Iran says its nuclear programme will serve its energy needs
Iran has failed to co-operate with UN inspectors trying to establish if it has halted uranium enrichment, the head of the IAEA - the UN's nuclear watchdog - has said in a report.
Key members of the UN Security Council have reacted immediately. Here is a selection of their comments.
George W Bush, US President
I will consult and continue to consult with our allies on this issue.
It's very important for the Iranians to understand there is a common desire by a lot of nations in this world to convince them, peacefully convince them, that they ought to give up their weapons ambitions.
John Bolton, US Ambassador to the UN
If anything, the IAEA report shows that Iran has accelerated its efforts to acquire nuclear weapons, although of course the report doesn't make any conclusions in that regard.
I think we can say now the United States is ready to take action in the Security Council to move to a resolution, our feeling being that it should be a Chapter VII [of the UN Charter] resolution making mandatory for Iran the existing requirements of the IAEA resolutions.
Jack Straw, British Foreign Secretary
It is very serious that the Iranian regime has failed fully to co-operate with the [IAEA] and the United Nations Security Council.
We will now be asking the Security Council to increase the pressure on Iran so that the international community can be assured that its nuclear programme is not a threat to peace and
Wang Guangya, China's Ambassador to the UN
There are a lot of problems in the region and we should not do anything that would cause the situation to become even more complicated.
Sergei Kislyak, Russian Deputy Foreign Minister
We will very attentively examine the report to decide our position and further actions to solve problems linked to Iran's nuclear problem.
Philippe Douste-Blazy, French Foreign Minister
The report of Mr ElBaradei notes with regret that not only has Iran not responded to this reasonable demand but has, on the contrary, accelerated its enrichment programme.
That is a worrying situation for the international community. We continue, however, to say to Iran that the door to negotiations remains open.
It is up to the leaders of Iran to make the gestures that will re-establish confidence in the goals of their nuclear programme. We remain convinced that there must be a diplomatic
solution to this crisis.
