According to the sources, the International Atomic Energy Agency (IAEA) has apparently dropped the idea of a new report, at least for the time being.
The sources said there was no way of knowing what information collected by the agency since it issued a landmark report on Iran in 2011 might have been incorporated in the new document, although one said it could have added to worries about Tehran’s activities.
The IAEA’s dossier in November 2011 contained a trove of intelligence indicating past activity in Iran which could be used for developing nuclear weapons, some of which it said might still be continuing.
Since then the agency has said it obtained more information that backs up its analysis in the 2011 document, which detailed allegations ranging from explosives testing to research on what experts describe as an atomic bomb trigger.
One source said it was believed that the Vienna-based IAEA had received more information on suspicions of nuclear yield calculations, but it was not known to what extent this would have made it into a new report on Iran.
