A/HRC/40/28 that the children affected have access to special educational programmes and skills training. Caregivers of child victims and witnesses should also have access to appropriate support. 71. In their prevention efforts, States should recognize that the factors that place children at risk of exploitation by a terrorist group overlap with risk factors for other forms of exploitation. Child protection measures should take a holistic approach to those risks, in partnership with children, their families and their communities. In particular, States should take measures to address child poverty, to ensure that all children have access to quality education without discrimination and to resolve community grievances. 72. In line with their international obligations, States should explicitly prohibit and criminalize the recruitment and use of children in hostilities by non-State armed groups, including terrorist groups. Cases of exploitation of children by such groups should be investigated and the perpetrators brought to justice. Exploited children should have access to comprehensive rehabilitation and reintegration, which should be gender-sensitive. 16
