What is the Strait of Hormuz? Why Iran has threatened to close it after US conflict
As Iran and Israel enter a ceasefire on June 24, the future of the conflict and U.S. involvement remains on unsteady ground, following Iran's retaliatory strike on an overseas U.S. military base one day prior.
Turmoil continues to roil the Middle East in a 12-day conflict that reached new heights June 21 after President Donald Trump authorized a series of U.S. missile strikes on three Iranian nuclear facilities. Ever since, world leaders, markets and Americans have speculated how Iran might respond, with the first action of retaliation seen on June 23 when Iran fired several missiles at the largest U.S. military base in the region just outside of Doha, Qatar.

While it is unclear if Iran's strikes on the Al Udeid Air Base marked the end of its response, the Islamic Republic still has another chess piece at its disposal should the conflict continue: the Strait of Hormuz.
The Strait of Hormuz is a major oil transportation route, ferrying around 20% of the world's oil and gas flow.
The narrow channel, whittling down to just 21 miles across at one point, connects the Persian Gulf to the Gulf of Oman and the wider Arabian Sea. The waterway's choke point is sandwiched by the Iranian coastline to one side and a small Omani peninsula on the other.

It is a vital route for exporting oil from major producers like Saudi Arabia, Iraq, Iran, Qatar, and the UAE.
The Strait of Hormuz is a vital artery for global energy flows, accounting for about 25% of global seaborne oil shipments and about 20% of liquified natural gas flows.
Iran has threatened to mine the strait in recent days to effectively block the transportation of oil, a disruption that would likely result in higher fuel costs for global consumers, including Americans, analysts told USA TODAY. If oil prices surge, the price of almost everything goes up as well.
Iran's parliament approved a measure the day after U.S. airstrikes hit three of its nuclear facilities, endorsing the closure of the Strait of Hormuz, making it a possible option for retaliation, though the decision to close the channel ultimately belongs to Iran's Supreme National Security Council.

IAEA chief says Iran could be enriching uranium within months
(Reuters) -Iran could be producing enriched uranium in a few months, the head of the U.N. nuclear watchdog Rafael Grossi was quoted as saying on Sunday, raising doubts about how effective U.S. strikes to destroy Tehran's nuclear programme have been. U.S. officials have stated that their strikes obliterated key nuclear sites in Iran, although U.S. President Donald Trump said on Friday he would consider bombing Iran again if Tehran is enriching uranium to worrisome levels. "The capacities they have are there. They can have, you know, in a matter of months, I would say, a few cascades of centrifuges spinning and producing enriched uranium, or less than that," Grossi told CBS News in an interview. "Frankly speaking, one cannot claim that everything has disappeared and there is nothing there," he added, according to the transcript of an interview on "Face the Nation" with Margaret Brennan due to air on Sunday. Saying it wanted to remove any chance of Tehran developing nuclear weapons, Israel launched attacks on Iran earlier this month, igniting a 12-day air war that the U.S. eventually joined. Iran says its nuclear programme is for peaceful purposes only. Grossi, who heads the Vienna-based International Atomic Energy Agency, said the strikes on sites in Fordow, Natanz and Isfahan had significantly set back Iran's ability to convert and enrich uranium. However, Western powers stress that Iran's nuclear advances provide it with an irreversible knowledge gain, suggesting that while losing experts or facilities may slow progress, the advances are permanent. "Iran is a very sophisticated country in terms of nuclear technology," Grossi said. "So you cannot disinvent this. You cannot undo the knowledge that you have or the capacities that you have." Grossi was also asked about reports of Iran moving its stock of highly enriched uranium in the run-up to the U.S. strikes and said it was not clear where that material was. "So some could have been destroyed as part of the attack, but some could have been moved," he said.

