Police in Paris have used tear gas to disperse anti-government demonstrators who are trying to revive the yellow vest movement in protest at perceived economic injustice and French President Emmanuel Macron's government.
The French capital was placed under high security on Saturday as a few hundred anti-government protesters started marching in the streets.
Police in riot gear were moving quickly to disperse small crowds of protesters, using tear gas on and around the Champs-Elysees avenue, Saint-Lazare train station and Madeleine plaza - areas where protests have been banned this weekend.
Most demonstrators didn't wear the fluorescent vests that gave the movement its name.
Paris police said at least 106 people were arrested and 1249 security checks took place. Over 100 people received fines for demonstrating in a banned area.
Paris police said no damage was registered.
Authorities have deployed more than 7000 officers and banned protests in a large central area including the presidential palace, government and parliament buildings, the Champs-Elysees, the Eiffel Tower and Notre Dame Cathedral.
Several calls for demonstrations had been issued in the cityl by yellow vest supporters, environmental activists and a far-left workers union.
France's annual heritage weekend, a very popular event with many cultural sites open to the public, is also taking place.
Parisians and tourists were queuing to visit landmark and government buildings, including the presidential palace and Macron's office. The public could only access the Elysee after having pre-registered and passing security checks.
Some other monuments, including the Arc de Triomphe that suffered damage during a yellow vest protest last December, will remain closed to the public so the busy police don't have to deal with it.
Macron made multiple concessions to the movement, including a 10-billion euro ($A16 billion) package of measures to boost purchasing power. But anger is now mounting again over his plans to overhaul France's costly, convoluted pension system.
Climate activists are demonstrating Saturday afternoon in Paris to demand more action from the government and companies to reduce emissions and save the burning Amazon rainforest and the melting Arctic.
The hard-left Workers Force union is also holding a separate march against the retirement reform, amid concerns it will require people to work longer and reduce pensions.
