SHOCKING video of Russia fans fighting England fans at Euro 2016

The Euro 2016 kicked off last week to much fan fare in France, however it's the violence off the field among the Russian and English supporters has put a dampner on the football event.
In Marseille, England's opening game against Russia was marred with tear gas, fist fights as both sets of supporters clashed outside of the stadium while unsuspecting England fans came under attack inside the Stade Velodrome.
A few of the Russians involved in the violence have now uploaded disturbing footage of the horrifying clashes on the streets of Marseille shot from a Go-Pro video by one of the attackers. 
"Officers separated groups of English and Russian supporters," a police source told Reuters. "They fired tear gas to disperse some drunk Englishmen." The video shows an almost military like operation launched by the Russiand fans in an attempt to injure England fans.
At one point in the video, an English supporter is seen lying unconscious while the mob of Russians mercilessly kick and beat him up. The video also shows some wielding cafe tables and glass bottles as weapons, along the narrow streets leading off Marseille's old port.
