Yellow vest' protests turned violent as demonstrators marched on the streets of the Belgian capital.
Police fired tear gas and water cannons at protesters who tried to gain access to blockaded areas housing European institutions, including the offices of the European Commission and the European Parliament.
Around 450 protesters were reportedly detained so far.
Protesters seemed to have been inspired by similar 'yellow vest' protests upsetting cities across France in recent weeks.
The Yellow Vest movement emerged last month after French President Emmanuel Macron announced controversial hikes in fuel prices to encourage a transition towards greener energy. The French government have now suspended the prices hikes but the protests have nevertheless continued.
