MUNICH (Reuters) - Iran's foreign minister held rare private talks with his U.S. counterpart on Sunday and said it would be a "disaster" if Tehran did not turn a provisional agreement to defuse a decade-old dispute over its nuclear programme into a permanent deal.
In a sign of the thawing climate between the Islamic Republic and the West, Iran's Mohammad Javad Zarif said he had held bilateral talks with U.S. Secretary of State John Kerry, as well as with other ministers from the six powers negotiating with Tehran, during a three-day security conference in Munich.
