab leaders will be shedding tears,' Mr. Maksad said. 'The great concern is a job half-done that then leaves them wide open to retaliation and undermines their national development projects in the process.' Two rounds of tit-for-tat attacks between Israel and Iran last year ended fairly quickly, but there was anxiety that this new one could escalate. That increased the potential for unforeseen consequences. 'For the Iranians, this will require a different kind of response, more sustained and more hurtful,' said Randa Slim, a senior fellow at the Middle East Institute in Washington. For the moment Iran's beleaguered proxy forces, including Hezbollah, did not react beyond verbal condemnations. Worst-case scenarios include the closure of the Strait of Hormuz, a choke point for Persian Gulf oil exports. Since Iran depends on that flow as well, even as it is limited at the moment due to sanctions, that is seen as a possible last desperate step. 'If this continues, we are going into unchartered terrain,' Dr. al-Saif said. Ismaeel Naar contributed reporting.
