French officials say they have placed 43 Russian soccer fans in police custody on suspicion of being involved in clashes during the Euro 2016 tournament.
The Russians were in a bus in southern France heading for their country's next match in the northern city of Lille.
Government official Adolphe Colrat said on June 14 that prosecutors believe they have "sufficiently accurate information" that some of them took part in last week's violence in Marseille.
Meanwhile, Aleksandr Shprygin, head of the Russian Union of Supporters, said 29 supporters were being deported from France, adding they had "violated no laws in France."
Russian fans clashed with English team supporters before the two countries' June 11 match.
When the game ended in a 1-1 draw, Russian supporters attacked English fans in the stadium in fighting that continued in the city afterward.
At least 35 people -- mostly Britons -- were injured in the clashes.
French officials said some 150 Russians involved in the attacks were "extremely well-trained" and prepared for "ultraviolent action."
Six Britons were jailed on June 12 for their roles in the disorder, and European soccer's governing body, UEFA, has threatened to disqualify both teams if there is further violence.
Earlier on June 14, UEFA gave Russia a fine and "suspended disqualification" that would go into effect if "incidents of a similar nature happen inside the stadium" at any of Russia's remaining games.
