Around 150 Russian were behind much of the violence that marred the Euro 2016 football match between England and Russia, French prosecutors have said.

Dozens of people were injured, four seriously, in clashes between opposing fans in the lead up and immediately following Saturday’s 1-1 draw in Marseille.

Video footage following the game showed a group of Russian fans climbing over barricades and attacking England fans inside the stadium.

French authorities have arrested 20 people in relation to the violence, and 10 people, including six Britons, face immediate trial, according to Marseille prosecutor Brice Robin.

Uefa has launched an investigation into the violence in Marseille, and has threatened both national teams with expulsion form the tournament if there is further fan violence.

European football’s ruling body has also opened disciplinary proceedings against the Russian Football Union for alleged crowd disturbances, racist behaviour and the setting off of fireworks by its fans during the England vs Russia game.
