About one in three people in France, with a population of nearly 67 million, will be affected by tougher regional measures in place for the next four weeks to slow the spread of coronavirus.
Four weeks is the amount of time needed to have an effect, said Prime Minister Jean Castex on Thursday regarding the measures set to enter effect from Saturday in 16 areas, including the Paris metropolitan area.
As part of the measures, all non-essential shops must close, though bookshops and music shops are allowed to stay open. Schools can also remain open, but there are restrictions on the upper grades.
The coronavirus situation has deteriorated significantly in Paris and other areas recently, with patients transferred to hospitals in other parts of France due to lack of capacity at intensive care units.
Over 91,000 people have died from coronavirus-related causes in the country so far.
