CRC/C/KHM/CO/2-3 (f) Children who are detained have no or little access to education or vocational training, limited access to counselling services, including for drug and alcohol addiction, and to recreational activities; (g) Monitoring the situation of children in prisons is subjected to serious restrictions; (h) There is a lack of rehabilitation programmes and a limited number of specialized trained staff and social workers to deal with children in contact with the law. 77. The Committee recommends that the State party bring the system of juvenile justice fully in line with the Convention, in particular articles 37, 39 and 40, and with other relevant standards, including the Standard Minimum Rules for the Administration of Juvenile Justice (the Beijing Rules), the Guidelines for the Prevention of Juvenile Delinquency (the Riyadh Guidelines), the Rules for the Protection of Juveniles Deprived of their Liberty (the Havana Rules), the Vienna Guidelines for Action on Children in the Criminal Justice System; and the Committee’s general comment No. 10 (2007) on the rights of the child in juvenile justice. In particular, the Committee urges the State party to: (a) Establish specialized juvenile courts throughout the country; (b) Ensure that no child is subjected to abuse and torture when in contact or in conflict with the law, especially during the stages of arrest and investigation ; (c) Provide children, both victims and accused, with adequate legal and other assistance at an early stage of the procedure and throughout the legal proceedings; (d) Ensure that children deprived of liberty or in rehabilitation centres or detention facilities are never kept with adults, that they have a safe, child-sensitive environment, that they maintain regular contact with their families and are provided with food, education and vocational training; (e) Provide children deprived of liberty in any form the right to review the placement decision; (f) Promote alternative measures to detention, such as diversion, probation, counselling, community service or suspended sentences, wherever possible; (g) Request further technical assistance in the area of juvenile justice and police training from the Interagency Panel on Juvenile Justice, which includes UNODC, UNICEF, OHCHR, and NGOs.
