Iran builds at underground nuclear facility amid US tensions

  • Iran has not publicly acknowledged any new construction at Fordo
  • Under the 2015 nuclear deal, Iran agreed to stop enriching uranium at Fordo

DUBAI, United Arab Emirates: Iran has begun construction on a site at its underground nuclear facility at Fordo amid tensions with the US over its atomic program, satellite photos obtained Friday by The Associated Press show.
Iran has not publicly acknowledged any new construction at Fordo, whose discovery by the West in 2009 came in an earlier round of brinkmanship before world powers struck the 2015 nuclear deal with Tehran.
While the purpose of the building remains unclear, any work at Fordo likely will trigger new concern in the waning days of the Trump administration before the inauguration of President-elect Joe Biden. Already, Iran is building at its Natanz nuclear facility after a mysterious explosion in July there that Tehran described as a sabotage attack.
“Any changes at this site will be carefully watched as a sign of where Iran’s nuclear program is headed,” said Jeffrey Lewis, an expert at the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies who studies Iran.
Iran’s mission to the United Nations did not immediately respond to a request for comment. The International Atomic Energy Agency, whose inspectors are in Iran as part of the nuclear deal, also did not immediately respond to a request for comment.
Construction on the Fordo site began in late September. Satellite images obtained from Maxar Technologies by the AP show the construction taking place at a northwest corner of the site, near the holy Shiite city of Qom some 90 kilometers (55 miles) southwest of Tehran.
A Dec. 11 satellite photo shows what appears to be a dug foundation for a building with dozens of pillars. Such pillars can be used in construction to support buildings in earthquake zones.
The construction site northwest of Fordo’s underground facility, built deep inside a mountain to protect it from potential airstrikes. The site is near other support and research-and-development buildings at Fordo.
Among those buildings is Iran’s National Vacuum Technology Center. Vacuum technology is a crucial component of Iran’s uranium-gas centrifuges, which enrich uranium.
A Twitter account called Observer IL earlier this week published an image of Fordo showing the construction, citing it as coming from South Korea’s Korea Aerospace Research Institute.
The AP later reached the Twitter user, who identified himself as a retired Israeli Defense Forces soldier with a civil engineering background. He asked that his name not be published over previous threats he received online. The Korea Aerospace Research Institute acknowledged taking the satellite photo.
Trump in 2018 unilaterally withdrew the US from Iran’s nuclear deal, in which Tehran had agreed to limit its uranium enrichment in exchange for the lifting of economic sanctions. Trump cited Iran’s ballistic missile program, its regional policies and other issues in withdrawing from the accord, though the deal focused entirely on Tehran’s atomic program.
When the US ramped up sanctions, Iran gradually and publicly abandoned the deal’s limits as a series of escalating incidents pushed the two countries to the brink of war at the beginning of the year. Tensions still remain high.
Under the 2015 nuclear deal, Iran agreed to stop enriching uranium at Fordo and instead make it “a nuclear, physics and technology center.”
“This location was a major sticking point in negotiations leading to the Iran nuclear deal,” Lewis said. “The US insisted Iran close it while Iran’s supreme leader said keeping it was a red line.”
Since the deal’s collapse, Iran has resumed enrichment there.
Shielded by the mountains, the facility also is ringed by anti-aircraft guns and other fortifications. It is about the size of a football field, large enough to house 3,000 centrifuges, but small and hardened enough to lead US officials to suspect it had a military purpose when they exposed the site publicly in 2009.
As of now, Iran is enriching uranium up to 4.5%, in violation of the accord’s limit of 3.67%. Iran’s parliament has passed a bill that requires Tehran to enrich up to 20%, a short technical step away from weapons-grade levels of 90%. The bill also would throw out IAEA inspectors.
Experts say Iran now has enough low-enriched uranium stockpiled for at least two nuclear weapons, if it chose to pursue them. Iran long has maintained its nuclear program is peaceful.
While Iranian President Hassan Rouhani opposed the bill, the country’s Guardian Council later tweaked and approved it. The bill seeks to pressure European nations to provide relief from crippling US sanctions.
Meanwhile, an Iranian scientist who created its military nuclear program two decades ago recently was killed in a shooting outside of Tehran. Iran has blamed Israel, which has long been suspected of killing Iranian nuclear scientists over the last decade, for the attack. Israel has not comment.

