Much of Iran's uranium likely to be in Isfahan: Grossi

PARIS (Reuters) -- Almost half of Iran's uranium enriched to up to 60 percent purity, a short step from weapons-grade, was stored in a tunnel complex at Isfahan and is probably still there, UN nuclear watchdog chief Rafael Grossi said Monday. The tunnel complex is the only target that appears not to have been badly damaged in attacks last June by Israel and the US on Iran's nuclear facilities. Diplomats have long said Isfahan has been used to store 60 percent uranium, which the International Atomic Energy Agency (IAEA) monitors.
