Iran and six world powers sought common ground Friday at talks jeopardized by Tehran's refusal to discuss demands for curbs on nuclear activities that could enable it manufacture the fissile core of nuclear warheads. As the two sides broke for lunch, with the Iranians dining separately, there was no sign of movement from either side from widely differing positions revealed after a first round of talks in Geneva last month.
