'Drone Melee' Halts Serbia-Albania Euro 2016 Qualifying Match

Serbian emotions were high, with fans burning a NATO flag in the stands during the action. As a precaution, no Albanian fans had been allowed to attend the match.

The teams played through one stoppage and nearly 40 minutes of scoreless football until flares thrown toward the Albanian players interrupted play.

Then a seemingly remote-controlled drone appeared from the stands area, with a flag attached, before dropping low above the field on the Serbian side.

As it approached the field, it became clear that a flag was bearing a "Greater Albania" emblem -- a notion that would extend to Kosovo.

After the drone swooped very low over the players, Serbian defender Stefan Mitrovic leaped up and ripped the flag down.

Mitrovic was immediately confronted by Albanian players, one of whom pulled the flag away, as scuffles broke out and players, team officials, and fans stormed out onto the field.

The scuffles grew more intense, and the local crowd reacted angrily...

...with some team officials and fans breaking through security and managing to approach and attack Albanian players.

After about a minute of dangerous chaos and the crowd seemingly at fever pitch but the worst of the violence seemingly over, the Albanian team broke for the tunnel.

Albanian team officials reportedly told English referee Martin Atkinson that they were in neither any physical nor psychological state to play after the melee.

Serbian riot police clashed with the fans during the match...

...and with the Partizan melee in the books, UEFA has said it will take a long, hard look at the incident and is likely to dole out punishment.

It was initially unclear who was responsible for the drone-and-flag that taunted the players and dove down near the field, but early unconfirmed reports in Serbian media blamed a brother of Albania's prime minister.
