The International Atomic Energy Agency (IAEA) has voted to censure Iran for its nuclear defiance.
Diplomats inside the meeting said that 25 of the 34 IAEA board nations present voted for a resolution backed by the US, Russia, China, Britain, France and Germany.
The resolution criticises Iran for defying a UN Security Council ban on uranium enrichment - the source of both nuclear fuel and the fissile core of warheads.
It also censures it for secretly building a uranium enrichment facility and demands that it immediately suspend construction.
It notes that the IAEA cannot confirm that Tehran's nuclear programme is exclusively geared toward peaceful uses, and expresses "serious concern" that Iran may be hiding a military nuclear programme.
Iran insists its nuclear activities are peaceful but there are fears it could turn them to making nuclear arms.
