French yellow vest protesters set life-threatening fires, smashed up luxury stores in Paris and clashed with police Saturday in the 18th straight weekend of demonstrations against President Emmanuel Macron. Large plumes of smoke rose above the rioting on Paris? landmark Champs-Elysees avenue. Cobblestones flew in the air and smoke from fires set by protesters mingled with clouds of tear gas sprayed by police, as tensions continued for hours along the Champs-Elysees. By dusk, as the demonstrators had dispersed, the famed avenue was a blackened expanse. Simultaneous fires were also put out from two burning newspaper kiosks, which sent black smoke high into the sky. Several protesters posed for a photo in front of one charred kiosk. Demonstrators also targeted symbols of the luxury industry, smashing and pillaging shops including brands Hugo Boss and Lacoste, and tossing mannequins out of broken windows. A posh eatery called Fouquet?s, which is associated with politicians and celebrities, was vandalized and set on fire. A vehicle burned outside the luxury boutique Kenzo, one of many blazes on and around the Champs-Elysees.
