There are still "significant gaps" between Iran and the Six Powers in its nuclear talks, US Secretary of State John Kerry has said, as foreign ministers from Britain, the US, France, Germany, Russia and China met in Vienna to discuss Tehran's nuclear programme.
Mr Kerry's sentiments were echoed by Iranian deputy foreign minister Abbas Araqchi, who was quoted by state television, saying: "Disputes over all major and important issues still remain. We have not been able to narrow the gaps on major issues and it is not clear whether we can do it."
