Brazil's women take on 'rape culture'

In Brazil, the alleged mass rape of a 16-year-old girl by up to 33 men in Rio has been raising widespread debate – and triggered demonstrations in 11 Brazilian cities to call for an end to violence against women.

Almost 50,000 cases of rape were registered in Brazil in 2014 and there is fear that the numbers are radically under-reported.
