Iranian envoy says UN resolution 'disappointing'

The Iranian envoy to the International Atomic Energy Agency (IAEA) says a UN resolution about his nation's nuclear programme will "discourage us from taking further voluntary steps".

The IAEA resolution expressed "deep and increasing concern" and called on Iran to clear up outstanding questions about its nuclear capabilities.

Ali Ashgar Soltanieh told the BBC the move was counter-productive, saying it was a "regretful, disappointing... politically motivated resolution which has nothing in it."
