Guerrilla groups, paramilitaries, government armed forces and national police all perpetrate violence and abuses against civilians, including children and adolescents. These are infractions of international humanitarian law and human rights, yet these crimes are often committed with a high level of impunity. Young people have been killed and maimed, victimized by sexual violence, lured and forced into the ranks of combatants, used as informants, marked as targets and driven from their homes. Young people have been devastated by the culture of crime and violence that has evolved in Colombia due to the nexus of armed conflict, illegal drug trafficking and proliferation of small arms.
