Alimohammadi, a Tehran University physics professor, was slain in January 2010 by a booby-trapped motorcycle parked next to his car just as he left for work in the morning.
It’s one of a whole pattern of “events that happen unnaturally” befalling Iranian scientists — events whose rather self-evident foreign sponsorship is supposed to be bracketed as “alleged” and definitely not described as “terrorism”.
Whether that’s specifically true in Alimohammadi’s case is arguably a bit harder to judge, since he was not directly involved in Iran’s nuclear program. Iran’s western opponents have speculated that Tehran itself murdered him because he was a (low-key) supporter of the country’s opposition who in death could serve as an official martyr.
That would be awfully convenient: official martyrs come cheap but Iran doesn’t exactly have a limitless supply of particle physicists.
Accurately or not, Fashi confessed to carrying out Alimohammadi’s assassination, claiming that he was recruited, paid, and trained by the Mossad for the job.
