In a 13-page summary late last year, the IAEA listed clandestine activities that he said can either be used in civilian or military nuclear programs, or "are specific to nuclear weapons."
Among these were indications that Iran has conducted high-explosives testing to set off a nuclear charge at Parchin â" a military site that the IAEA team was refused access to on both recent visits to Iran.
Other suspicions include computer modeling of a core of a nuclear warhead and alleged preparatory work for a nuclear weapons test and development of a nuclear payload for Iranâs Shahab 3 intermediate range missile â" a weapon that could reach Israel.
The report said Iran appeared to have a structured weapons-development program up to 2003; that some work continued past that date, "and that some may still be ongoing," adding that the agency believes its information on which its suspicions are based is "overall, credible."
