UNITED NATIONS (Reuters) - The United States and five other major powers are closer than ever to a deal with Iran that would end a 12-year-old standoff over Tehran's nuclear programme, though more tough negotiations lie ahead, U.S. Secretary of State John Kerry said on Monday.
Kerry spoke at the United Nations on the opening day of a month-long conference taking stock of the 1970 nuclear Non-Proliferation Treaty and ahead of a meeting in New York with Iranian Foreign Minister Mohammad Javad Zarif, their first face-to-face encounter since recent marathon talks in Lausanne, Switzerland.
