The International Atomic Energy Agency (IAEA), the United Nations nuclear watchdog, has concluded that Syria built a nuclear reactor in Deir Az Zor during the rule of former President Bashar al-Assad, according to Al Jazeera.
The watchdog said Syria ‘failed to report nuclear material, facilities and activities’ under al-Assad’s government, according to the same report.
Al Jazeera reported the IAEA’s assessment on 2 September 2026. The report attributes the finding to activity that took place while al-Assad was in power.
Beyond the reactor’s location in Deir Az Zor and the conclusion that it was undeclared, further technical details were not provided in the available reporting. It is not yet clear from the sources when the IAEA reached its conclusion, what evidence it cited, or whether Syria’s current authorities have responded.
