Implementation of the NPT Safeguards Agreement in the Islamic Republic of Iran, International Atomic Energy Agency, April 28, 2006 [reporting that Iran has enriched uranium in defiance of a March UN Security Council demand that it immediately suspend its nuclear enrichment program].

Excerpt:

All the nuclear material declared by Iran to the Agency is accounted for. Apart fiom the small quantities previously reported to the Board, the Agency has found no other undeclared nuclear material in Iran. However, gaps remain in the Agency's knowledge with respect to the scope and content of Iran's centrifuge programme. Because of this, and other gaps in the Agency's knowledge, including the role of the military in Iran's nuclear programme, the Agency is unable to make progress in its efforts to provide assurance about the absence of undeclared nuclear material and activities in Iran...

After more than three years of Agency efforts to seek clarity about all aspects of Iran's nuclear programme, the existing gaps in knowledge continue to be a matter of concern. Any progress in that regard requires full transparency and active cooperation by Iran - transparency that goes beyond the measures prescribed in the Safeguards Agreement and Additional Protocol - if the Agency is to be able to understand fully the twenty years of undeclared nuclear activities by Iran.
