Iran chief negotiator leaves for nuclear talks

Iran's chief negotiator said he was adopting a positive approach as he headed on Wednesday to potentially make-or-break talks with world powers on his country's controversial nuclear programme. We are going to Europe for this negotiation with a positive approach and I hope this is an opportunity for others also, Saeed Jalili told reporters at Tehran airport before leaving for Thursday's negotiations in Geneva. The UN Security Council has imposed three sets of sanctions against Iran over its failure to heed repeated ultimatums to suspend enrichment.
