The U.N. nuclear watchdog plans to start a "technical" dialogue with Iran aimed at advancing the process of obtaining explanations on outstanding issues such uranium particles found at old, undeclared sites, its chief said on Thursday.
"I'm ... aiming at having a far more clear understanding of this issue by the summer or before," International Atomic Energy Agency chief Rafael Grossi told a news conference, adding that the first meeting would be in Iran in early April and he hoped to report back to the IAEA board on progress by June.
