Terror in Colombia as huge mass brawl breaks out, leaving 20 fans injured, during Atletico Nacional's clash with Atletico Junior

Atletico Nacional were leading Atletico Junior 2-0 in the second half of their Prima A clash when fighting rival fans caused the game to be stopped at Atanasio Girardo Stadium. According to the Daily Mail, several of the 20 fans who were harmed were treated in the stands or taken to medical centres nearby; with some at the ground allegedly wielding knives and machetes in the chaos on Thursday.

Manuel Villa, who is Security of Security in the Colombian city of Medellin, said after the game: "Football should be a celebration of peace. The culture of football is a collective commitment. But if someone doesn't understand that, they have no place in this celebration: those masquerading as fans who create these situations and act outside the law are not fans, but criminals and should be treated as such. Irresponsible! There will be sanctions, and measures will be taken as necessary."

This pandemonium and violence leaves a stain on Colombian football. According to reports, footage of the brawls have captured one visiting fan wielding a knife on Nacional supporters, before riot police intervened. Local newspaper El Heraldo reported that stun grenades were used to disperse crowds on a dark day in football.

The stadium was eventually evacuated by police, with a new date for the contest not yet known at this time. Atletico Nacional are next in action on Sunday at home to Boyaca Chico FC.
