GENEVA, Nov. 8 (Xinhua) -- The European Union foreign policy chief Catherine Ashton has held discussions with French Foreign Minister Laurent Fabius Friday during the intensive talks between world powers and Iran, said her spokesman Michael Mann. Fabius flew to Geneva Friday to join the talks between five permanent members of the United Nations Security Council, Britain, China, France, Russia and the United States, plus Germany and Iran over the latter's controversial nuclear program. U.S. Secretary of State John Kerry, British Foreign Secretary William Hague, and German Foreign Minister Guido Westerwelle are also making unscheduled trips to Geneva to join the talks, which has raised the hope that an interim deal will be made after the negotiations. Kerry told reporters upon arrival Friday afternoon that there was not an agreement made yet between the two sides at this point of time and he came to "work with our colleagues to see if we can narrow some differences." "I want to emphasize there are still some very important issues on the table that are unresolved," he stressed, adding that the P5 was working hard. He will meet Ashton, other foreign ministers, as well as Iranian Foreign Minister Mohammad Javad-Zarif.
