People took to the streets across France on Saturday after President Emmanuel Macron imposed an unpopular pension overhaul without a parliament vote.
Macron's government on Thursday invoked a controversial executive power to force through the bill by decree, which is legal according to the constitution.
The move has caused outrage among the political class as well as angry protests on the streets, presenting the 45-year-old leader with one of his biggest challenges less than a year into his second and final mandate.
The president has made no public comments since the bill to raise the retirement age from 62 to 64 was forced through.
A source within his circle however told AFP on Saturday evening that he was "following developments".
Police on Saturday banned gatherings on a key Paris square opposite parliament after two nights of unrest at the site.
But thousands of protesters rallied in another part of the capital, some erecting barricades in the street, setting rubbish bins on fire and smashing advertising boards, an AFP journalist saw.
Security forces charged at the demonstrators and fired tear gas and water cannon at Place d'Italie. A police source said officers had arrested 81 people at or near the location.
No-confidence vote
In parliament, opposition lawmakers have filed two motions of no confidence in the government, which are to be debated on Monday afternoon according to parliamentary sources.
They hope to garner enough support to topple the government and repeal the law.
But Prime Minister Elisabeth Borne's government is largely expected to survive any no-confidence vote.
The motion would need backing from around half the group of opposition right-wing Republicans, a scenario seen as highly improbable.
Saturday's protests follow two previous nights of unrest.
Thousands of people rallied in Place de la Concorde opposite parliament on Friday evening to vent their frustration.
Groups of people threw bottles and fireworks at the security forces, who responded by firing tear gas to try to clear the square. Police said they made 61 arrests.
In the eastern city of Lyon, demonstrators tried to break into a town hall and set fire to the building, said police, who reported 36 arrests.
