U.N. nuclear chief presses Iran on military base access

VIENNA (Reuters) - The U.N. nuclear watchdog raised pressure on Iran to finally address suspicions that it has sought to design an atomic bomb, calling for swift inspector access to a military base where relevant explosives tests are believed to have been carried out.

Airing frustration at the lack of progress in his agency's investigation, Yukiya Amano told its 35-nation governing board on Monday that negotiations with Iran must "proceed with a sense of urgency" and be focused on achieving concrete results soon.
