Tanker reports explosions nearby off Yemen, crew safe - UKMTO

The system produced another striking result this weekend, when Iran’s five-member team won five gold medals at the International Olympiad on Astronomy and Astrophysics in Hanoi, securing the world championship for a third consecutive year.

The achievement is part of a much longer record. Iran has spent decades identifying exceptional schoolchildren, training them intensively and directing them toward mathematics, physics, engineering, computer science and other technical disciplines.

International victories bring prestige, but the students themselves are arguably more valuable. They form part of the human capital on which Iran’s universities, technology sector and some of its most strategically important industries depend.

That is also where the system encounters its central contradiction. Iran has proved remarkably effective at finding and developing scientific talent. It has had considerably more difficulty keeping it.

A pipeline for elite science

Iran’s Olympiad program is not simply a collection of international competitions. It is the upper end of an extensive system for identifying gifted students while they are still in school.

The Young Scholars Club organizes national Olympiads across mathematics, physics, chemistry, biology, informatics, astronomy and other disciplines, with many successful competitors coming through Iran’s selective schools for gifted students, commonly known as Tizhooshan.

Students who advance through successive rounds receive specialized instruction well beyond the standard school curriculum. A small number are eventually selected for international teams and spend months preparing to compete against the strongest students from other countries.

Participation has grown sharply. Some 121,000 students entered Iran’s scientific Olympiads in the Iranian year ending in March 2026, up from 87,000 the previous year, an increase of about 40% and the highest participation in a decade.

There are substantial incentives for those who reach the top. International gold medalists in established scientific Olympiads can receive exemptions from Iran’s fiercely competitive national university entrance examination, or Konkoor, giving them a privileged route into the country’s leading universities and technical programs.

The results extend well beyond astronomy. Iran has repeatedly won medals in mathematics, physics, chemistry, biology and informatics, including some of the highest placements in international competition.

For the state, those performances provide visible evidence that sanctions and international isolation have not prevented Iran from cultivating world-class scientific ability.

There is substance to that claim. Repeated success shows that Iran has developed an effective mechanism for discovering exceptional students and preparing them to compete at the highest level.

But Olympiad results demonstrate concentrated excellence rather than the overall strength of Iran’s education system. A small group of highly selected students can receive intensive training and state support while ordinary schools face shortages, unequal resources and deteriorating economic conditions.

More revealing is what happens to the medalists after they leave school.

From Olympiad medals to strategic universities

Research into the careers of International Mathematical Olympiad medalists illustrates how concentrated Iran’s elite science pipeline has become.

Among 75 Iranian mathematics medalists whose undergraduate education could be established in one study covering medalists from 1986 to 2005, 71 attended Sharif University of Technology and the other four went to the University of Tehran.

The concentration provides a direct link between Iran’s Olympiad system and two of the institutions at the center of its scientific establishment.

Sharif is widely regarded as Iran’s leading engineering and technical university. It has also had longstanding connections with research areas tied to Iran’s nuclear, missile and defense sectors.

Several research bodies located at the university have been sanctioned by the United States under authorities targeting proliferation of weapons of mass destruction.

European sanctions have gone further, citing Sharif’s cooperation with organizations involved in Iran’s ballistic missile program and its connections with entities associated with nuclear research and uranium enrichment.

The University of Tehran has its own history of research touching sensitive fields. Its academics have worked in areas relevant to missiles, drones, aerospace technology and nuclear science, as well as projects connected to Iran’s space program.

The university also played an early role in the development of Iran’s nuclear infrastructure. Its Atomic Center, established in the 1960s around a US-supplied research reactor, was transferred to the Atomic Energy Organization of Iran in 1974 and became the Tehran Nuclear Research Center.

None of this means Olympiad winners are systematically recruited into nuclear or missile programs. There is no evidence of such a direct mechanism, and the overwhelming majority of teaching and research at Iran’s major universities is civilian.

The connection is one of human capital.

The mathematics, physics, computing and problem-solving skills cultivated through Olympiad training are also essential to artificial intelligence, aerospace engineering, advanced computing, cybersecurity, nuclear science and missile development.