Iran could resume uranium enrichment within months: IAEA chief
Iran may be able to restart uranium enrichment in a matter of months despite a wave of attacks by the United States and Israel that targeted its nuclear infrastructure, according to the head of the United Nations nuclear watchdog, Rafael Grossi. The remarks came on Saturday, days after US President Donald Trump insisted this month's attacks had set Iran's nuclear ambitions back 'by decades'. Speaking to CBS News on Saturday, the director-general of the International Atomic Energy Agency (IAEA) said while key facilities had been hit, some are 'still standing'. 'They can have, you know, in a matter of months, I would say, a few cascades of centrifuges spinning and producing enriched uranium,' Grossi said, adding that it could even be sooner. He raised concerns over Iran's stockpile of 60 percent enriched uranium, just below weapons grade, which could theoretically produce more than nine nuclear bombs if refined further. He acknowledged the IAEA does not know whether this stockpile was moved before the bombings or partially destroyed. 'There has to be, at some point, a clarification,' he said. The Israeli assault began on June 13 with strikes on Iran's nuclear and military sites. Israel claimed the attacks were designed to prevent Iran from building a nuclear weapon, an accusation Tehran has consistently denied. The US joined the offensive days later, hitting three of Iran's nuclear facilities. In the wake of the attacks, Iranian lawmakers moved to suspend cooperation with the IAEA and denied Grossi's request to inspect facilities, including the underground enrichment plant at Fordow. 'We need to be in a position to confirm what is there, where it is, and what happened,' Grossi said. The Iranian Ministry of Health reported at least 627 civilian deaths across the country during the 12-day assault that also saw 28 people killed in Israel in retaliatory strikes launched by Iran, according to Israeli authorities. On Saturday, Iran's judiciary said an Israeli missile strike on Tehran's Evin Prison on June 23 killed 71 people, including military recruits, detainees and visitors. Reporting from Tehran, Al Jazeera's Resul Serdar Atas said on Sunday that Iranians believe Israel struck the facility to free the prisoners. 'Definitely the worst way to do that is to bomb the facility itself and kill civilians,' he added. 'This prison is not dedicated to specific crimes. We see political prisoners, journalists, financial offenders, and foreign detainees. 'In 2018, the United States put Evin Prison on its sanctions list, and the European Union did the same in 2021 because of human rights violations.'

