Syria no longer under UN nuclear watchdog probe

By the Editorial Team · Thursday, September 10, 2026

The International Atomic Energy Agency has ended its investigation into Syria’s nuclear program after the current government allowed unprecedented access to previously restricted sites, including a nearly complete reactor at Deir Ezzor built under the former regime. This move signals increased transparency from Syria and a shift toward resolving long-standing concerns, though full compliance with nuclear obligations remains unconfirmed.

The International Atomic Energy Agency (IAEA) has officially ended its longstanding investigation into Syria’s nuclear activities, following unprecedented cooperation from the country’s current authorities. The decision was announced on Wednesday by the IAEA board of governors, which voted by consensus to terminate a 2011 resolution that had found Syria in non-compliance with its nuclear obligations during the regime of former President Bashar Assad.

The resolution, originally submitted by Egypt, Jordan, Morocco, and Saudi Arabia, called on Syria to cooperate with the UN nuclear watchdog, including permitting excavation at key sites suspected of undeclared nuclear activity. In recent months, IAEA inspectors were granted access to two locations in Syria—one in Deir Ezzor and another undisclosed site—that had previously been off-limits. Upon inspection, experts found a nearly complete nuclear reactor at Deir Ezzor, which had been clandestinely constructed during Assad’s rule, with indications suggesting possible North Korean involvement.

IAEA Director General Rafael Grossi characterized the prior Syrian regime’s nuclear endeavors as “a number of clandestine” projects that could have enabled the production of fissile material suitable for weapons. He commended the current Syrian government for its “courageous decision” to disclose an additional site not previously reported to the agency.

The 2011 resolution stemmed from the IAEA’s assessment that the Deir Ezzor facility was “very likely” a nuclear reactor, with suspicions it was under construction with assistance from North Korea. Though the reactor was later destroyed, the extent of Syria’s weapons ambitions has remained unclear. According to Robert Kelley, a former head of IAEA inspections and now an associate fellow at the Stockholm International Peace Research Institute, the current evidence does not confirm an active weapons program. Instead, he suggested the facility might have aimed to produce plutonium potentially intended for sale, possibly involving North Korea and third-party actors.

As part of the board’s decision, the resolution was formally terminated, while urging Damascus to sustain its engagement with the IAEA, including cooperation with continued excavation efforts at Deir Ezzor. The agency’s leadership will provide updates on ongoing activities in Syria as warranted.

This development marks a significant shift in the monitoring of Syria’s nuclear program, stemming from enhanced transparency and cooperation by the new Syrian authorities. The closure of the probe does not imply a declaration of the country’s full compliance with all nuclear obligations but signals progress toward clarifying previously opaque activities.
