U.S. Secretary of State John Kerry arrived in Geneva on Saturday (November 23) to join talks on Iran's contested nuclear programme, as Tehran and six world powers appeared to be on the verge of a breakthrough in the decade-old dispute.
The Chinese, French, British and German foreign ministers - Wang Yi, Laurent Fabius, William Hague and Guido Westerwelle - were due along with Kerry to take part in intense negotiations on a deal under which Iran would curb its atomic activity in exchange for some relief from economic sanctions.
The announcements came after diplomats in the Swiss city said a major sticking point in the talks, which began on Wednesday (November 20), may have been overcome.
A senior European diplomat told reporters earlier that foreign ministers of the six states would come to Geneva only if there was a deal to sign.
