Four people have died in the latest fire tragedy in a Mumbai high-rise. But those numbers could have been much higher had it not been for the presence of mind of 10-year-old Zen Sadavarte. She is being credited with saving the lives of 13 people by making wet masks for them and escorting them to a neighbour's flat for safety. Zen told NDTV she remembered tips from a school project she had done in Grade 3. 10-year old Zen is now in Grade 6.
