Clashes broke out between supporters of Northern Ireland and French locals in the French city of Nice, who had gathered ahead of the team's opening Euro 2016 clash with Poland. 
Seven people were injured, with one supporter suffering a serious head injury.
The trouble started when hooligans threw a bottle at the Northern Irish fans with their Polish counterparts at a pedestrian precinct which had been turned into an open-air pub. 
The fighting escalated and ended with punches and dozens of bottles being thrown. 
Northern Ireland take on Poland on Sunday before facing Ukraine on June 16 and Germany on June 21.
