CRC/C/COL/CO/3 page 17 targeted attention and assistance available for displaced children, especially since it is estimated that children constitute more than half of the displaced population. In addition, the Committee is concerned that inadequate attention is paid to the physical protection of internally displaced children and their need for psychosocial assistance in order to overcome the trauma of displacement. 79. The Committee recommends that the State party: (a) Substantially increase the resources allocated for internally displaced persons and implement targeted programmes for children in order to provide them with adequate access to food, shelter, education and health services. In this respect the Committee recommends that the State party further strengthen its cooperation with UNHCR and fully adhere to the Guiding Principles on Internal Displacement (E/CN.4/1998/53/Add.2) and Constitutional Court decision T-025 of 2004; (b) Pay additional attention to the psychosocial assistance required by children who have been displaced and provide further protection for girls against gender-based violence; (c) Distribute humanitarian assistance by civilian authorities in order to maintain the principle of distinction and not to increase the vulnerability of the displaced population and those at risk of displacement by exposing them to subsequent retaliation by members of illegal armed groups. Children in armed conflict 80. The Committee, while welcoming the ratification of the Optional Protocol to the Convention on the involvement of children in armed conflict, is seriously concerned over the grave consequences the internal armed conflict has on children in Colombia, causing them serious physical and mental injury and denying them the enjoyment of their most basic rights. The Committee notes as positive the development of educational kits distributed to schools in high-risk conflict areas by the army, as well as certain efforts to improve the reintegration and recovery of demobilized child soldiers. However, the Committee considers that considerable measures for demobilized and captured child soldiers are still lacking. In particular, the Committee is concerned over: (a) Large-scale recruitment of children by illegal armed groups for combat purposes and also as sex slaves; (b) Interrogation of captured and demobilized child soldiers and delays by the military in handing them over to civilian authorities in compliance with the time frame of maximum 36 hours stipulated in the national legislation; (c) The use of children by the army for intelligence purposes; (d) Inadequate social reintegration, rehabilitation and reparations available for demobilized child soldiers;
