Herman Nackaerts, Deputy Director General and Head of the Department of Safeguards of the International Atomic Energy Agency, IAEA, waves as he arrives from Iran at Vienna's Schwechat airport, Austria, on Friday, Dec. 14, 2012. Nackaerts says his team made headway during talks in Tehran meant to restart an investigation of suspicions the Islamic Republic may have secretly worked on a nuclear arms program. He says that means the U.N. nuclear agency expects to resume its probe early next year. (AP Photo/Ronald Zak)
