If it, for instance, if it was hydrogen peroxide, sort of a signature of al Qaeda. If it was more conventional explosives, which are much harder to get hold of now, it might be some other kind of right wing extremists...

To the Left, if you’re not explicitly leftist, then you are “right wing”. So al queda are right-wing extremists.
That could very easily be the fault of bad grammar.
