Six world powers and Iran will begin talks in Vienna on February 18 on a long-term deal for Tehran to curb parts of its nuclear programme in exchange for a gradual end to sanctions, European Union foreign policy chief Catherine Ashton said on Friday, Reuters reported.
"We have agreed that we will start the talks on February 18 at the U.N. building in Vienna," Ashton said after talks with Iranian Foreign Minister Mohammad Javad Zarif on the sidelines of the Munich security conference.
