Reports from the Stade Velodrome in Marseille said Russian supporters went into England fans' areas of the ground after the final whistle, while terrifying videos on social media suggest the same.
The incident came after a third day of violence in the Mediterranean port city left as many as 20 England fans injured, with reportedly several seriously hurt in bloody clashes between rival fans.
Uefa will launch an investigation into events inside the stadium, while elsewhere Russian striker Artem Dzubya thanked Russian fans for creating a "warm" atmosphere.
Attention has been turned towards World Cup 2018, which takes place in Russia...
But reporters currently in France fear things could get worse during this tournament.
Jamie Vardy's wife was caught in the middle of it, and tweeted about her experience.
