VIENNA (Reuters) - The United States called on Iran on Wednesday to dilute all of the uranium it has enriched to up to 60% purity, close to the weapons-grade level of roughly 90%, in a statement denouncing many of Tehran's recent nuclear moves.
The International Atomic Energy Agency said in a confidential report to member states last week that Iran's stock of uranium enriched to up to 60% had fallen slightly in the past quarter as it had diluted, or "downblended", more of its most highly enriched material than it had produced.
