Tour de France increases security amid fears of climate change protests and civil unrest

People look at burning tyres blocking a street in Bordeaux during civil unrest and protests following the killing by police of 17-year-old Nahel M in Nanterre on Tuesday

Tour de France organisers plan to increase security around the race and stay vigilant due to a growing double risk of disruption from climate change activists and a threat of growing civil unrest in France.

Race director Christian Prudhomme said that he and his staff are in "constant liaison" with the French government, following three nights of civil unrest and protests across France after the fatal police shooting of a 17-year-old boy Nahel M in the Paris suburb of Nanterre on Tuesday.
