CRC/C/COD/CO/3-5 B. General principles (arts. 2, 3, 6 and 12) Non-discrimination 15. While noting the persistent discrimination against children in vulnerable and marginalized situations, including children with disabilities, children with HIV/AIDS, children accused of witchcraft, children with albinism, indigenous children, lesbian, gay, bisexual and transgender children, demobilized child soldiers and internally displaced children, and the lack of an overall strategy to combat such discrimination, the Committee recommends that the State party adopt comprehensive legislation prohibiting discriminatory behaviour on any grounds. The Committee, reiterating its previous recommendation (see CRC/C/COD/CO/2, para. 29), also urges the State party to: (a) Take all measures, including administrative measures, to ensure the implementation of legislation protecting children against discrimination; (b) Adopt a comprehensive strategy to eliminate discrimination on any grounds and against all vulnerable groups; (c) Conduct studies to identify and act on causes of discrimination, carry out awareness-raising activities in order to combat such discrimination, and train professionals working with and for children. Best interests of the child 16. Given that there are gaps in the implementation of article 6 of the Child Protection Code, which provides for the best interests of the child to be considered in all decisions concerning him or her, the Committee, in the light of general comment No. 14 (2013) on the right of the child to have his or her best interests taken as a primary consideration, recommends that the State party: (a) Ensure that this right is integrated appropriately and applied consistently in all legislative, administrative and judicial proceedings, as well as in all policies, programmes and projects that are relevant to and have an impact on children; (b) Develop procedures and criteria to provide guidance to all relevant persons in authority for determining the best interests of the child in every area and for giving it due weight as a primary consideration. Right to life, survival and development 17. The Committee remains seriously concerned about: (a) Grave violations committed against children by State and non-State armed forces in the context of the armed conflict, including the killing, maiming and abduction of children — both civilians and those recruited by the non-State armed groups; (b) The child mortality rate, in particular the fact that despite some decrease, especially among those under the age of five years, the rate remains extremely high in the State party, especially in rural areas, and is reportedly caused by preventable diseases, such as malaria and HIV/AIDs, among others; (c) The lack of appropriate medical assistance provided to mothers, including adolescent mothers, during and after the delivery of their baby; (d) The reports of prevalent violence against, ritual killings of and abductions of children with albinism, as well as the mutilation of such children for the purpose of selling 5
