U.S. Secretary of State John Kerry and his Iranian counterpart, Foreign Minister Mohammad Javad Zarif, have met in Geneva for talks meant to pave the way for a comprehensive nuclear agreement by the end of June.
Kerry and Zarif had a "thorough and comprehensive discussion of all of the issues today," a senior State Department official said on May 30.
Abbas Araghchi, deputy head of Iran's negotiating team, was quoted as saying, "The differences are still there."
The six-hour talks follow a preliminary deal reached April 2 between Iran and six world powers -- the United States, China, Russia, France, Britain, and Germany -- on the outlines of a deal aimed at getting Iran to curb its nuclear activities in exchange for sanctions relief.
The six want limits on Tehran's programs that could have a military use. Tehran denies it is pursuing such weapons.
