German Chancellor Angela Merkel said today Iran remained a threat.
"Iran continues to represent a threat," Ms Merkel said at a joint news conference with French President Nicolas Sarkozy in Paris.
The US National Intelligence Estimate, released on Monday, appeared to contradict past assertions by the administration of US President George W. Bush that Iran is intent on building a bomb.
US Secretary of State Condoleezza Rice today also urged a sceptical Russia to help maintain pressure on Iran.
Ms Rice, in Brussels for a meeting of Nato ministers, plans to hold talks on Friday with Russian Foreign Minister Sergei Lavrov, who has said any new sanctions plans against Iran must take the new intelligence report into account.
"I don't see that the NIE [National Intelligence Estimate] changes the course that we are on," said Ms Rice, who along with Britain and France is pushing for a third UN Security Council resolution against Iran.
But the intelligence report appears to contradict the Bush administration's past assertions that Iran is intent on building a bomb and makes it more difficult for Ms Rice to campaign for greater isolation of Tehran.
The report found Tehran halted its atomic weapons program in 2003.
In her discussions with Mr Lavrov, Ms Rice said she would argue that the report's suggestion that Iran abandoned its nuclear arms work in 2003 showed that it responded to pressure, and this was a reason to maintain the isolation.
