England and Wales fans appear to have been caught up in violent clashes with Russian fans in video footage posted on social media.
Mobile phone video posted on Twitter showed two sets of fans facing off outside a bar, with chairs strewn across the pavement on the Place de la Gare, in central Lille.
A group of people, some wearing football shirts, could be heard chanting "We're England and Wales, f*** off Russia" as police and security staff tried to calm the situation.
The footage shows a man in a suit shouting "allez", French for "go", to hooded and masked fans posturing towards the England and Wales supporters outside Le Palais de la Biere bar next to the city's Hotel Continental.
He attempts to set chairs and tables right again before police officers move in between the two groups of fans.
Members of the public could also be seen gathering and taking photos of the melee.
