In a statement on Saturday, Ansarullah’s Political Bureau added that martyrdom of such a high-profile scientist was a loss to the entire Muslim world.
Lebanese Hezbollah resistance movement also strongly condemned the terror act.
“We condemn this heinous attack and see that the response to this crime is in the hands of those concerned in Iran,” Hezbollah’s second-in-command Sheikh Naim Qassem said.
Fakhrizadeh was assassinated by unknown gunmen in a small city east of Tehran on Friday evening.
