France braces for black Saturday of Yellow Vest protests
Date created :
Shopping, culture and tourist outlets across France are bracing for what is being called a black Saturday of Yellow Vest protests. We look at a so-called "official charter" of the movement's demands circulating on Facebook, plus tweets by high school students staging protests of support for pupils detained by police in the Paris suburb of Mantes-la-Jolie on Thursday. Plus, we listen to the sound of wind on Mars sent by NASA's InSight lander. Prepare to be blown away.
