Ajax supporters expressed their frustration on Sunday in Amsterdam after some of their matches were postponed due to police strikes.

The situation escalated as fans ignited flares, vandalized buildings, and clashed with law enforcement following a demonstration.

Local media captured images of Ajax fans seizing bicycles and barriers while advancing towards the police headquarters, prompting a response from officers to restore order.

Amsterdam police issued a statement on X, indicating, "The situation is unstable at the police HQ in Amsterdam. Ajax fans are vandalizing the building and police vehicles."

They noted that despite multiple warnings, a group of fans persisted in seeking confrontation, leading the elite riot police to take action to disperse them.

Earlier that day, fans had gathered to protest the scheduling of three matches coinciding with police strikes related to pension issues.

Authorities determined that the "Klassieker" match between Ajax and Feyenoord could not proceed without police presence, resulting in the postponement of Sunday’s match against Utrecht. However, another match against NAC Breda was played despite the absence of police due to the strike.

The F-side supporters’ group expressed their dissatisfaction, stating that fans are "completely fed up that Ajax games are continuously the target of this sort of police action."

Ajax is frustrated with being three matches behind in the championship, with rescheduled games occurring at inconvenient times.

The club is eager to recover from a disappointing previous season that saw them at the bottom of the Eredivisie table at one point. So far, they have achieved one win and one loss in their two matches this season.

Police have denied any intentional targeting of Ajax, noting that officers were also on strike during a significant climate demonstration in The Hague on Saturday.
