Iran should “understand the message” that it needs to do more to address global concerns that it wants the bomb, following the U.N. atomic agency’s latest board resolution, the watchdog’s chief said Thursday, September 13, Agence France Presse reported. “I hope that Iran clearly understands the message and engages with us on substance,” International Atomic Energy Agency Director General Yukiya Amano said. On Thursday the IAEA’s 35-nation board of governors approved with a crushing majority a resolution of “serious concern” that Iran continues to defy U.N. Security Council resolutions calling for a suspension of uranium enrichment. The resolution also highlighted the IAEA’s complaint that activities spotted at the Parchin military base, where it suspects nuclear weapons research took place, would “significantly hamper” inspectors – should Iran let them visit.
