The Washington Post is reporting that Secretary of State Colin Powell relied on a single, unvetted source when he claimed Wednesday that he had new evidence thast Iran was developing a nuclear weapon. The report was entirely based on information provided by a source who approached US intelligence with 1,000 pages of documents that purportedly showed nuclear weapons drawings. One governmental official told the Washington Post that the CIA remains unsure about the authenticity of the documents and how they came into the informant’s possession. Powell’s comments came in direct contradiction to findings by the United Nations. The International Atomic Energy Association announced earlier this week it had seen no evidence that Iran was developing a nuclear weapons program.
