BBC: US President George W Bush has said that Iran should reveal the full extent of its nuclear programme, or risk further international isolation.
A US intelligence assessment released on Monday said that Iran had halted a nuclear weapons programme in 2003.
Iranian President Mahmoud Ahmadinejad called the US report a "great victory" for Iran.
But Mr Bush said Iran still had "more to explain" about its past actions, and that it must cease uranium enrichment.
He said Iran had yet to acknowledge that it had a covert nuclear weapons programme which ran until 2003 - as stated by Monday's National Intelligence Estimate (NIE).
The report said Iran was keeping its options open, continuing to enrich uranium, which could be used for nuclear weapons in the future. Bush urges Tehran to come clean >>>