Syrian military tells civilians to evacuate contested area east of Aleppo amid rising tensions

  • Syria’s military has announced it will open a “humanitarian corridor” for civilians to evacuate from an area in Aleppo province
  • This follows several days of intense clashes between government forces and the Kurdish-led Syrian Democratic Forces

DAMASCUS: Syria’s military said it would open a corridor Thursday for civilians to evacuate an area of Aleppo province that has seen a military buildup following intense clashes between government and Kurdish-led forces in Aleppo city.
The army’s announcement late Wednesday — which said civilians would be able to evacuate through the “humanitarian corridor” from 9 a.m. to 5 p.m. Thursday — appeared to signal plans for an offensive in the towns of Deir Hafer and Maskana and surrounding areas, about 60 kilometers (40 miles) east of Aleppo city.
The military called on the Kurdish-led Syrian Democratic Forces and other armed groups to withdraw to the other side of the the Euphrates River, to the east of the contested zone.
Syrian government troops have already sent troop reinforcements to the area after accusing the SDF of building up its own forces there, which the SDF denied. There have been limited exchanges of fire between the two sides, and the SDF has said that Turkish drones carried out strikes there.
The government has accused the SDF of launching drone strikes in Aleppo city, including one that hit the Aleppo governorate building on Saturday shortly after two Cabinet ministers and a local official held a news conference there.
The tensions in the Deir Hafer area come after several days of intense clashes last week in Aleppo city that ended with the evacuation of Kurdish fighters and government forces taking control of three contested neighborhoods. The fighting killed at least 23 people, wounded dozens more, and displaced tens of thousands.
The fighting broke out as negotiations have stalled between Damascus and the SDF, which controls large swaths of northeast Syria, over an agreement to integrate their forces and for the central government to take control of institutions including border crossings and oil fields in the northeast.
Some of the factions that make up the new Syrian army, which was formed after the fall of former President Bashar Assad in a rebel offensive in December 2024, were previously Turkiye-backed insurgent groups that have a long history of clashing with Kurdish forces.
The SDF for years has been the main US partner in Syria in fighting against the Daesh group, but Turkiye considers the SDF a terrorist organization because of its association with the Kurdistan Workers’ Party, or PKK, which has waged a long-running insurgency in Turkiye. A peace process is now underway.
Despite the long-running US support for the SDF, the Trump administration has also developed close ties with the government of interim Syrian President Ahmad Al-Sharaa and has pushed the Kurds to implement the integration deal. Washington has so far avoided publicly taking sides in the clashes in Aleppo.
The SDF in a statement warned of “dangerous repercussions on civilians, infrastructure, and vital facilities” in case of a further escalation and said Damascus bears “full responsibility for this escalation and all ensuing humanitarian and security repercussions in the region.”
Adm. Brad Cooper, commander of US Central Command, said in a statement Tuesday that the US is “closely monitoring” the situation and called for “all parties to exercise maximum restraint, avoid actions that could further escalate tensions, and prioritize the protection of civilians and critical infrastructure.” He called on the parties to “return to the negotiating table in good faith.”
Al-Sharaa blasts the SDF
In a televised interview aired Wednesday, Al-Sharaa praised the “courage of the Kurds” and said he would guarantee their rights and wants them to be part of the Syrian army, but he lashed out at the SDF.
He accused the group of not abiding by an agreement reached last year under which their forces were supposed to withdraw from neighborhoods they controlled in Aleppo city and of forcibly preventing civilians from leaving when the army opened a corridor for them to evacuate amid the recent clashes.
Al-Sharaa claimed that the SDF refused attempts by France and the US to mediate a ceasefire and withdrawal of Kurdish forces during the clashes due to an order from the PKK.
The interview was initially intended to air Tuesday on Shams TV, a broadcaster based in Irbil — the seat of northern Iraq’s semi-autonomous Kurdish region — but was canceled for what the station initially said were technical reasons.
Later the station’s manager said that the interview had been spiked out of fear of further inflaming tensions because of the hard line Al-Sharaa took against the SDF.
Syria’s state TV station instead aired clips from the interview on Wednesday. There was no immediate response from the SDF to Al-Sharaa’s comments.
