An Iranian nuclear physics professor who publicly backed Iranian opposition leader Mir Hossein Mousavi has been killed just outside his home. Massoud Ali Mohammadi was on his way to work when a remote-controlled bomb ripped through northern the Qeytariyeh neighbourhood where he lived. Ali Mohammadi reportedly had no involvement in Iran’s controversial atomic energy program, which has long been suspected of developing nuclear weapons. Officials at Tehran University where Ali Mohammadi worked, and at Iran’s nuclear agency, say that his work was primarily in quantum and theoretical physics. A spokesperson for the Iranian foreign ministry blamed “the vices of the Zionist regime, the U.S. and their mercenaries in Iran” for the deadly attack.
