VIENNA (Reuters) - Iran and six world powers haggled on Friday over the terms of extending negotiations on a nuclear deal for four more months after failing to bridge wide gaps on limits for Tehran's atomic programme, diplomats said.
It has been clear for several days that Iran, the United States, Britain, France, Germany, Russia and China would miss a July 20 deadline to reach a long-term accord on curbing Tehran's nuclear activities in exchange for a gradual end to international sanctions that have crippled the Iranian economy.
