VIENNA (AP) — Diplomats say Iran has shrouded a building that the U.N. nuclear agency suspects was used for secret work on nuclear weapons, meaning spy satellites can no longer monitor Tehran's alleged efforts to clean up the site.
For months, satellite images have recorded what the International Atomic Energy Agency suspects is an attempt to sanitize the site. At the same time, Iran has repeatedly rebuffed agency efforts for access — and did so again Friday.
The diplomats say the main building is now covered in plastic sheeting, shielding any activity there from the outside world. They demanded anonymity because they were not authorized to discuss the issue
Iran denies any interest in nuclear arms.
