A mysterious blast that shook a centrifuge workshop in Iran is still reverberating among international nuclear monitors who are now reporting that some of their surveillance equipment went missing following the June incident.
The International Atomic Energy Agency told diplomats in a restricted report that failure to recover its recording devices could imperil inspectors’ ability to reconstruct activity at the facility in the town of Karaj, located northwest of Tehran. The workshop produces components for centrifuges — the fast-spinning machines used to enrich uranium. Iran suspended IAEA access to the site in February but allowed cameras to continue filming and said the data would be given to inspectors if its nuclear agreement with world powers is restored.
