Shocking video: Cossack militia attacks Pussy Riot with whips at Sochi Olympics

SOCHI, Russia - Cossack militia have attacked the Pussy Riot punk group with whips and violently removed members' trademark ski masks in the Olympic host city, all captured on video.

The group had gathered in a downtown Sochi restaurant on Wednesday, about 21 miles (30km) from the Winter Olympics site. They ran out of the restaurant wearing brightly colored clothes and ski masks and were set upon by about a dozen Cossacks, who are used by police authorities to patrol the streets.

The group tried to start performing, but a Cossack smashed their guitar. The incident lasted less than five minutes and one Pussy Riot member, a man, was left with blood on his face, saying he was pushed to the ground. Police arrived and questioned witnesses. No one was arrested.
