Infolive.tv - Israel News - Israel was behind the assassination of the Iranian nuclear scientist last week in Tehran, the German Der Spiegel magazine reported. The article claimed it was the first major operation of the new Mossad director Tamir Pardo and surveys a series of assassination attempts of Iranian nuclear scientisits in the past 18 months. The newspaper claims the victim was involved in the development of switches for a nuclear bomb and had worked in a research center in northern Tehran. It pointed out that following the scientist's death there were conflicting reports concerning his identity. Initially he was identified as Darioush Rezaei a physics professor and expert in neutron transport but later Iranian authorities identified him as Darioush Rezaeinejad an electronics student. The German newspaper insists the victim was Professor Rezaei who has not been seen in public since the incident. The intelligence sources told Der Spiegel that the Israeli Air Force support launching an aerial attack on Iran's nuclear sites, a plan the Mossad opposes. As long as the Mossad is leading the campaign against the Iranian nuclear program it continues to get the big targets, the source said.
