The agency said it would continue to monitor the activities at the site “as the excavation work progresses”.Syria was believed to have operated an extensive undeclared nuclear programme under al-Assad that included a nuclear reactor built by North Korea in Deir Az Zor.The site only became public knowledge after Israel launched air strikes in 2007 that destroyed the facility. Syria later levelled the site and never responded fully to the IAEA’s questions about it.Israel is believed to have its own undeclared atomic weapons programme that makes it the only country in the Middle East with nuclear bombs. Israel neither confirms nor denies having atomic weapons.Syrian Foreign Minister Asaad Al-Shaibani speaks during a joint news conference with Rafael Grossi, director general of the International Atomic Energy Agency (IAEA), in the former presidential Tishreen Palace in Damascus, Syria, August 18 [Mohamed Al Rifai/EPA]Following al-Assad’s removal in early December 2024, the new government agreed to give IAEA inspectors access to suspected former nuclear sites.The agency took samples at the site in 2024 and reported last year that they contained uranium particles.In its Tuesday report, the IAEA said it was also able to “establish that the former Syrian authorities had failed to report nuclear material, facilities and activities”.Besides the nuclear reactor under construction at Deir Az Zor, the IAEA listed a fuel fabrication plant, where the nuclear fuel for the reactor was manufactured, and a location where the nuclear fuel, as well as uranium scrap and waste, were stored.During the visit to Syria, IAEA Director General Rafael Grossi and a team of senior inspectors also visited a previously undeclared site.The new Syrian administration notified the agency of the site’s existence in a July 17 letter and invited the IAEA “to cooperate with the Syrian authorities in the inspection and verification of the site and of any nuclear material to be potentially found”.The IAEA said in its report that this new site contained “natural uranium metal in the form of fuel rods with cladding”.The agency verified the material and confirmed “the presence of around 73 tonnes of natural uranium metal”. The agency reported that “all of this nuclear material is currently subject to Agency containment and surveillance measures”.The new Syrian authorities have also expressed an interest in developing a civilian nuclear energy programme and said any nuclear material found in the country would remain in Syria’s custody under international safeguards.
