GENEVA (Reuters) - Iran and six world powers reached a breakthrough agreement early on Sunday to curb Tehran's atomic ambitions in exchange for limited sanctions relief, in a first step towards resolving a dangerous decade-old standoff. The deal between the Islamic state and the United States, France, Germany, Britain, China and Russia was nailed down after more than four days of negotiations. "We have reached an agreement," Iranian Foreign Minister Mohammad Javad Zarif announced on his Twitter feed. French Foreign Minister Laurent Fabius also confirmed the deal.
No details of the agreement were immediately available. U.S. Secretary of State John Kerry and foreign ministers of the five other world powers joined the talks with Iran early on Saturday as the two sides appeared to be edging closer to a long-sought preliminary agreement. more
