VIENNA (Reuters) - The United Nations nuclear watchdog said on Monday Iran had begun implementing transparency measures ahead of an Aug 25 deadline, as part of a long-running investigation into suspected atomic bomb research by Tehran.
Yukiya Amano, speaking at Vienna airport after talks with Iranian President Hassan Rouhani in Tehran on Sunday, said he expected progress by Monday over the measures it agreed three months ago.
