A senior Iranian diplomat said Friday nuclear negotiations in Geneva with world powers were moving closer to an accord after progress was made on the third day, media in Tehran reported. "To a good degree, we have moved (closer) towards agreement," deputy foreign minister Abbas Araqchi told reporters, according to the Mehr news agency. But he added, without elaborating, that despite "progress made today, some main issues still remain" in the diplomatic push to end a decade-long dispute over Iran's controversial nuclear drive.
