BLOODY CLASH OF FANS: Unprecedented chaos over a mural - one person is in life-threatening condition! (VIDEO)

About 50 fans took part in the brutal fight, and because of the incidents they committed, the police had to react.

Batons and pyrotechnic devices were used, and the conflict between the two warring fan groups arose around a mural. Zrinjski's fans wanted to draw graffiti on one of the walls that were previously "picked up" by Velež's fans, so there was a conflict between the ardent fans of the city's rivals.

Even two police officers who were trying to stop the conflict on the city streets were injured during the intervention.

One young fan had the worst experience as he sustained severe bodily injuries. He was transferred to the University Clinical Hospital of Mostar, where doctors are fighting for his life, and photos and footage from the scene show that there a lot of blood was spilled during the conflict.
