have come from leaking used highly enriched uranium fuel from the Tehran Research Reactor, which the U.S. supplied to Iran in 1967, and the matter was closed. In July 2007 the IAEA announced that Iran has agreed to allow inspectors to visit its Arak nuclear plant, and by August 2007 a plan for monitoring the Natanz uranium enrichment plant will have been finalised. In August 2007 the IAEA announced that Iran has agreed to a plan to resolve key questions regarding its past nuclear activities. The IAEA described this as a "significant step forward". In September 2007 the IAEA announced it has been able to verify that Iran's declared nuclear material has not been diverted from peaceful use. While the IAEA has been unable to verify some "important aspects" regarding the nature and scope of Iran's nuclear work, the agency and Iranian officials agreed on a plan to resolve all outstanding issues, Director-General Mohamed ElBaradei said at the time. In an interview with Radio Audizioni Italiane the same month, ElBaradei remarked that "Iran does not constitute a certain and immediate threat for the international community".

In late October 2007, according to the International Herald Tribune, the former head of the IAEA, Mohamed ElBaradei, stated that he had seen "no evidence" of Iran developing nuclear weapons. The IHT quoted ElBaredei as stating that, "We have information that there has been maybe some studies about possible weaponization," said Mohamed ElBaradei, who led the International Atomic Energy Agency. "That's why we have said that we cannot give Iran a pass right now, because there is still a lot of question marks." "But have we seen Iran having the nuclear material that can readily be used into a weapon? No. Have we seen an active weaponization program? No." The IHT report went on to say that "ElBaradei said he was worried about the growing rhetoric from the
