Cossack militia attacked the Pussy Riot punk group with horsewhips on Wednesday as the group tried to perform under a sign advertising the Sochi Olympics. One Cossack appeared to use pepper spray, another whipped several group members while others ripped off their masks and threw the guitar in a garbage can. Cossacks trace their history in Russia back to the 15th century. Serving in the czarist cavalry, they spearheaded imperial Russia's expansion and were often used as border guards. Under communism, they virtually disappeared, but have since resurfaced, particularly in the south.
Here is a gallery of images from the altercation.
