Western powers are lobbying other states on the U.N. nuclear watchdog's board to jointly pressure Iran to give the agency the answers it has long sought on uranium traces found at three undeclared sites, diplomats said on Tuesday.
At its last quarterly meeting in June the International Atomic Energy Agency's 35-nation Board of Governors passed a resolution expressing "profound concern" that the traces remain unexplained due to insufficient cooperation by Iran, and calling on Tehran to engage with the watchdog "without delay".
