UEFA has warned the football associations of England and Russia that they could be kicked out of Euro 2016 over fan behavior if there is further violence.
The European football body issued a statement after appalling scenes of violence inside the Stade Velodrome marred the end of the one-one draw between England and Russia on Saturday.
So far a number of arrests have been made in Marseille, while one England fan was reported to be in a critical condition after being attacked.
Disturbances haven't been restricted to Marseille either.
Clashes also erupted along the Mediterranean coast in Nice on Sunday after trouble involving fans from Poland and Northern Ireland.
There have also been reports of violence between 'far-right' fans of Germany and Ukraine in Lille.
