 The fifth killing was of Mohammad Massoud, a maverick newspaper editor and opponent of the regime.Roozbeh thought that "the assassination of such a popular anticourt journalist ... would polarize Iran and thus radicalize the Tudeh," and emphasized that he carried out the Massoud assassination without the party's knowledge.In the words of Ervand Abrahamian, "Roozbeh was a radical in the tradition of Bakhunin — not of Marx and Engels."
