The French capital is set to go into a month-long Covid-19 lockdown as the country fears a third wave.
Some 21 million people in 16 areas of France will be placed under the measures from midnight on Friday, 19 March.
These measures will not be as strict as the previous lockdown, prime minister Jean Castex said, with people allowed to exercise outdoors.
France has recorded more than 35,000 new infections within the past 24 hours.
Mr Castex said a “third wave” of infections in the country was looking increasingly likely.
The situation in Paris is particularly worrying with 1,200 people in intensive care, more than at the peak of the second wave in November, health minister Olivier Véran said.
Government spokesman Gabriel Attal stressed there would be differences with the two earlier lockdowns and said further details would be given of which business could stay open or would have to shut.
People will be allowed to exercise outdoors within 10km (6 miles) of their home and are not allowed to travel to other parts of the country unless they have a valid reason. Those in the affected areas will have to fill out a form to explain why they have left their homes.
France’s nationwide curfew will remain in place. However, it will begin an hour later at 19:00 (18:00 GMT), taking into account the long hours of daylight.
Fears of a third wave come as the French government faces criticism for its slow vaccine rollout.
From Friday, France will resume vaccinating using the AstraZeneca jab following the EMA’s announcement that it was fit for use. Mr Castex said he would be getting the vaccine straight away to prove that it was OK.
A survey conducted just as the suspension was announced found that only 20% of the French have confidence in AstraZeneca.
