Belgian police are now firing tear gas and water cannons into the crowd of protesters at the presidential plaza. This all stems from anger at the French President Emmanuel Macron and France's high taxes.
Barricades are protecting the offices of other leaders such as Prime Minister Charles Michel.
This all came to a peak Saturday morning.
Protesters dressed in yellow vests are destroying public property. Some are throwing rocks while others are smashing street signs. Fireworks, flares, and other objects are being directed at police.
Brussels police spokeswoman Llse Van de Keere said around 400 protesters are gathered in the area, but about 100 have already been detained.
