(IBT) – More than 200,000 children are currently used in armed conflicts in several countries across the world. IBTimes UK spoke with Erica Hall, senior child rights policy adviser at World Vision UK, on the causes that lead to child soldier recruitment and the solutions to adopt to ensure children can live a life free from violence and traumas. Hall explained that not only are children forcibly recruited to become soldiers, they also voluntarily join militant groups for different reasons such as to avenge a member of their family or to fight in order to have an income.
