French Prime Minister Edouard Philippe has announced plans to punish people who hold unsanctioned protests after seven weeks of anti-government unrest.
His government wants to draft new legislation that will ban troublemakers from protests and clamp down on the wearing of masks at demonstrations.
He said 80,000 members of the security forces would be deployed for the next expected wave of protests.
Protesters smashed down the gates to a government office this weekend.
In other chaotic scenes in Paris, demonstrators fought riot police, and cars and motorbikes were burnt.
