Iran, world power nuclear talks start in Vienna

Talks between Iran and six world powers aimed at agreeing a lasting nuclear deal resumed in Vienna on Tuesday. The parties aim to transform by July an interim accord struck in November into a final deal that resolves for good the decade-old standoff over Iran's nuclear programme. Iran, six powers seek nuclear progress in shadow of Ukraine crisis. So far, diplomats say, there is little sign that the worst East-West confrontation since the Cold War will undermine the quest for a deal to end the standoff over Iran's atomic activity and avert the threat of a Middle East war, according to AFP
