France: climate activist Greta Thunberg joins teens on new day of school protests

French students are taking to the streets for a fourth consecutive week of protests over poor school conditions, including teacher shortages, overcrowded classrooms and deteriorating facilities. Backed by trade unions and university students, the movement has led to school blockades and clashes with police. Swedish activist Greta Thunberg joined a demonstration near Paris, while around 200 schools were reported closed amid the mobilisation. FRANCE 24's Clovis Casali has the latest from the ground.
