Duck and cover: The U.N. nuclear agency announced Thursday new fears that Iran may be building a nuclear weapon. The report puts the U.N. with Germany, France, Britain, and Israel in disagreeing with a three-year-old U.S. intelligence assessment that said Iran stopped building a warhead in 2003. The U.N. says that Iran’s opposition to its probes "give[s] rise to concerns about possible military dimensions to Iran's nuclear program."
