French president Emmanuel Macron will lead an urgent security meeting on Sunday, following a day of riots by hundreds of anti-government protesters in Paris, reports the BBC.
A government spokesperson said a state of emergency could be imposed to tackle the unrest.
Protests over fuel tax have grown into general anger at higher living costs.
While some demonstrators have remained peaceful, others clashed violently with police and scaled the Arc de Triomphe.
More than 100 people were injured, including 23 members of the security forces, on Saturday.
Police say more than 400 people were arrested.
Mr Macron returned from the G20 summit in Argentina on Sunday morning and went straight to the Arc de Triomphe to assess the damage.
