Declaring “we are at war,” President Emmanuel Macron of France prohibited public gatherings of any size, postponed municipal elections and told people to stay in their homes except for essential needs.
His order, which goes into effect on Tuesday, is one of the most stringent anywhere in Europe. Officials said that going out for a walk to get some fresh our [recte: air] would be allowed, but meeting a friend on a street or in a park would be punishable with a fine.
Christophe Castaner, the interior minister, said anyone on a public outing would need to carry a document justifying it, even if only a sworn statement written by that person. He said that 100,000 law enforcement officers would be deployed to enforce the order.
