A nuclear physics professor who publicly backed Iranian opposition leader Mir Hossein Mousavi in the disputed June presidential election was killed Tuesday when a remote-controlled bomb rigged to a motorcycle blew up outside his home.

State media identified the victim as Masoud Ali Mohammadi, 50, a professor at Tehran University, which has been at the center of recent protests by student opposition supporters. Before the election, pro-reform Web sites published Ali Mohammadi’s name among a list of 240 Tehran University teachers who supported Mousavi.

And of course, despite the public call for the assassination of opposition voices by the Iranian leadership, three guesses who they’re blaming for this one. Don’t need three? Got it in one? Yeah, I thought so:

The government blamed the rare assassination on an armed Iranian opposition group that it said operated under the direction of Israel and the U.S.

Cause, like, sure, that makes sense. Then again, when has logic ever been a factor in cases like these?
