Wearing a face mask in busy outdoor parts of Paris is mandatory from Monday morning as the country records a flare-up in COVID-19 cases.
Multiple streets, markets, as well as river banks and the famous hill of Montmartre are affected by the new decree.
The Paris town hall said in a statement that the measure was introduced because "the virus is again circulating more actively" in the Ile-de-France region with "nearly 400 people testing positive for COVID-19 every day."
"The rate of positive tests now stands at 2.4% in Ile-de-France against 1.6% on the national average," it also said, adding that "the incidence is particularly high in 20-30 year olds."
