Iran, IAEA and P5+1 slated for further nuclear talks in Vienna TEHRAN, Dec. 3 (UPI) -- Iranian Foreign Ministry spokeswoman Marziyeh Afkham said Tuesday another round of nuclear negotiations is scheduled next week in Vienna. "Iran and P5+1 expert negotiations will be held under the auspices of the International Atomic Energy Agency in Vienna on Dec. 9-10," she told the semiofficial Fars News Agency. P5+1 refers to the five permanent members of the U.N. Security Council -- United States, Russia, China, United Kingdom, and France -- plus Germany. November negotiations lead to an interim deal where Iran agrees to certain concessions on the enrichment of nuclear material in exchange for relief from some Western-imposed economic sanctions. Iran and the IAEA agreed in mid-November, before P5+1 negotiations, to "strengthen their cooperation and dialogue" in order to ensure the exclusively peaceful nature of Iran's nuclear program. The IAEA in reports this year said there may be a military dimension to Iran's nuclear program, an allegation it denies. U.S. President Barack Obama described the P5+1 agreement as "a first step" in a long diplomatic process. Iran and its negotiating partners will spend the next six months finding ways to address comprehensive concerns about Iran's nuclear ambitions, he said.
