Neo-nationalist groups have been increasing in number in Russia, and violent clashes in the capital between Muslims and ethnic Slavs have raised concerns authorities will be unable to keep order ahead of March 2012 elections.

After being convicted, some of the nationalists shouted: "Our conscience is above your laws, we'll be back!" Interfax news agency reported.
They were also found guilty of attempted terrorism, creating and participating in extremism and inciting racial hatred.
