A university professor was killed by a bomb placed on his car by a motorcyclist in Tehran on Wednesday, Iranian media reported, in an incident that looked similar to attacks on nuclear scientists in the city more than one year ago.

The semi-official Fars news agency cited witnesses as saying a motorcyclist stuck a bomb on the side of the car which then exploded, killing one and injuring two people inside. Fars identified the victim as Mostafa Ahmadi-Roshan. State-run Press TV said he was a university professor.
