Watch | Soccer fans engage in a massive brawl

Violence broke out between supporters of rival teams during a soccer match some 1,700 kilometres north of Rio de Janeiro. Dozens of angry fans from both teams invaded the pitch to attack one another, as well as players and officials. One man was unconscious on the ground as he was kicked by more than 10 fans. Brazil is notorious for football violence with incidents taking place inside stadia and deaths occurring outside grounds every year.
