Islamist Assassins

John McIntyre, in You Don't Say: Language and Usage, arguing that the term "Islamofascism" is inaccurate and misleading, suggests an alternative:

But perhaps a better parallel is with the Hashshash, the Nizari sect or cult of Ismaili Islam that is more familiarly known in the West as the Assassins. Thriving in the 11th to 13th centuries, the Assassins conducted a campaign of terrorism against the Abbasid caliphate in Baghdad and the Fatimid caliphate in Cairo. (You can look it up in Britannica, as I did.) Though they operated out of strongholds, they did not constitute a state; their aim was to unsettle established regimes, and they succeeded in making a great deal of trouble until the Mongols crushed them.

For anyone interested in history rather than cheap and inaccurate rhetorical brickbats, there is a parallel to be drawn with Osama bin Laden that is more compelling than Hitler or Mussolini or Franco.

Not a bad point. And referring to al-Qaeda as a band of assassins seems apt.
