A university lecturer and nuclear scientist has been killed in a car explosion in north Tehran, reports say.
Iranian media sources named the casualty as Mostafa Ahmadi-Roshan, Reuters news agency reports.
The blast happened when a motorcyclist stuck a bomb on the side of the car, says Iran’s semi-official Fars news agency.
Local sources said the blast took place at a faculty of Iran’s Allameh Tabatai university.
Two others were reportedly also injured in the blast, which took place near Gol Nabi Street, in the north of the capital.
Mr Ahmadi-Roshan, 32, was a graduate of oil industry university and supervised a department at Natanz uranium enrichment facility in Isfahan province, Fars reported.
Several Iranian nuclear scientists have been assassinated in recent years. Tehran has blamed the killings on Israel and the US. Both countries deny the accusations.
