Yellow vest movement: Paris police fire tear gas at protesters

Police in Paris have fired tear gas on protesters as a fourth weekend of anti-government protests turned violent.

Up to 5,000 demonstrators have gathered in the city centre, and at least 272 people have been arrested.

Some 8,000 officers and 12 armoured vehicles have been deployed in Paris alone, and nearly 90,000 in the country as a whole.

The "yellow vest" movement opposed fuel tax rises but ministers say it's been hijacked by "ultra-violent" protesters.
