U.N. nuclear watchdog begins Tehran talks to secure access deal

DUBAI (Reuters) - Senior U.N. nuclear watchdog officials began talks in Iran on Wednesday to nail down an elusive deal for access to pursue a long-stalled investigation into suspected military dimensions to the Iranian nuclear programme.

The International Atomic Energy Agency, whose mission is to prevent the spread of nuclear weapons, has been trying for a year to negotiate a so-called structured approach with Tehran that would give it access to officials, documents and sites.
