You guessed it, it was more Misunderstanders of Islam -- the "Caucasian Mujahadeen," which of course means they're from the Caucasus, not that they're white (although they are). If opposition to jihad is white supremacist, shouldn't the "Caucasian Mujahadeen" be just fine with anti-jihadists?
"North Caucasus group in Russia train bomb web claim," from the BBC, December 2 (thanks to Alan of England):
A North Caucasus Islamist group has claimed responsibility for a bomb that killed 26 people on a Moscow-to-St Petersburg train, a website says.
The website claim on Kavkazcenter.com said last Friday's attack was carried out by the "Caucasian Mujahadeen" on the orders of its leader, Doku Umarov.
He is described as one of Russia's most wanted rebels, but it was not possible to verify the claim's authenticity.
Moscow had earlier described the Nevsky Express attack as an act of terrorism.
Doku Umarov, a Chechen, is considered the leader of the Islamist insurgency in the North Caucasus. He says he is fighting to expel Russian forces, and to turn the region into an Islamic emirate.
Wednesday's web statement said Friday's attack was an "act of sabotage", and part of a series of operations targeting strategic sites in Russia.
"Today, we carry out sabotage operations on electricity transmission lines, oil-and-gas-wires. Many of the operations are under preparation status.
"We intend to conduct such diversions in future, which are the just acts of vengeance... These diversions will continue for as long as the occupants in the Caucasus will not stop its policy of killing ordinary Muslims purely on religious grounds."...
