Journalist Bryn Lucas has told of his experiences witnessing violence both inside and outside the Stade Vélodrome in Marseille on Saturday.
“I was in a bar before the match, and there was a huge scuffle," he told Paul Ross.
"There were four Russian guys with gum shields in, and they just ran straight at the English fans in the bar and started punching them. It was shocking to the core."
Lucas said that inside the stadium, the atmosphere was initially “fantastic”.
“But as soon as the [Russia] goal was scored, it turned into pandemonium. We didn’t really understand what was going on.
"You just saw English fans running as fast as they could away from the onrushing Russian fans.
“These people just arrived from nowhere and starting punching them, gesturing, trying to encourage a confrontation.
“You saw them jumping across and trying to get out where the tunnel was – a drop of about 10 or 15 feet.
“The bonus for us was there was no retaliation, the English fans were very much trying to get away.”
Numerous English fans were injured, and one has been left fighting for his life after the trouble.
The UEFA executive committee has expressed "disgust" at the clashes which have marred the tournament thus far.
