Inspectors from the U.N.'s atomic watchdog have confirmed Iran has started building an underground centrifuge assembly plant after its previous one exploded in what Tehran called a sabotage attack over the summer, the agency's head told The Associated Press on Tuesday.
Iran also continues to stockpile greater amounts of low-enriched uranium, but does not appear to possess enough to produce a weapon, Rafael Grossi, director-general of the International Atomic Energy Agency, told the AP in an interview in Berlin.
