VIENNA -- Iran has failed to answer questions about the discovery of uranium particles at former undeclared sites in the country, the head of the U.N. nuclear watchdog said Monday, 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 program. The issue is separate from the ongoing negotiations aimed at bringing the United States back into Iran's 2015 nuclear accord with world powers. Grossi said in March that Iran had agreed to sit down with international technical experts investigating the discovery, and said he hoped to “come to some satisfactory outcome” by the time of the IAEA board meeting in June.
