BBC: Iranian President Mahmoud Ahmadinejad has said that a US report on Tehran's nuclear programme is a "great victory".
He said in a televised speech that Iran would not retreat from its path towards a peaceful atomic programme.
The US intelligence report released on Monday said that Iran had halted a nuclear weapons programme in 2003.
The US and its European allies are pushing for UN sanctions but China has said the report raises questions about the need for new measures.
US President George W Bush said on Tuesday that Iran remained a threat and his view that a nuclear Iran would be a danger "hasn't changed".
'Final blow'
Mr Ahmadinejad made his televised speech in front of thousands of people during a visit to Ilam province in western Iran.
"This report... is announcing a victory for the Iranian nation in the nuclear issue against all international powers," he said. Nuclear report a victory – Iran >>>
