Iran's Zarif downplays chances of nuclear deal in Swiss talks

Iran's Foreign Minister Mohammad Javad Zarif on Wednesday played down the chances of reaching a nuclear agreement during talks under way in Switzerland.
Zarif said he did not expect foreign ministers from the other world powers involved in the negotiations would be required in Lausanne to approve a deal, after he held bilateral talks with US Secretary of State John Kerry.
"I don't think their presence will be needed in this round because when the solutions are found and we approach a deal, then all the foreign ministers of the negotiating parties should come," state media quoted him as saying.
