Iran Defiant After UN Vote To Expand Sanctions --> The uranium-enrichment facility at Natanz (file photo) (MNA) March 26, 2007 -- Iran says it is cutting back its cooperation with the United Nations' nuclear watchdog agency and has again vowed it will not halt uranium enrichment.

The moves came in response to the UN Security Council's unanimous vote on March 24 to expand sanctions against Iran for refusing to halt-enrichment activity.

Iranian President Mahmud Ahmadinejad is quoted as calling the UN resolution "illegal" and pledging that Iran will not stop what he called its peaceful and legal nuclear work "even for one second."

Ahmadinejad also said Iran would not forget which nations supported the resolution and would adjust its international relations. No further details were given.

The new sanctions block Iranian arms exports, and impose an international freeze on the assets of 28 people and organizations involved in Iran's nuclear and missile programs. The measure says all sanctions would be suspended if Iran halts uranium enrichment.

On June 7, 2006, RFE/RL correspondent Charles Recknagel spoke with nuclear expert Shannon Kile of the Stockholm International Peace Research Institute in Sweden to help sort through some of the technical issues involved. "[Natanz] will be quite a large plant," Kile said. "There will be about 50,000 centrifuges and how much enriched uranium that can produce [is] hard to say because the efficiency of the centrifuges is not really known yet. But it would clearly be enough to be able to produce enough [highly-enriched uranium] for a nuclear weapon in fairly short order, if that's the route that they chose to go...." (more)
