US ambassador Gregory Schulte said the resolution "shows the international community is united in its determination that Iran move off the dangerous course it is on."

The International Atomic Energy Agency (IAEA) adopted Thursday by consensus an EU resolution calling on Iran to halt nuclear fuel development and leaving the door open to further talks if it complies.

IAEA spokeswoman Melissa Fleming said the resolution had been "adopted without a vote, by consensus."

Iran had earlier warned that its accord with the European Union over its nuclear program would become void if the IAEA adopted the resolution.

Iran signed an accord with the EU in Paris in November under which it agreed to suspend uranium conversion and enrichment fuel cycle work for the duration of negotiations aimed at securing guarantees that its program is purely peaceful.
