Police guard a side street during the “yellow vests” demonstration on the Champs-Elysées near the Arc de Triomphe on December 8, 2018 in Paris France. “Yellow Vests” (“Gilet Jaunes” or “Vestes Jaunes”) is a protest movement without political affiliation which was inspired by opposition to a new fuel tax. After a month of protests, which have wrecked parts of Paris and other French cities, there are fears the movement has been infiltrated by “ultra-violent” protesters. Today's protest has involved at least 5,000 demonstrators gathering in the Parisian city centre with police having made over 200 arrests so far. (Photo by Chris McGrath/Getty Images)
