Protesters block the Champs Elysées on Saturday during a demonstration against rising oil prices and living costs.
Police in Paris have fired tear gas and used water cannon against protesters on the Champs Elysées, in the center of the French capital.
The "yellow vest" protests, which began as a campaign against rising gas prices, have morphed into a wider demonstration against the government of President Emmanuel Macron in recent weeks.
Police say they have mobilized 3,000 officers in Paris to deal with the situation. A security perimeter has been set up in the city center, with government buildings protected.
At a news conference on Friday evening, French Interior Minister Christophe Castaner said of the protesters: "Their freedom of expression will be guaranteed, but it must not be exercised to the detriment of security, public order and the right of everybody to come and go. There is no liberty without public order."
