Experts from Iran and the five permanent members of the UN Security Council - the United States, China, Russia, France and Britain - plus Germany will hold a fresh round of talks from May 5-9 over technical issues in a bid to reach a consensus, ISNA reported.

Tehran and the six countries wrapped up their latest round of high-level nuclear talks in Vienna on April 9.
Negotiations between Iran and the P5+1 group are aimed at reaching a final agreement to fully resolve the West’s decade-old dispute over Tehran’s nuclear energy program. 
Iran and the six world powers sealed an interim deal in Geneva on November 24, 2013 to pave the way for the full resolution of the decade-old dispute with Iran over the country’s nuclear energy program. The deal came into force on January 20.
Under the Geneva deal , dubbed the Joint Plan of Action, the six countries have undertaken to provide Iran with some sanctions relief  in exchange for the Islamic Republic agreeing to limit certain aspects of its nuclear activities during a six-month period.
