Millions of children are impacted by armed conflict worldwide. While international responses to armed conflict recognize the need for decisive action to end crimes against and affecting children, a justice gap persists when it comes to child victims. This reflects a gap in capacity when it comes to child-sensitive investigations. Lack of specialized knowledge and training in child interviewing is commonly cited as a problem hindering the effectiveness of investigations. Children continue to be underappreciated as sources of evidence in favour of other primary and secondary sources, such as parents and older siblings, and while there are often valid trauma-informed reasons for this practice, it may also reflect a lack of understanding or confidence in how to obtain best evidence from children. These problems are compounded when it comes to child victims of conflict-related sexual violence.
