The report of the International Atomic Energy Agency (IAEA) published by a Washington think-tank on Tuesday repeated the sensational claim previously reported by news media all over the world that a former Soviet nuclear weapons scientist had helped Iran construct a detonation system that could be used for a nuclear weapon.

But it turns out that the foreign expert, who is not named in the IAEA report but was identified in news reports as Vyacheslav Danilenko, is not a nuclear weapons scientist but one of the top specialists in the world in the production of nanodiamonds by explosives.
