The Paris police headquarters said authorities detained 227 people carried out more than 20,500 spot checks.

Police fired tear gas and stun grenades amid tensions at a march of several thousand people from France's Finance Ministry toward the Place de la République plaza in eastern Paris.

The violence contrasted sharply with the peaceful atmosphere at another march through Paris, where demonstrators mourned the Notre-Dame blaze while also keeping up the pressure on President Emmanuel Macron, who is expected to unveil new policies aimed at appeasing the Yellow Vests in a speech on Thursday.

It's the first Yellow Vest demonstration since the fire at Notre-Dame cathedral earlier this week.
