Authorities in Paris have declared a curfew in selected neighborhoods for a second consecutive night. The restriction is designed to improve public safety and create a calmer atmosphere, according to officials. It applies to parts of the city rather than every district, limiting the measure geographically. The renewed order follows an earlier night of comparable restrictions and signals that officials still see a need for targeted intervention. The announcement did not specify the hours or explain how the restriction would be enforced. Local authorities said the measure had helped maintain order during the previous night. Its effect on residents and local businesses was not yet clear.
