A/HRC/4/48 page 41 18. Concerning prison maintenance and repairs and the supply and quality of water, some shortcomings were noticed. Some prisons are located in remote and inaccessible places, restricting family visits. The high-security facilities (“new prison culture”) do not provide an adequate infrastructure for rehabilitation and resocialization. 19. During 2006, the National Penitentiary and Prison Institute (INPEC) worked on the establishment of general guidelines and actions in support of members of vulnerable groups. Such efforts must be increased in order to improve the situation in areas such as health care, food, infrastructure for disabled people, care for older people and people with HIV/AIDS, medical care for women and children, and infrastructure for mothers living with their children. Furthermore, policies must be established to ensure that prisoners belonging to indigenous groups can practise their customs and traditions and have access to interpreters and to special training and work programmes. 20. With the support of UNAIDS, the INPEC has made considerable efforts to gather data on the prison population living with the AIDS virus or suffering from AIDS and requiring medical care and anti-retroviral drugs. 21. It is essential to promote a review of the prison regime in accordance with national and international standards relating to the protection of detainees’ rights. Likewise, the implementation of the recommendations regarding prison overcrowding submitted by the Procurator General to the State in August 2004 remains an unmet challenge. It is also important that the Government convene the High Council on Criminal Policy. Children 22. The illegal armed groups continued to commit murders and acts of sexual violence against boys and girls. Furthermore, children continue to be among the main victims of anti-personnel mines. The recruitment of children by illegal armed groups, especially the FARC-EP, continues to be practised and is particularly blatant in the departments of Arauca and Putumayo. Reports were received of extrajudicial executions and sexual violence against boys and girls attributed to the security forces. Information was also received on the occupation of schools by members of the State armed forces, and on the use of children in military and intelligence activities. Approximately 50 per cent of the displaced population is made up of children. 23. In 2006, the new Code on Childhood and Adolescence was enacted. This instrument includes a gender perspective and provisions aimed at protecting children from the internal armed conflict. One of the more serious challenges inherent in the implementation of the Code is the design, implementation and evaluation of public policies on childhood and adolescence at the national, departmental and municipal levels. Women 24. The situation of violence, the conflict and the demobilization process continue to have specific effects on women. In the departments of Arauca, Cauca, Nariño, Norte de Santander, Putumayo and Valle, cases of murder, threats, and sexual violence continued to be reported.
