Max Fisher writes: Last week, the United States and several Arab allies began bombing ISIS targets in Syria — as well as a mysterious and little-known faction of al-Qaeda that the US says is called Khorasan.

The group’s name, like much else about it, is the subject of some uncertainty and debate. Some have suggested that the US made up the name, perhaps derived from internal al-Qaeda communication referring to the militants as something perhaps like “Our brothers from Khorasan.”

But it turns out that the group may refer to itself by a very different name: the Wolf Unit of Jabhat al-Nusra. That’s according to some apparently internal documents uncovered by Jenan Moussa, a highly respected reporter with the Dubai-based outlet Al Aan TV.

Moussa found the documents in the rubble of a house the group used in the Syrian city of Aleppo and that had been bombed in the US-led airstrikes. (She is braver than you are.) A list of names identifies 13 men, one of them identified by the US as a Khorasan member, under the heading “Wolf Unit of Jabhat al-Nusra.” Moussa says the name appears to include four Turks, two Egyptians, two Yemenis, two Tunisians, one Palestinian, one Serbian, and one from the Caucasus region.

The following video features in Moussa’s Al Aan TV report. She says: “One video of the Wolves exist online.”

The video was uploaded a week ago on an account with the name “Ribat Medya” but after having had 16,600 views, YouTube removed it: “This video has been removed because its content violated YouTube’s Terms of Service.” Obviously, Jabhat al-Nusra weren’t complaining about copyright infringement and there’s nothing offensive in the content (unless one is offended by the sight of members of al Qaeda performing conventional military exercises in a forest, presumably somewhere in Syria). Is YouTube following directions from the Pentagon to censor videos for political reasons?
