Red Hand Day: Addressing the plight of the world's child soldiers

Around the world, tens of thousands of children are fighting in armed conflicts where they're routinely exposed to violence, sexual exploitation and psychological trauma. Some 40 percent of them are girls. This Red Hand Day, also known as the International Day against the Use of Child Soldiers, we speak to Camille Romain des Boscs, CEO of the NGO World Vision France. She tells us about how to protect the world's most vulnerable children from being recruited and how to rehabilitate those who are.
