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.
