Dar Babl published, two days ago, a synopsis of a report, which it claimed was sent to President Bush by the State Department (foreign affairs), stating that the Mossad (Israel’s Intelligence Institute) has killed 350 Iraqi nuclear scientist in addition to more than 200 university professors from different scientific specialties. It stated that this was done with the help of the American occupation forces. According to the report, these killings were done after the American forces failed in their attempts to recruit these scientists to work in and for the USA. According to Dar Babl, this measure, which targets about 1000 scientists, was taken because Israel believes that the scientists pose a threat to its security if they remain alive.
Update: A commentator brought my attention to this article (En), published May 2006, with the same information. (Thanks).
