Iran announced Tuesday that it has started converting raw unranium into the gas needed for enrichment. "Tests are going on successfully" to make uranium hexafluoride gas, the feed stock for enrichment, said Iranian Vice President Reza Aghazadeh. Of the more than 40 tons of raw uranium being mined for conversion, "Some... has been used," he told reporters. His comments, outside the 137-nation IAEA general conference was the latest sign that Iran was ignoring demands made on the weekend by the agency's board of governors to suspend all enrichment and related activities.
