Violence against children is widespread and tolerated around the world, a report by the UN has claimed.
A four-year study to be presented in New York says many youngsters faced physical abuse that was either hidden or socially approved.
Almost six million children have been forced into work and many more have become prostitutes, the UN said.
In a separate report, Save the Children claimed more than a million children worldwide have been imprisoned.
