MARSEILLE: Brice Robin, the chief Marseille prosecutor, has said that 150 Russians were mostly behind the violence which marred and scarred the start of Euro 2016 in the city including at the end of the Russians’ 1-1 draw with England on Saturday night.

Violence erupted at the final whistle as Russian hooligan gangs charged into a section of English supporters and began to attack them.

Robin said that 35 people were injured, mostly English fans. Four he considered as seriously injured.

He also reported that so far 10 people, including six Britons, three French and an Austrian, face an immediate trial. Two Russians had been arrested for invading the pitch at the Stade Velodrome.

Robin echoed claims by English fans in saying: “These people were well prepared for ultra-rapid, ultra-violent action. These are extremely well trained people.”

UEFA has opened an investigation against the Russian Football Union and warned that repeat scenes could bring team expulsions.

Russian Sports Ministry and 2018 World Cup organising officials have made little attempt as yet to distance themselves from the perpetrators.
