Marches in Paris and cities across the country drew hundreds of thousands of protesters and often culminated in tear-gas-laden street battles between truncheon-swinging riot officers and anarchist groups. Nuit Debout, a French version of Occupy Wall Street, drew large gatherings of young people to nighttime meetings in the Place de la République in Paris. C.G.T. activists blocked highway lanes and oil refineries, creating fuel shortages. Labor strikes halted train travel and cut output at nuclear-power plants.
