relatively insignificant and coming too late." It was reported on 3 March 2008, that Olli Heinonen, the IAEA Deputy Director general of safeguards, had briefed diplomats about the contents of the "Alleged Studies" documents a week earlier. Reportedly, Heinonen added that the IAEA had obtained corroborating information from the intelligence agencies of several countries, that pointed to sophisticated research into some key technologies needed to build and deliver a nuclear bomb. In April 2008, Iran reportedly agreed to address the sole outstanding issue of the "Alleged Studies" However, according to the subsequent May 2008 IAEA report, the IAEA was not able to actually provide these same "Alleged Studies" documents to Iran, because the IAEA did not have the documents itself or was not allowed to share them with Iran. For example, in paragraph 21, the IAEA report states: "Although the Agency had been shown the documents that led it to these conclusions, it was not in possession of the documents and was therefore unfortunately unable to make them available to Iran." Also, in paragraph 16, the IAEA report states: "The Agency received much of this information only in electronic form and was not authorised to provide copies to Iran." The IAEA has requested that it be allowed to share the documents with Iran. Nevertheless, according to the report, Iran may have more information on the alleged studies which "remain a matter of serious concern" but the IAEA itself had not detected evidence of actual design or manufacture by Iran of nuclear weapons or components. Iran's refusal to respond to the IAEA's questions unless it is given access to the original documents has caused a standoff. In February 2008, The New York Times reported that the US refusal to provide access to those documents was a source of friction between the Bush Administration and then Director General ElBaradei. ElBaradei later noted that these documents could not be shared because of the need to protect sources and methods, but noted that this allowed Iran to question their authenticity. According to Iran's envoy to the IAEA, Ali Asghar Soltanieh, "The government of the United States has not handed over original documents to the agency since it does not in fact have any authenticated document and all it has are forged documents." The IAEA has requested that third parties allow it to share the documents on the alleged studies with Iran. The IAEA has
