(Newser) – One prominent nuclear scientist was killed and another wounded in separate attacks in Tehran today. Majid Shahriari, a member of the nuclear-engineering faculty at Tehran University, was killed when an attacker on a motorcycle attached a bomb to his car, AP reports. His colleague was injured in an identical attack in another part of Tehran.



Another Iranian nuclear professor was killed earlier this year when a motorcycle rigged with explosives was detonated outside his home. Iranian authorities, who claim Western governments seeking to thwart the country's nuclear ambitions are behind the attacks on nuclear scientists, issued a statement blaming today's attacks on "Zionist agents" and vowing revenge.
