Dec 1 (Reuters) - Ajax have condemned the fireworks display by supporters at the Johan Cruyff Arena that resulted in the Eredivisie game against Groningen being called off on Sunday, saying they will take action against the perpetrators.

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.
