An Iranian exile group in France on Thursday released satellite images and details about what it claims are two sites used to research and build nuclear weapons in Iran. The claims could not immediately be verified.
The National Council of Resistance of Iran, a political arm of the Iranian opposition People's Mujahedeen Organization of Iran, said the sites are evidence that Iran is continuing and expanding nuclear activity despite international demands to halt it.
The International Atomic Energy Agency says it is investigating them. The Iranian Embassy in France would not comment.
