Charges could be made if the French authorities send a request for such action to the Russian counterparts and provide evidence to establish the guilt of the individuals involved, the source told RIA Novosti.
"It is not very important that Russia and France have different legislation. Russian citizens are obliged to abide by Russian laws wherever they are. The same responsibility exists under the Criminal Code for crimes committed outside Russia, including beatings, personal injuries or destruction of property. For participating in a riot, for example, [the penalty] is up to eight years in prison," the source said.
Earlier on Wednesday, Russian Foreign Minister Sergei Lavrov said that the behavior of some Russian football fans at the Euro 2016 tournament was unacceptable, however, he also noted that there were some provocations.
