These men and women were once hidden from sight, concentrated on a no-man's land on the capital's outskirts, until a police operation in December 2019 scattered them across the city's 18th and 19th districts. Locals are now sick of being caught in the middle. Our colleagues from France 2 report, with FRANCE 24's Nadia Charbit.
