(JNS.org) A new report by The Media Line news agency indicates that Iran’s Revolutionary Guard, not Israel, was behind the mysterious deaths of Iranian nuclear scientists in 2007. Since the incident, conspiracy theories have claimed the Jewish state assassinated the scientists. Mahboobeh Hosseinpour – the sister of Iranian nuclear physicist Ardeshir Hosseinpour, who was allegedly “gassed” to death in 2007 – says her brother was murdered by the Revolutionary Guard because he would not cooperate with its efforts to build an atomic bomb.

Hosseinpour, 54, told The Media Line that her sister-in-law, Sara Araghi, went to her husband’s office at Shiraz University and found evidence that the room was searched and that items were missing, including a photo of the scientist with then-Iranian President Mohammed Khatami. Araghi also found a DVD of the late Hosseinpour’s nuclear research, containing formulas for building an atomic bomb 12 times more powerful than the bomb America dropped on Hiroshima.
