A 16-year-old girl in France has died after she attempted a viral TikTok challenge called 'scarf game'. It is a variation of TikTok's 'blackout challenge' and involves fastening cloth around the neck to asphyxiate oneself until they are unconscious. Identified as Christy Sibali Dominique Gloire Gassaille, the teenager died last month and was laid to rest earlier this week.
