Iranian media reported Wednesday that a university professor and nuclear scientist was killed by a bomb placed on his car by a motorcyclist in Tehran.
According to the semi-official Fars news agency, Mostafa Ahmadi Roshan, 32, supervised a department at Natanz uranium enrichment facility in Isfahan province.
Fars cited witnesses as saying a motorcyclist stuck a magnetic bomb on the side of the car which then exploded, killing one and wounding two people inside. Fars identified the victim as Mostafa Ahmadi-Roshan.
Deputy Governor Safarali Baratloo blamed Israel for the bombing, saying it was similar to ones targeting nuclear scientists a year ago.
"The bomb was a magnetic one and the same as the ones previously used for the assassination of the scientists, and is the work of the Zionists [Israelis]" Fars quoted Baratloo as saying.
The attack coincided with the second anniversary of a explosion that killed senior Iranian nuclear scientist Majid Shahriari.
Several Iranian nuclear scientists have been assassinated in recent years. Tehran has blamed the killings on Israel and the U.S. Both countries deny the accusations.
