Paris (CNN) Violent clashes broke out between riot police and protesters in Paris on Saturday, after "gilets jaunes," or yellow vest protesters, as well as anti-capitalist activists joined a climate change demonstration.

Police used tear gas, shields and truncheons as they pushed back the protest, which included Black Bloc activists -- anti-capitalist protesters dressed in black, some with their faces covered by masks -- and some gilets jaunes in addition to environmental activists.

Riot police hit protesters with truncheons, while a pile of burning motorcycles billowed plumes of black smoke into the sky. A bank and an estate agent had their front windows smashed.

Police walk through a tear gas cloud on the Champs-Élysées Saturday.

The "March for Climate" protest was organised by NGOs and Greenpeace. In a tweet following the clashes between police and demonstrators, Greenpeace France asked climate change protesters to leave as "conditions for a non-violent march are not met."

Earlier on Saturday, a large police presence was deployed to disperse the gilets jaunes from the Champs-Élysées, the luxury shopping street in central Paris.
