Clashes, tear gas and arrests amid multiple demonstrations in Paris

Metro stations were closed and violent clashes with police broke out in Paris on Saturday when a march calling for firm action on climate change was infiltrated by what appeared to be so-called 'black bloc' anarchists, damaging a bank and setting fire to a barricade, following earlier tear gas charges on Yellow Vest demonstrators in the centre of the capital, where trades union members also marched in protest at planned pension reforms.
