Child soldiers are individuals, often under the age of 18, who are recruited or used by armed forces or groups in conflict. They may be forced to fight, serve as messengers, or perform other roles in warfare. This practice is a violation of international law and has devastating effects on the physical and mental well-being of these children. The use of child soldiers is prevalent in various regions, particularly in areas affected by civil wars or political instability. Organizations like the United Nations and Human Rights Watch work to combat this issue and support the rehabilitation of former child soldiers, helping them reintegrate into society.
