Protests and public gatherings have been prohibited in Marseille from 12 p.m. to 8 p.m. on Monday, according to an announcement from the Bouches-du-Rhône Police Prefecture shared on social media.

French Prime Minister Sébastien Lecornu has also directed select local officials to enforce partial curfews in affected areas.

"If declaring a state of emergency is deemed necessary, we would do so," Lecornu stated.

The measures follow ongoing riots that broke out in cities nationwide after demonstrations against rising living costs and reduced public services turned destructive, marking some of the most intense violence seen in France in decades.

Although hundreds of thousands joined peaceful marches in numerous cities, smaller groups of agitators set fire to public buildings, looted high-end stores and supermarkets, and assaulted police vehicles along with officers.

In Limoges, the city hall was set on fire; in Marseille, masked demonstrators entered city hall and covered it with graffiti; and in Lyon, protesters burned the local tourist office.
