The seats are on fire

The 137th Eternal Derby between Red Star Belgrade and Partizan Belgrade was a scene of overwhelming madness as the fire hoses had to be called in to make an attempt at controlling the blazes in the stands (and the shirtless guy in the bucket hat).

Things weren't any more tame on the pitch, though between what appeared to be an angry makeout session (0:53 into the video below) and players stomping on each other (1:20).
