The world should be more worried about nuclear weapons falling into the hands of terrorists than about Iran's nuclear program, the head of the UN's nuclear watchdog agency said Friday. Mohamed ElBaradei, director of the International Atomic Energy Agency, said there is no military solution to the standoff with Iran over its determination to continue its uranium enrichment program. But he said the risk that terrorists could acquire a nuclear weapon was of greater concern. "Terrorists are a different thing," he said in an interview with the Dutch television program Netwerk. "The fear of terrorists acquiring nuclear weapons is much more, in my view ... than a country acquiring nuclear weapons right now," he said.
