The UN nuclear watchdog said Iran has started up new cascades of advanced centrifuges and planned to install others in the coming weeks. The June 14 report by the International Atomic Energy Agency (IAEA) was met with strong criticism by the United States and other Western nations. "We remain committed to a diplomatic solution preventing Iran from developing a nuclear weapon," the French Foreign Ministry said in a statement cosigned by Germany and Britain. The IAEA said its inspectors verified that Iran had begun feeding uranium into three cascades of advanced centrifuges at its Natanz enrichment facility. Its report, however, did not include any suggestion Iran planned to go to higher enrichment levels.
