Some supporters ignited fireworks and flares behind one of the goalposts, causing the referee to halt play after the first five minutes. The attempts to restart the game were met with similar scenes, and the game was officially abandoned.
“Ajax considers what happened in the stadium this evening to be utterly outrageous,” the Amsterdam club said in a statement on their website.
“We offer our apologies to everyone who has been affected in any way. The safety of spectators and players has been put at risk. That is unacceptable.
“We emphatically distance ourselves from this misconduct. Fireworks do not belong in the stadium.”
The club added that despite security measures in place, they were unable to prevent the incident and will investigate the footage to identify culprits.
“If this leads to the identification of offenders, we will take appropriate measures,” the club said.
Ajax announced the game will now be played on Tuesday behind closed doors. They are currently sixth with 20 points in 13 games in the Dutch league.
