Riot police fired tear gas on radical members of the Yellow Vests protest movement in the western French city of Nantes on Saturday. Protesters joined the demonstration against pension reform proposed by President Emmanuel Macron.

Footage shows officers charging into the crowd of black-clad protesters who are seen smashing a bus stop and a car wing mirror.

Macron's government is reportedly aiming to introduce a universal pension system, but trade unions say that this will result in millions of private sector workers having to work beyond the legal retirement age in order to get a full pension.

The 'Yellow Vests' protesters who have been holding weekly rallies against Macron across the country have vowed to join the union-led demonstrations.
