Iranian scientists experimented with technologies that could be used to make a nuclear bomb without ever taking the final steps needed to turn their work into a weapon, international investigators said in a landmark report aimed at ending a 12-year inquiry.

International Atomic Energy Agency monitors assessed that Iran ceased work that could be used to develop a weapon by 2009, the Vienna-based agency found in a restricted obtained Wednesday by Bloomberg News.
