Train Bombed in Russia

"[...] either militants from Russia's North Caucasus region or nationalist extremists, pro-Nazi groups"

are likely to blame.

"I think we can expect the Russian authorities to come up with some names soon, because this attack is politically very embarrassing.

"This is an expensive, high speed train, used by an elite which has been pushing to transfer parts of government functions to St Petersburg. We already have reports of several high-ranking government and local officials among the dead.

"Whoever is responsible, this attack clearly seems aimed not so much at the public, but directly at the ruling class."

Protestant militants from Russia's North Caucasus region would seem like persons of interest.
