French protestors have rallied for the seventh time since January 2020 to oppose President Emmanuel Macron's plan to raise the retirement age.
Demonstrators have frequently been bolstered by strikes in sectors such as transport, energy and waste collection.
There were ongoing debates in parliament with a final vote expected soon.
Police clashes occurred in Paris as some demonstrators dressed in black destroyed urban equipment and set fires to piles of trash along the route of the march.
While union groups claim more than a million protestors attended, the French Interior Ministry estimated that 368,000 people took part.
Macron declined to meet with union leaders twice in the past week to discuss their concerns.
Opponents of French President Emmanuel Macron's plan to raise the retirement age from 62 to 64 have taken to the streets for a seventh day of protests.
Demonstrations have been characterised by ongoing strikes from various sectors, including energy, transport and waste collection.
While determination has remained high, crowds have notably decreased in size from previous protests.
Estimates of attendance ranged from 368,000 according to the French Interior Ministry to more than one million according to the union CGT.
The bill is now moving towards a final vote in the National Assembly and the Senate, with rallies and events aimed at pressuring Macron to reconsider the policy.
Union leaders have called for Macron to engage in discussion, with a spokesperson for the CFDT union stating that "the endgame is now.
" Macron, however, has twice turned down urgent calls to meet and discuss grievances, prompting criticism from union boss Philippe Martinez who stated "when there are millions of people in the streets, when there are strikes and all we get from the other side is silence, people wonder: What more do we need to do to be heard?
" Police staged several notable clashes with trouble-makers in several cities, including Paris, who destroyed urban infrastructure and set fire to piles of waste along the route of the march.
