Rio de Janeiro favela life described by children

BBC News went to Maré favela to meet 11 year-old twins, Samira and Samir da Silva, to learn how violence affects their daily lives as they grow up in a Rio de Janeiro's shanty town.

Brazil's shanty towns are often associated with criminality and high death tolls and in 2015, more than 100,000 students had their classes cancelled because of shootings near their schools.