The universities that attract Iran’s strongest students supply engineers and researchers to a broad range of institutions, from civilian technology firms and research centers to parts of the defense and nuclear establishment.

For a heavily sanctioned state, such expertise has particular value.

Restrictions on imports, technology transfers, investment and international research collaboration make indigenous scientific capacity more important. Iran may struggle to obtain certain foreign technologies or advanced equipment, but scientific expertise developed domestically is considerably harder to restrict.

The Olympiad system therefore serves a purpose beyond medals. It identifies unusually capable students early, concentrates resources on their development and helps direct them toward disciplines important both to Iran’s economy and to sectors the state considers strategically vital.

But producing that talent does not mean Iran gets to keep it.

The talent drain

Studies of Iranian Olympiad medalists suggest that a substantial proportion eventually build their lives elsewhere.

Among 82 Iranian International Mathematical Olympiad medalists whose current location could be established in one study, 49 — around 60% — were living abroad.

The same research found a strong relationship between studying abroad and permanent migration. More than 70% of Olympiad medalists who pursued either undergraduate or doctoral education overseas eventually remained abroad, while those educated entirely in their home countries were considerably more likely to stay.

Other figures circulated in Iran have been even more dramatic.

In 2022, the secretary-general of the Iranian Talent Association said that 82 or 83 members of a group of 86 Olympiad medalists tracked by the organization had emigrated, arguing that inadequate support for talented young people inside Iran was a major factor.

Iranian officials disputed that figure and cited research suggesting that a majority of a much larger group of international Olympiad winners still lived in Iran or had returned after studying abroad.

The samples and methodologies differ, making the figures difficult to compare directly. But the broader problem of migration among Iran’s most highly educated young people is widely acknowledged.

For students who spend years preparing to compete at international level, the contrast between opportunities inside and outside Iran can be stark.

At home they face inflation, currency depreciation, weakened salaries, limited research funding, shortages of modern laboratory equipment, bureaucratic restrictions and obstacles to international scientific cooperation.

Sanctions deepen many of those pressures by limiting access to equipment, software, financing and research partnerships.

The qualities that make these students valuable to Iran also make them unusually mobile.

An international Olympiad medal is a credential recognized by universities around the world. A student emerging from Sharif with an Olympiad background can compete for places at elite graduate schools, research laboratories and technology companies abroad.

The investment that makes the student valuable inside Iran therefore also increases their ability to leave it.

Maryam Mirzakhani remains the best-known example.

She won mathematics Olympiad gold medals for Iran as a teenager, studied at Sharif and later moved to the United States, where she became a professor at Stanford University and the first woman to win the Fields Medal.

Her career demonstrated both sides of Iran’s Olympiad system: its ability to identify exceptional talent and its difficulty retaining the long-term scientific benefits of that talent.

That does not mean every medalist leaves. Many remain in Iran and contribute to universities, research centers, technology companies and industry. Some who study overseas also maintain scientific ties with Iran or eventually return.

But the loss carries disproportionate weight when those leaving represent some of the most intensively selected and trained scientific talent the country produces.

The Olympiad paradox

Iran’s investment in scientific Olympiads therefore remains rational even when some of its most successful products emigrate.

The system discovers talent that might otherwise go unnoticed, raises scientific standards, gives exceptional students opportunities and produces genuine international achievements.

It also develops scientists and engineers in disciplines Iran considers essential to its economic and technological future.

Under sanctions, that logic becomes even stronger. When technology, equipment and capital are difficult to import, investing in people becomes one of the few capabilities a country can develop largely from within.

Yet that strategy depends on more than discovering talented teenagers.

Iran can identify an exceptional student at 15, provide intensive training, waive the university entrance examination, send them to Sharif and celebrate when they defeat competitors from dozens of countries.

What the Olympiad system cannot provide is the research environment, professional freedom, economic security and long-term career prospects that determine where that student chooses to live at 25 or 35.

That gap can turn Iran’s investment into an unintended subsidy for institutions abroad.

