French authorities enforced curfews on Saturday as they tried to contain widespread disorder. Rioters clashed with police in cities across the country, while also setting cars on fire and storming public buildings. A historic city hall was engulfed in flames during the unrest. Police made at least 2,400 arrests as officials cracked down on those involved in the violence. In Paris, police enforcement of the curfews was presented as a way to restore calm after a day of confrontations. The scale of the arrests and damage showed that the disturbances had reached well beyond the capital.
