It's all kicking off... Poland and Russia fans in ugly clashes

Russia fans clashed with police and Poland supporters in separate incidents in Warsaw yesterday, shortly before the two teams met last night in an emotionally charged European Championship match. Several people were injured.

Polish supporters were seen attacking Russians, who responded violently. The two sides, made up of dozens of men, lashed out with boots and fists, while flares could be seen exploding in their midst.

Poland and Russia fans were also seen fighting and throwing stones outside the National Stadium, despite a very heavy police presence.
