IAEA urges Iran to provide information on uranium traces at sites

UN nuclear watchdog chief’s remarks come as Tehran and world powers try to salvage a 2015 agreement.

Iran has failed to answer questions about the discovery of uranium particles at former undeclared sites in the country, the head of the UN nuclear watchdog has said, calling on Tehran to provide information “without further delay”. Rafael Grossi, the head of the International Atomic Energy Agency, has been pushing Iran for answers on three sites dating back many years where inspections had revealed traces of uranium of man-made origin, suggesting they were once connected to Iran’s nuclear programme. The issue is separate from the continuing negotiations aimed at bringing the United States back into Iran’s 2015 nuclear accord with world powers.
