The head of Iran’s Atomic Energy Organization said Sunday Iran plans to build ten new uranium enrichment facilities during the next year. The move is expected to further raise tension with the West. The Iranian official, Ali Akbar Salehi, also said Iran would start producing uranium enriched to a level of 20 percent on Tuesday, in the presence of inspectors from the International Atomic Energy Agency. But Salehi also suggested production would be halted if Iran received fuel enriched to 20 percent from abroad.
