Police and protesters clashed in the streets of Brussels on Sunday in demonstrations over government-imposed COVID-19 restrictions, with police firing water cannon and tear gas at demonstrators throwing rocks and smoke bombs, witnesses said, Trend reports citing Reuters.
About 35,000 people took part in demonstrations, police said, which began peacefully before violence broke out.
Protesters wearing black hoods threw stones at police as they advanced with water cannon at the main junction in front of the European Union Commission headquarters, Reuters journalists said.
Facing up to the police lines, the protesters held hands and chanted "freedom". One protester was carrying a placard reading "when tyranny becomes law, rebellion becomes duty".
Protesters also threw smoke bombs and fireworks, the newspaper Le Soir reported. The situation calmed down later, police said.
