VIENNA (Reuters) - Iran and six world powers began an expert-level meeting about Tehran's nuclear programme on Thursday, part of efforts to reach an agreement by late July on how to resolve a decade-old dispute that has stirred fears of a Middle East war.
The meeting in Vienna of nuclear and other experts from Iran and the United States, France, Germany, Russia, China and Britain was to prepare for a new round of higher-level negotiations next week, also in the Austrian capital.
