"The thugs and the black blocs come to sow chaos, disorder (...) They come to disrupt the demonstration," says the prefect of police of Paris. 11,000 police and gendarmes will be deployed, including 4,000 in Paris, according to police sources.

Some 250 actions are planned in France, which should bring together 400,000 to 600,000 people, including 40,000-70,000 radicals, police say. "There is the freedom to protest (...) it is complicated to prevent them from coming to demonstrate, " says the police prefect.