Iranian families, schools and public institutions bear much of the cost of discovering and developing globally competitive students. Foreign universities, laboratories and companies can later recruit scientists and engineers whose foundational training has already been completed.

For Iran, the implications extend beyond academia. The same talent that can strengthen a university laboratory or technology company can also contribute to aerospace, artificial intelligence, nuclear research and other strategically important sectors.

This weekend’s five astronomy gold medals show that the first part of Iran’s system continues to work exceptionally well. For a third consecutive year, Iranian students have demonstrated that they can compete with the best young scientific talent in the world.

The harder measure of success comes years later: whether Iran can offer those students a future compelling enough to keep the talent it worked so hard to discover.

Iran reviews US response

Iran’s seven-day proposal, outlined by Foreign Minister Abbas Araghchi in New York, was sent to Washington through intermediaries and the United States subsequently provided its views on the plan, Deputy Foreign Minister Kazem Gharibabadi said Sunday.

“The proposal that Mr. Araghchi outlined in New York, Iran’s seven-day plan, was sent to the United States through intermediaries, and they provided their views on the plan,” Gharibabadi said.

  Iranian press sees diplomacy alive but narrowing after US response

The US response is being reviewed inside Iran and Tehran will communicate its final position through the appropriate channel once that process is complete, Gharibabadi said. Iran was also maintaining readiness for “other scenarios,” he added.

Parliament deputy speaker Hamid-Reza Haji Babaei separately said negotiations with Washington were taking place, while expressing little confidence that they would ultimately produce an understanding.

“Negotiations with the United States are in fact underway now,” Haji Babaei said.

Alaeddin Boroujerdi, a member of parliament’s National Security and Foreign Policy Committee, said US proposals had recently been conveyed through Qatar, although he did not know their details.

Foreign Ministry spokesman Esmaeil Baghaei said US proposals remained focused on the nuclear issue and Iran had already responded. He also rejected President Donald Trump’s remark that Washington did not know who represented Iran in negotiations, saying a six-member committee under the Supreme National Security Council was overseeing the process.

Lawmakers differ on further talks

Despite the exchanges, parliament’s National Security and Foreign Policy Committee spokesman Hassan Ghashghavi said there were no unresolved substantive issues requiring new negotiations.

“We are, in my view, at a post-negotiations stage both on the Strait of Hormuz and on the conditions,” Ghashghavi said.

Another committee member, Ebrahim Rezaei, said Iran would not retreat from its conditions and presented diplomacy and military pressure as the alternatives facing Washington.

“The Americans must either surrender to our diplomats or surrender to Iran’s missiles. We have no other proposal for them,” Rezaei said.

Nuclear debate continues as rial falls

The nuclear program remained part of the diplomatic debate. Baghaei said Iran remained bound by its obligations under the Treaty on the Non-Proliferation of Nuclear Weapons for as long as it remained a member.

Parliament will consider a possible withdrawal from the NPT while maintaining uranium enrichment, parliament board member Alireza Salimi said.

  US ‘feedback’ leaves Iran debating the price of diplomacy

Iran is also considering a Russian offer to take custody of its uranium enriched to 60%, with a final decision to be based on its national interests, Baghaei said.

The diplomatic maneuvering coincided with further pressure on Iran’s currency, with the US dollar rising above 2.7 million rials on the free market on Sunday.

The statements put the focus on Tehran’s review of Washington’s response, with Iranian officials differing over whether the next step requires further negotiations or a decision on proposals already exchanged.

The dollar traded at 2.723 million rials on the open market earlier on October 4, up 1.3% from the previous day.

The euro climbed above 3.06 million rials and the British pound surpassed 3.59 million rials.

US pressure targets oil revenue

Washington has sought in recent weeks to restrict the Iranian government's financial lifelines through a naval blockade, efforts to prevent Iranian oil exports and measures targeting channels used to move oil revenue.

  Iran’s rial hits another record low under economic and military pressure

US Treasury Secretary Scott Bessent said on October 3 that Iran would have no oil cargoes on the water this week and would earn no revenue from such shipments, describing it as a first.

