it was arranged by outsiders(chechens, ingush) but carried out by locals, who, in fact, are not nationalistically but religiously influenced.
but i wonder at something else- how dumb it was. Obviously, what on earth 200 gunmen could achieve attacking the capital of a populous republic under the protection of a 150 mln country. Theoretically it would be easier to arrange explosions.
I am afraid chechens wanted blood, it makes the performance brighter, louder and WAY more complicated for federals to deal with. And for that, they used unemployed, dumb, but trained and brainwashed kabardenian ship, why to waste their own precious kind.
even here, we are spawns in somebody's game, and are merely used to carry across somebody else's points.
