International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi said his agency does not know where nearly 900 pounds of potentially enriched uranium is located, after Iranian officials said it was being removed for protective measures ahead of strikes on nuclear facilities in Iran. Grossi said Natanz was the first to be hit and sustained “very serious damage” in one of the centrifuge halls where enrichment was being carried out. Isfahan also sustained damage, he added, though nobody has been inside the halls to assess the damage. He told the host Iran officials told him they were taking protective measures which may or may not include moving around the material.
