What happened

Israel destroyed the suspected undeclared reactor at Dair Alzour (Al-Kibar) on 6 September 2007. The IAEA later assessed that the destroyed building was very likely a nuclear reactor that Syria should have declared. Inspectors collected environmental samples in 2024 at three other locations alleged to have been functionally connected to Dair Alzour; results reported in September 2025 identified a significant number of anthropogenic natural-uranium particles at one of them. On 11 August 2026, Syria's Atomic Energy Commission said an IAEA delegation was expected to announce significant progress on the country's legacy nuclear-material file. A Syrian official told Reuters that consultations were continuing and no final agreement had been concluded. Separate Axios reporting said the IAEA planned to remove material from an unnamed clandestine site, but stated on 10 August that it had not yet been removed. This Damascus-positioned marker is a national reference: neither the sampled associated location nor the currently reported storage site is publicly identified here. The record does not indicate an operating reactor, a confirmed radiation leak, a new attack or a completed material removal.
