Italian family fosters Gambian migrant: 'The son we never had'

Muhammed Sanneh was an orphan when he left The Gambia aged 16 to try and find a way to support his two younger siblings. They had all been living with his grandmother in the northern town of Basse, where life was a struggle. Five-and-a-half years later, the young migrant lives on the Italian island of Sicily, where he is fluent in Italian and has been fostered by a local family.
