Offensive banner on a friendly match

Couple of days ago finished all preparatory games for the World Cup which is starting in three months time. Usually, in almost every stadium we can expect rude banners and offensive words which happened on one friendly match.
This Tuesday night, Montenegro and Turkey, who did not qualify for the main football event in June, played an entertaining 90 minutes with 4 goals. As players showed an interesting match on the pitch, on the stands was spotted one insulting banner. Group of supporters from Niksic who gathered in the south tribune spread 'F**k NATO pact' as a result of anniversary of the aggression on Federal Republic of Yugoslavia from the alliance, and that content was quickly shared on social media. Also, there was a flag of Anagastum (which is the oldest name of the town dated from fifth century).
