Video: Fans launch amazing toilet paper waterfall onto football pitch
In an apparently organised stunt, a spectacular waterfall of toilet paper descended from the home stands in Maurice Dufrasne Stadium shortly before kickoff.
The rippling wall of white paper covered the ground surrounding one goal on the pitch.
Sunday's game, between Belgian football teams Standard Liege and Anderlecht, had to be delayed while ground staff cleaned up the mess.
Standard Liege were undeterred by the interruption and went on to beat Anderlecht 1-0.
