A top official said only a few grams an hour of uranium gas would be enriched up to 60% purity — triple the level it once did but at a rate far slower than what Tehran could produce. International inspectors already said Iran planned to do so above-ground at its Natanz nuclear site, not deep within its underground halls hardened to withstand airstrikes... Mohammad Bagher Qalibaf, Iran's parliament speaker, announced the move in a Twitter post later acknowledged by Iranian state television. "The young and God-believing Iranian scientists managed to achieve a 60% enriched uranium product," Qalibaf said. "I congratulate the brave nation of Islamic Iran on this success. The Iranian nation’s willpower is miraculous and can defuse any conspiracy." The head of the Atomic Energy Organization of Iran, the country's civilian nuclear arm, later acknowledged the move to 60%, according to state TV. Ali Akbar Salehi said the centrifuges now produce 9 grams an hour, but that would drop to 5 grams an hour in the coming days.
