Iran is “dramatically” increasing the amount of uranium enriched to up to 60 percent purity, close to the roughly 90 percent of weapons grade, that it is able to produce, the watchdog’s chief Rafael Grossi told Reuters in an interview. The move is certain to cause even greater alarm in Western capitals already arguing that there is no civil justification for Iran’s enrichment to that level as no other country has done so without producing nuclear bombs, which Iran denies pursuing. Iran already has enough material enriched to up to 60 percent, its most highly enriched stock, for four nuclear weapons in principle if it enriched it further, according to an IAEA yardstick. It has enough for more at lower enrichment levels.For all the latest headlines, follow our Google News channel online or via the app. “Today the agency is announcing that the production capacity is increasing dramatically of the 60 percent inventory,” International Atomic Energy
