LAUSANNE, Switzerland (Reuters) - The foreign ministers of France and Germany joined the top U.S. and Iranian diplomats on Saturday to help break an impasse in nuclear negotiations as major powers and Iran closed in on a two- or three-page accord that could form the basis of a long-term deal.
The negotiations, in progress for nearly 18 months, aim to hammer out an accord whereby Iran halts sensitive nuclear work in exchange for the lifting of sanctions, with the ultimate aim of reducing the risk of a war in the Middle East.
