The activists protecting Chilean protesters, a mass sit-in in Niger, and more

This week our Observers take us to Chile, where we meet the Primera Linea - a group of people on the front line of violent protests who have taken it upon themselves to protect other protesters. Then in Niger, police brutally broke up a mass sit-in by asylum-seekers who have been ignored for too long.A weekly news show produced with photos, videos and personal accounts from France 24 Observers around the world - all checked by our staff here in Paris.
