The U.N. nuclear watchdog is aware of all of Iran’s activities, the head of country's atomic energy organisation said on Friday, a day after the atomic agency's Board of Governors demanded explanation for traces of uranium at three undeclared sites.
The resolution, which was drafted on Thursday by the United States, Britain, France and Germany, said it was "essential and urgent" that Iran explain the origin of the uranium particles and more generally give the International Atomic Energy Agency all the answers it requires.
