18. The following chapters summarize international human rights law, especially child rights law, humanitarian law and other international standards applicable to these eight issues. Summarizing these standards is intended to clarify for States how to ensure that measures to address these issues are based on child rights and that “the best interests of the child as well as the specific needs and vulnerabilities of girls and boys are duly considered.”32 United Nations Office on Drugs and Crime, Handbook on Children Recruited and Exploited by Terrorist and Violent Extremist Groups: The Role of the Justice System (2017) The UNODC handbook aims at providing guidance to legal professionals and policymakers, as well as practitioners on the treatment of children targeted by terrorist and violent extremist groups. The publication focuses on the prevention of child recruitment, justice for children, and rehabilitation and reintegration. To complement and build upon the Handbook, in 2019, UNODC has developed three training manuals to support practitioners and policymakers in designing and implementing effective interventions: (i) Prevention of Child Recruitment by Terrorist and Violent Extremist Groups; (ii) Justice for Children in the Context of Counter-Terrorism; and (iii) Rehabilitation and Reintegration of Child Victims of Recruitment and Exploitation by Terrorist and Violent Extremist Groups.
