PARIS, FRANCE - DECEMBER 08: A protester takes a video call on his phone as he throws a tear gas canister back at police during the 'yellow vests' demonstration 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)
