French Foreign Minister Laurent Fabius

French Foreign Minister Laurent Fabius is returning Wednesday to Switzerland to crunch nuclear talks with counterparts from Iran and other major powers, the French foreign ministry said as negotiations headed into a another night of hard bargaining.
German Foreign Minister Frank-Walter Steinmeier said earlier Wednesday that Fabius would return to Lausanne, joining US Secretary of State John Kerry and Britain's Philip Hammond, "once (the talks) enter a decisive stage."
