The recruitment and use of children violates their rights and causes them physical, developmental, emotional, mental, and spiritual harm. The impact on their mental and physical well-being breaches the most fundamental human rights and represents a grave threat to durable peace and sustainable development, as cycles of violence are perpetuated. The Paris Commitments adopted in Paris in February 2007 are an expression of strengthened international resolve to prevent the recruitment of children and highlight the actions governments can and should take to protect children affected by conflict. The Paris Principles are the operational guidelines related to sustainable reintegration of children formerly associated with armed forces and groups.
