Subsidiary Arrangements to its Safeguards Agreement. ElBaradei closed by saying international negotiations represented a "unique opportunity to address a humanitarian need and create space for negotiations". On 18 February 2010 the IAEA released a new report on Iran's nuclear program. Ivan Oelrich and Ivanka Barzashka, writing in the Bulletin of the Atomic Scientists, suggested "the media has seriously misrepresented the actual contents of the report" and that "in fact, no new information has been revealed." They wrote that there was "no independent assessment that Iran is engaged in weapons work" and that this was "hardly the first time that the agency has discussed potential evidence of Tehran's nuclear weapons research". Iran's envoy to the UN atomic watchdog criticized Western powers for interpreting the IAEA report in an "exaggerated, selective and inaccurate" manner. In an April 2010 interview with the BBC, former IAEA Director General ElBaradei said Western nations were seeking harsher sanctions "out of frustration". "I don't think Iran is developing, or we have new information that Iran is developing, a nuclear weapon today .. there is a concern about Iran's future intentions, but even if you talk to MI6 or the CIA, they will tell you they are still four or five years away from a weapon. So, we have time to engage," he said. ElBaradei further said the building of trust between the parties would "not happen until the two sides sit around the negotiating table and address their grievances. Sooner or later that will happen." Alleged weaponization studies Former IAEA Director General ElBaradei said in 2009 that the agency had been provided with "no credible evidence" that Iran is developing nuclear weapons, but the New York Times reported in January 2009 that the IAEA is investigating U.S. allegations Project 110 and Project 111 could be names for Iranian efforts for designing a nuclear warhead and making it work with an Iranian missile. "We are looking to those suppliers of information to help us on the question of authenticity, because that is really a major issue. It is not an issue that involves nuclear material; it's a question of allegations," ElBaradei further said. ElBaradei has strongly denied reports that the agency had concluded Iran had developed technology needed to assemble a nuclear warhead, when a November 2009 article in The Guardian said the allegations included Iran's weapon design activities using two-point implosion designs.
