How Iran Spent Its Summer Vacation

From “Report Details Progress By Iran at Nuclear Bunker,” David E. Sanger and William J. Broad, NYT:

“Iran has installed three-quarters of the nuclear centrifuges it needs to complete a site deep underground for the production of nuclear fuel….

“The report by the International Atomic Energy Agency, the last to be issued before the American presidential election, lays out in detail how Iran over the summer has doubled the number of centrifuges installed deep under a mountain near Qum.  Iran has also, the report said, cleansed another site where the agency has said it suspects that the country has conducted explosive experiments that could be relevant to the production of a nuclear weapon.”
