A BBC investigation has found one of Europe's most powerful drug gangs in France is recruiting teenage children from across the country to commit kidnap and murder.
Known as the "DZ Mafia", the gang won a bloody turf war against a rival group in Marseille during 2023, and is now recruiting from further afield.
One member who is in prison awaiting trial after being implicated in several murders told the BBC he was part of a DZ Mafia hit squad.
