A senior official on Monday said the UN nuclear agency believes Iran plans to start enriching uranium at the previously secret Qom nuclear facility in 2011.
The International Atomic Energy Agency (IAEA) also believes that the site near the holy city of Qom will be able to house 3,000 uranium-enriching centrifuges, said the official.
A senior international official familiar with a new IAEA report said that number could allow Iran to enrich enough material to be able to arm one nuclear warhead a year. He spoke on condition of anonymity because of the restricted nature of the information.
Iran denies it wants a nuclear weapons program, saying it is enriching uranium only in order to create nuclear fuel.
