The U.N. nuclear agency says Iran has rapidly ramped up production of higher-grade enriched uranium over the last four months. Its confidential report feeds concerns about how quickly the Islamic Republic could produce an atomic bomb. Friday's Feb. 24, 2012 report by the International Atomic Energy Agency also said that Iran had failed to give a convincing explanation about a quantity of missing uranium metal. Diplomats have said the missing amount could be used for experiments used to arm a warhead. (AP Photo/Ronald Zak, File)
