West 'agrees new Iran resolution'
Iran maintains that the purposes of its nuclear programme are peaceful
The foreign ministers of the five permanent members of the UN Security Council and Germany have agreed a draft resolution on Iran's nuclear programme.
Diplomats said the new resolution would reaffirm three earlier rounds of UN sanctions, and make it clear that the Security Council wants Iran to comply.
The agreement came after discussions between the US and Russia in New York.
On Wednesday, Iran's president warned it would resist "bullying powers" who tried to thwart its nuclear ambitions.
Addressing the UN General Assembly in New York, Mahmoud Ahmadinejad said his country supported dialogue but would not accept "illegal demands".
Western powers suspect Iran wants to build a nuclear weapons capability. Tehran says its nuclear programme is peaceful.
The UN Security Council has already imposed three packages of sanctions against Iran for defying its calls to halt uranium enrichment and plutonium reprocessing, and refusing to answer questions from the International Atomic Energy Agency (IAEA).
In a report last week, the agency said that without further information, it would not be able to provide assurances about Iran's nuclear programme to the international community.
