Iran disputes UN finding that it worked on nuclear arms

Iran has rejected an assessment by the U.N. nuclear agency that it did past work on nuclear arms. But it is praising some aspects of the agency's investigation of the issue, reflecting its satisfaction that the more than decade-long probe has ended.

Closure of the file means that some questions about the alleged weapons work may never be resolved. But both Iran and the international community were eager to put the issue behind them in order to be able to implement a landmark nuclear deal that commits Tehran to limits on its nuclear activities in exchange for sanctions relief.

Implementation day will come once the U.N.'s International Atomic Energy Agency certifies that Iran has fulfilled its commitments. Diplomats said Monday that could happen within a week.
