The Wall Street Journal: The United Nations nuclear watchdog will criticize Iran for misrepresenting the extent of its experiments with plutonium and for failing to answer outstanding questions about its nuclear program. The criticism, which will be presented in a speech today to the International Atomic Energy Agency board, is unlikely to scuttle European-led negotiations intended to wean Tehran of its alleged weapons ambitions.

Associated Press: Iran has acknowledged working with small amounts of plutonium, a possible nuclear arms component, for years longer than it had originally admitted to the U.N. atomic watchdog agency, according to a confidential report made available Wednesday to The Associated Press. The report, to be delivered as early as Thursday to a board meeting of the International Atomic Energy Agency, also said Tehran received sensitive technology that can be used as part of a weapons program earlier than it originally said it did.

Reuters: Iran has admitted to experimenting with producing plutonium, which can be used for atomic bombs, much more recently than it originally told the U.N. nuclear watchdog, according to a draft U.N. speech.