Bessent described the US military campaign, naval blockade and economic isolation of the Islamic Republic as interconnected elements of Washington’s strategy.

Iranian parliament deputy speaker Ali Nikzad had earlier said the United States would “never” be able to reduce Iran’s oil exports to zero.

Government moves to curb currency slide

Iranian authorities are seeking ways to contain the currency’s decline and inflation as economic pressure increases.

Tasnim news agency, which is affiliated with the Revolutionary Guards, reported on Sunday that five Iranian banks were selling up to $10,000 to each person over 18 at a rate of 2.57 million rials per dollar on the second day of an official foreign currency program.

The banks participating in the program are Mellat, Tejarat, Melli, Saderat and Saman, according to Tasnim.

Lawmaker Mehdi Kouchakzadeh criticized the central bank program during an online parliamentary session on Sunday, questioning why it had been introduced at what he described as a time of severe foreign currency shortages.

“Other than their friends, dealers and thieves, who can afford to buy this $10,000?” Kouchakzadeh said. “This is money for butterfly skin patients and struggling people that is going into the pockets of capitalists and thieves.”

Kouchakzadeh called the policy a “crime” and urged parliament speaker Mohammad Bagher Ghalibaf to prevent its implementation.

The physical management of foreign currency was of “fundamental importance,” Ghalibaf said in response, promising to pursue the issue.

  As the rial sinks, Iranians seek shelter in almost anything else

Supreme National Security Council Secretary Mohsen Rezaei attended a meeting of the government’s economic coordination headquarters on October 3 and said the country was going through one of its most difficult periods.

Despite the deepening economic crisis and growing pressure on citizens, the Islamic Republic continues to pursue policies that have fueled confrontation, particularly its standoff with the United States and its nuclear program.

“We have a decision that I’ll make about Iran,” Trump told reporters. “Iran has been decimated, so the only question is it’ll either be the easy way or the hard way.”

Trump also said Iran was “virtually giving up” any plans to obtain a nuclear weapon, while reiterating that Tehran would never be allowed to acquire one.

Defense Secretary Pete Hegseth gave a clearer indication of what the harder option could involve, saying the Pentagon was working to ensure Trump retained “all the options he needs on the table” if Iran refused to abandon its nuclear ambitions.

“Iran will never, ever, ever have a nuclear weapon,” Hegseth said, describing Trump as “hell-bent and determined” to prevent it.

Pentagon preserves military options

Hegseth declined to say whether the USS Theodore Roosevelt carrier strike group, dispatched from San Diego last week, would be sent to the Middle East, saying his job was to give Trump the widest possible “decision space.”

He said Iran was trying to rebuild missile and other military capabilities damaged by US strikes but argued that damage to its defense industry had slowed that effort.

The military pressure has remained concentrated around the Strait of Hormuz, where Hegseth claimed Washington, rather than Tehran, now controlled the waterway. He described the US blockade as “ironclad” and said traffic was moving back toward pre-war levels.

Commercial vessels, however, continue to face attacks.

Iranian state media reported Saturday that another oil tanker had been hit in the strait. The IRGC-affiliated Fars News identified the vessel as the Ore Vinst and claimed it had been traveling under US escort when it was targeted while heading toward Oman.

The United States has not reacted to the claim yet.

The incident followed a series of attacks on ships transiting Hormuz even as Washington has escorted vessels through the waterway and sought to restore energy flows.

US says pressure campaign is cutting Iran’s revenue

The blockade is also intended to deny Tehran the oil income Washington says it needs to rebuild its military capabilities.

Treasury Secretary Scott Bessent said Iran would have no oil shipments at sea this week and therefore no revenue from those cargoes, describing the blockade and subsequent economic isolation as the next stages of a campaign that began with US military strikes.

“We had kinetic [action], we destroyed their navy, their air force, substantially depleted their drone and missile capability,” Bessent said.

“Then we went to what the president calls the Iron Wall and the blockade,” he added. “And now we have Operation Economic Outcast and we are isolating them economically like it’s never happened before.”

