Russian Nationalists Blow Up Rails?

This video says that russian Nationalists may be to blame for the recent train attacks. I should note that a video of alleged Russian National Socialists executing two non-Whites, beheading one of them, has leak onto the internet. While I was reading some of the discussion regarding the beheading video, somone said that there is an armed resistance about to take place in Russia against "blacks". In Russia, the term "Blacks" refers to all people of colour, not just Negros.
