Iran is multiplying the pace at which it is enriching uranium to close to bomb-grade, mainly at its Fordow site dug into a mountain, the UN nuclear watchdog said in a confidential report to member states on Friday.
The International Atomic Energy Agency verified on Thursday that Iran had started feeding uranium hexafluoride gas enriched to up to 20% instead of the previous 5% into two interconnected cascades of IR-6 centrifuges at Fordow enriching to up to 60%, close to the roughly 90% of weapons-grade, the report said.
