Brussels police deploy water cannons as masked rioters clash during anti-austerity march

On Friday in Brussels, the boundary between organized protest and street violence fractured into chaos. Hundreds of demonstrators gathered for a union-led march against the government's austerity plans, but as the afternoon wore on, masked figures dressed in black broke away from the main crowd and turned the streets into a battleground. They hurled rocks and bottles at police, smashed windows of two buses after forcing passengers to evacuate, ripped out seats, and set fires to trash cans, rental bicycles, and scooters. The scale was substantial—between 30,000 and 50,000 people had come to march—but the violence was concentrated among a smaller, more militant contingent.

Police responded with water cannons and tear gas after what they described as young people at the protest's edges attacking officers with sticks and bottles. In a statement, authorities said "several hundred youths gathered along with the demonstrators" and that "the atmosphere gradually became more tense and there were serious disturbances to public order." Firefighters moved through the city extinguishing multiple fires. By the end of the day, police had arrested approximately 20 people, most of them minors. The main trade union march itself proceeded without incident, a fact that union leadership had explicitly called for beforehand. Bert Engelaar, the union head, had posted on Facebook urging rioters to stay away, writing that "those individuals have nothing to do with the message with which thousands of others come out on the streets."

The protest was one of many nationwide demonstrations against Belgium's fiscal crisis. The country carries substantial public debt and a persistent budget deficit, and Prime Minister Bart De Wever's center-right government has committed to finding €10 billion in savings—roughly $11.2 billion—by the end of its term in 2029. This is where the political fault line runs. The government's approach leans toward cuts in areas like health services and increases to the value-added tax. The unions are pushing back hard, demanding instead that the government raise taxes on the highest earners. That disagreement, fundamental and unresolved, is what brought tens of thousands to the streets.

The Brussels clashes did not emerge in isolation. A week earlier, in the city of Liege, similar confrontations had erupted when students clashed with police and vandalized shops. Authorities responded by banning public gatherings in that city. Over 200 people were arrested in Liege, and dozens of police officers sustained injuries. The pattern suggests that as the government's austerity agenda moves forward, the street-level resistance is becoming more volatile, and the state's response more restrictive. What began as a union march against budget cuts has become, at least in pockets of the country, a recurring cycle of confrontation.
