The BBC's Kim Ghattas reports that the agreement between the US and Russia on a draft text has been seen as a historic breakthrough, but there are more obstacles before the resolution is passed.
By calling for a meeting on Monday on the creation of an international stabilisation force, before a ceasefire resolution is passed, Washington and London hope to put pressure on other world leaders to back their calls for a ceasefire.
He gave the same gloomy prognosis to the foreign secretary, Jack Straw, on 7 November, the day before the resolution was passed.
Before the resolution was passed, the IAEA director general, Yukiya Amano, summarised the findings of the investigation – that Iran had a concerted weapons design effort up to 2003, and there were some sporadic activities after that.
In negotiating a new resolution, the Americans and the British had originally wanted any Iraqi violation of the weapons-inspection regime to be punishable by force, and the French, backed by Russia and a comparatively disinterested China, wanted to require that a second resolution be passed before military action might be taken.
That resolution was passed following concern that Iran had failed to satisfy previous resolutions and IAEA requirements.
Resolutions were passed and accepted unanimously.
Resolutions were passed mandating Iraq's disarmament.
