UN agency asks Iran to clear up 'ambiguities' in probe of Tehran's alleged past nuke arms work

The U.N. nuclear agency is asking Iran to clear up "ambiguities" in answers Tehran provided over allegations of past work on atomic arms.

The International Atomic Energy Agency request published Wednesday comes after Iran handed over documents and explanations in August for the newest IAEA attempt to probe the allegations.

Back then, diplomats said the agency received more than 100 pages of documentation, some of it old. Iran has consistently dismissed the suspicions as false, and the diplomats said initial indications suggested that much of the information provided last month also was aimed at repudiating the allegations.

The diplomats demanded anonymity because they are not authorized to discuss confidential information.

Iran nuclear sanctions won't be fully lifted before the 35-nation IAEA board receives a final IAEA assessment, planned for December.
