About 150 specially trained football hooligans came to France from Russia to take part in the riots.
According to Associated Press, this was told by the prosecutor of Marceille Brice Robin.
Robin also said that “despite the fact that almost all the victims [of fan clashes] were British”, British fans were also responsible for some of the riots. According to the prosecutor, a total of 20 people are currently under arrest.
Clashes between Russian and British fans began in Marseille on June 10, on the eve of the game between the two teams during the Euro-2016. On the day of the match, they continued in the city and in the stadium. In total, about 35 people were injured, some of them are in serious condition.
UEFA demanded from English and Russian football federations to influence the fans, promising that serious measures will be taken otherwise, up to disqualification the teams from the tournament. Also, disciplinary proceedings were opened against Russia due to the behavior of the fans in the stands.
The match, held on the evening of June 11 ended with the score 1:1.