White House Communications Director Steven Cheung also said Iranian oil exports had been “stopped completely” and cited a Bloomberg report putting inflation at almost 90%.

Iran’s government has acknowledged increasing economic pressure while rejecting Washington’s claim that its strategy is succeeding.

President Masoud Pezeshkian said Saturday his government had adopted a “new posture” to manage what he described as exceptional conditions.

“The enemy’s plan in recent months has been to cut the country’s vital arteries with the aim of putting pressure on the Iranian people,” he wrote on X.

Pezeshkian said the pressure had increased but argued that government measures and public cooperation had prevented Iran’s adversaries from achieving their objectives.

Diplomatic channel remains open

Trump’s pending decision comes with diplomacy still technically alive but with no clear sign of a breakthrough after the latest contacts between Washington and Tehran.

The conservative Sobh-e No newspaper which is close to Iran’s chief negotiator Mohammad Bagher Ghalibaf reported Saturday that Iran was reviewing a US proposal conveyed through Qatar setting out a roadmap and timetable for further negotiations.

The paper said Tehran continued to demand that Washington first meet its commitments, including sanctions relief and the release of frozen Iranian funds, and that Iran’s principal conditions remained unchanged.

Those contacts follow talks in New York that failed to produce an agreement, with the two sides remaining divided over the terms for ending the war and reopening Hormuz.

For now, Trump has continued to present the choice as Iran’s: accept a deal under mounting military and economic pressure or face what he calls the “hard way.”

The prison in Karaj in western Tehran was one of the sites of the 1988 massacre of political prisoners. The exact nationwide toll remains unknown amid official secrecy, but rights groups estimate that around 5,000 people were executed across Iran.

Gohardasht was central to the prosecution of Hamid Nouri, a former Iranian prison official sentenced to life imprisonment by a Swedish court in 2022 for war crimes and murder over his role in the executions there. His conviction was upheld on appeal, but Sweden released him in June 2024 in a prisoner exchange with Iran.

Authorities have presented the prison’s redevelopment as a project to provide cultural facilities, university space and parks following its closure in 2023.

Warnings over destruction of evidence

When the prison closed in August 2023, the Norway-based Iran Human Rights organization called for urgent action to prevent its demolition, warning that evidence of atrocities could be lost before the full scope of the crimes was established.

“Gohardasht Prison is the place where crimes against humanity were committed by those who currently hold key positions in the Islamic Republic,” its director, Mahmood Amiry-Moghaddam, said at the time.

“We still don’t know the full scope of those crimes and destroying the evidence is without doubt one of the key motivations behind its closure.”

The organization described the closure as part of a systematic effort to erase traces of state crimes. Its warning came after Nouri’s conviction, while his appeal was still pending.

Executions at Rajaei Shahr continued long after the 1980s. Iran Human Rights said at least 530 people were executed there on murder charges alone between 2015 and 2022.

The group also cited reported efforts to destroy or alter Khavaran cemetery in southeastern Tehran, where victims of the 1988 massacre were buried in unmarked mass graves. Victims’ families had appealed to the UN human rights chief to prevent destruction or interference at the cemetery, it said.

Authorities promise parks and cultural facilities

A Saturday report by Iran’s state-linked Student News Network described the falling watchtower as the end of a familiar urban landmark. It did not address the prison’s role in the 1988 massacre or the warnings about preserving evidence.

Officials have justified the closure by citing a law requiring prisons to move outside cities, alongside complaints about prison-related traffic and other neighborhood problems.

Judiciary chief Gholamhossein Mohseni Ejei ordered the closure in April 2023. The prison was emptied by August that year, with prisoners transferred to Ghezel Hesar, according to the state media account.

Demolition of the perimeter walls began in the final month of the Iranian year ending in March 2026 and intensified in September, the report said. The head of Iran’s prisons organization described their removal as necessary to settle the land’s future and enable new projects.

Authorities say the roughly 60-hectare site will include green space, a women’s park, a cultural center, an auditorium and an art gallery. They have also pledged to retain the main prison building for university and cultural uses.
