VIENNA – The U.N's top nuclear official is expressing concern that Iran may be secretly continuing work on nuclear weapons.
International Atomic Energy Agency chief Yukiya Amano tells The Associated Press that his agency has indications of such activities both "in the past and now."
Iran denies secret weapons work and even the United States — which provides much of the intelligence on Iran to the agency — said in 2007 that Tehran had suspended all meaningful weapons development by 2003.
Since then, however, IAEA reports have listed suspicions of tests and experiments well past that date
But Amano's comments Tuesday appeared to be the most specific in suggesting such work is proceeding into the present.
