France has announced tough new measures on “yellow vest” protests as the anti-government demonstrations entered its fourth month over the weekend, marked by clashes with the police, nearly 200 arrests and damage to businesses by some protesters. Police used tear gas and water cannons on crowds in Paris. On Monday, Prime Minister Édouard Philippe banned the yellow vests from the Champs-Élysées and certain neighborhoods, as well as announced the shutdown of any protest that included violent or “ultra-radicalized” groups. Prime Minister Philippe also said the Paris police chief would be replaced and police officers would be granted more autonomy.
