US Secretary of State John Kerry arrived in Vienna Sunday to face off with Iranian counterpart Mohammad Javad Zarif, seven days before a deadline to strike a historic but elusive-looking deal on Tehran`s suspect nuclear programme.
Iran and world powers have less than two weeks to reach an agreement on the future scope of Iran`s uranium enrichment programme and other issues if they are to meet a self-imposed July 20 deadline for a deal.
Direct talks with the United States this week on Tehran`s nuclear programme hold the key to bridging gaps at a "serious phase" of negotiations and sealing a deal, a top Iranian official said on Sunday.
Iranian, U.S. and European Union officials will start two days of talks about Tehran`s nuclear programme on Monday, Iran said, giving its first word about what appears to be a bid to rescue faltering wider negotiations on ending a decade-old dispute.
IAEA, Iran make progress on nuclear bomb probe
Vienna: Iran has agreed to address some of the many long-held allegations that it conducted research into making nuclear weapons before 2003 and possibly since, the UN atomic watchdog said today.
Nuclear experts from Iran and six world powers had "a useful meeting" in New York ahead of political talks next week aimed at reaching an agreement to limit Iran`s ability to produce nuclear weapons, the European Union has said.
