(CNN) -- Ethnic tensions in the Balkans and an incident involving a drone led to the abandonment of a major European international football game Tuesday. Serbia's European Championship qualifying match with Albania was abandoned after 41 minutes following ugly clashes between both sets of players. The brawl followed the arrival of a mini-drone, which flew over the stadium while carrying a flag depicting the "Greater Albania." When Serbian player Stefan Mitrovic ripped the flag down, it provided the catalyst for an already combustible tie to fully ignite. Martin Atkinson, the English referee, took the players off the field with the game goalless following clashes between rival players.
