Iran is ready to double the output at its underground uranium enrichment facility, the UN nuclear watchdog says.
A leaked report by the International Atomic Energy Agency (IAEA) said there were 2,784 centrifuges at Fordo, and that Iran could soon double the number operating from 700 to 1,400.
The development is likely to fuel Western suspicions that Iran is seeking to develop nuclear weapons.
The government in Tehran insists the nuclear programme is entirely peaceful.
