A second man who was severely injured in today's terrorist blast in a Northern Tehran neighborhood died of his wounds in hospital.
The blast on Wednesday morning targeted Mostafa Ahmadi Roshan Behdast, an Iranian university professor and deputy director at Natanz enrichment facility.
The second victim, Reza Qashqayee, who was the driver of the assassinated professor, was severely injured in the blast and died of his wounds in Resalat Hospital a few minutes ago.
The magnetic bomb which was planted by an unknown motorcyclist under Ahmadi Roshan's car, also wounded a third person, a passerby, in Seyed Khandan neighborhood in Northern Tehran.
Ahmadi Roshan Behdast, 32, had majored in chemistry at the Oil Industry University and was a deputy director for commerce at Natanz uranium enrichment facility.
Today's blast took place on the second anniversary of the martyrdom of Iranian university professor and nuclear scientist, Massoud Ali Mohammadi, who was also assassinated in a terrorist bomb attack in Tehran on January 11, 2010.
Also, the bombing method used against Ahmadi Roshan Behdast this morning was similar to the 2010 terrorist bomb attacks against the then university professor, Fereidoun Abbassi Davani - who is now the head of Iran's Atomic Energy Organization - and his colleague Majid Shahriari.
