France has introduced overnight curfews in Paris and other cities in an effort to contain violent protests. The restrictions took effect during the night, according to the report. A curfew limits movement during set hours and is being used to reduce disorder around demonstrations. The short account did not say how many cities were covered or how long the measures would last. It also did not specify any exemptions or whether the curfews followed a particular night of unrest. Paris was the most prominent location named, but the same approach was being applied in other urban areas.