Analysis-U.S. strikes on Iran's nuclear sites set up "cat-and-mouse" hunt for missing uranium
By Francois Murphy and John Irish VIENNA (Reuters) -The U.S. and Israeli bombing of Iranian nuclear sites creates a conundrum for U.N. inspectors in Iran: how can you tell if enriched uranium stocks, some of them near weapons grade, were buried beneath the rubble or had been secretly hidden away? Following last weekend's attacks on three of Iran's top nuclear sites - at Fordow, Natanz and Isfahan - President Donald Trump said the facilities had been "obliterated" by U.S. munitions, including bunker-busting bombs. But the U.N. nuclear watchdog, the International Atomic Energy Agency, which monitors Tehran's nuclear program, has said it's unclear exactly what damage was sustained at Fordow, a plant buried deep inside a mountain that produced the bulk of Iran's most highly enriched uranium. IAEA chief Rafael Grossi said on Monday it was highly likely the sensitive centrifuges used to enrich uranium inside Fordow were badly damaged. It's far less clear whether Iran's 9 tonnes of enriched uranium - more than 400 kg of it enriched to close to weapons grade - were destroyed. Western governments are scrambling to determine what's become of it. Reuters spoke to more than a dozen current and former officials involved in efforts to contain Iran's nuclear program who said the bombing may have provided the perfect cover for Iran to make its uranium stockpiles disappear and any IAEA investigation would likely be lengthy and arduous. Olli Heinonen, previously the IAEA's top inspector from 2005 to 2010, said the search will probably involve complicated recovery of materials from damaged buildings as well as forensics and environmental sampling, which take a long time. "There could be materials which are inaccessible, distributed under the rubble or lost during the bombing," said Heinonen, who dealt extensively with Iran while at the IAEA and now works at the Stimson Center think-tank in Washington. Iran's more than 400 kg of uranium enriched to up to 60% purity - a short step from the roughly 90% of weapons grade - are enough, if enriched further, for nine nuclear weapons, according to an IAEA yardstick. Even a fraction of that left unaccounted for would be a grave concern for Western powers that believe Iran is at least keeping the option of nuclear weapons open. There are indications Iran may have moved some of its enriched uranium before it could be struck. IAEA chief Grossi said Iran informed him on June 13, the day of Israel's first attacks, that it was taking measures to protect its nuclear equipment and materials. While it did not elaborate, he said that suggests it was moved. A Western diplomat involved in the dossier, who asked not to be identified because of the sensitivity of the issue, said most of the enriched uranium at Fordow would appear to have been moved days in advance of the attacks, "almost as if they knew it was coming". Some experts have said a line of vehicles including trucks visible on satellite imagery outside Fordow before it was hit suggests enriched uranium there was moved elsewhere, though U.S. Defense Secretary Pete Hegseth on Thursday said he was unaware of any intelligence suggesting Iran had moved it. Trump has also dismissed such concerns. In an interview due to air on Sunday with Fox News Channel's "Sunday Morning Futures", he insisted the Iranians "didn't move anything." "It's very dangerous to do. It is very heavy - very, very heavy. It's a very hard thing to do," Trump said. "Plus we didn't give much notice because they didn't know we were coming until just, you know, then." The White House did not respond to a request for comment. The State Department referred Reuters to Trump's public remarks. A second Western diplomat said it would be a major challenge to verify the condition of the uranium stockpile, citing a long list of past disputes between the IAEA and Tehran, including Iran's failure to credibly explain uranium traces found at undeclared sites. "It'll be a game of cat and mouse." Iran says it has fulfilled all its obligations towards the watchdog. PICTURE BLURRED Before Israel launched its 12-day military campaign aimed at destroying Iran's nuclear and missile capabilities, the IAEA had regular access to Iran's enrichment sites and monitored what was inside them around the clock as part of the 191-nation Non-Proliferation Treaty aimed at preventing the spread of nuclear weapons, to which Iran is a party. Now, rubble and ash blur the picture. What's more, Iran has threatened to stop working with the IAEA. Furious at the non-proliferation regime's failure to protect it from strikes many countries see as unlawful, Iran's parliament voted on Wednesday to suspend cooperation. Tehran says a resolution this month passed by the IAEA's 35-nation Board of Governors declaring Iran in breach of its non-proliferation obligations paved the way for Israel's attacks, which began the next day, by providing an element of diplomatic cover. The IAEA denies that. Iran has repeatedly denied that it has an active program to develop a nuclear bomb. And U.S. intelligence - dismissed by Trump before the airstrikes - had said there was no evidence Tehran was taking steps toward developing one. However, experts say there is no reason for enriching uranium to 60% for a civilian nuclear program, which can run on less than 5% enrichment. As a party to the NPT, Iran must account for its stock of enriched uranium. The IAEA then has to verify Iran's account by means including inspections, but its powers are limited - it inspects Iran's declared nuclear facilities but cannot carry out snap inspections at undeclared locations. Iran has an unknown number of extra centrifuges stored at locations the U.N. nuclear watchdog is unaware of, the IAEA has said, with which it might be able to set up a new or secret enrichment site. That makes hunting down the material that can be enriched further, particularly that closest to bomb grade, all the more important. "Iran's stockpile of 60% enriched uranium may not have been part of the 'mission' but it is a significant part of the proliferation risk - particularly if centrifuges are unaccounted for," Kelsey Davenport of the Washington-based Arms Control Association said on X on Friday. The IAEA can and does receive intelligence from member states, which include the United States and Israel, but says it takes nothing at face value and independently verifies tip-offs. Having pummelled the sites housing the uranium, Israel and the U.S. are seen as the countries most likely to accuse Iran of hiding it or restarting enrichment, officials say. Israeli Prime Minister Benjamin Netanyahu's office did not respond to a request for comment for this story. CHASING SHADOWS U.N. inspectors' futile hunt for large caches of weapons of mass destruction in Iraq, which preceded the U.S.-led invasion in 2003, showed the enormous difficulty of verifying foreign powers' assertions about hidden stockpiles of material when there is little tangible information to go on. As in Iraq, inspectors could end up chasing shadows. "If the Iranians come clean with the 400 kg of HEU (highly enriched uranium) then the problem is manageable, but if they don't then nobody will ever be sure what happened to it," a third Western diplomat said. The IAEA, which answers to 180 member states, has said it cannot guarantee Iran's nuclear development is entirely peaceful, but has no credible indications of a coordinated weapons program. The U.S. this week backed the IAEA's verification and monitoring work and urged Tehran to ensure its inspectors in the country are safe. It is a long journey from there to accounting for every gram of enriched uranium, the IAEA's standard. The above-ground plant at Natanz, the smaller of the two facilities enriching uranium up to 60 percent, was flattened in the strikes, the IAEA said, suggesting a small portion of Iran's enriched uranium stockpile may have been destroyed. Fordow, Iran's most deeply buried enrichment plant, which was producing the bulk of 60%-enriched uranium, was first seriously hit last weekend when the United States dropped its biggest conventional bombs on it. The damage to its underground halls is unclear. An underground area in Isfahan where much of Iran's most highly enriched uranium was stored was also bombed, causing damage to the tunnel entrances leading to it. The agency has not been able to carry out inspections since Israel's bombing campaign began, leaving the outside world with more questions than answers. Grossi said on Wednesday the conditions at the bombed sites would make it difficult for IAEA inspectors to work there - suggesting it could take time. "There is rubble, there could be unexploded ordnance," he said. Heinonen, the former chief IAEA inspector, said it was vital the agency be transparent in real time about what its inspectors have been able to verify independently, including any uncertainties, and what remained unknown. "Member states can then make their own risk assessments," he said.
