A large number of Muslim Brotherhood ( MB ) affiliates have joined other terrorist organizations which can fulfill their violent ambitions, MB dissident Sameh Eid told Al-Bawaba News Saturday. MB young cadres have fed up with the MB's performance which does not coincide with the political scene developments, Eid added. The Islamic State (IS) terrorist militia fulfills their ambitions through violence against all Arab regimes not the Egyptian in particular. " Those who failed to join IS fought against Egypt's security personnel within Ansar Beit Al-Maqdis militias," he said.
