42 instruments that contain even more specific rules regarding the protection of children. Those instruments include the Convention on the Rights of the Child and the various United Nations declarations on the subject. This combination of the regional and universal human rights systems for purposes of interpreting the Convention is based on Article 29 of the American Convention 173 and on the consistent practice of the Court and of the Commission in this sphere. 215. For its part, the Court has found that both the American Convention and the Convention on the Rights of the Child form part of a very comprehensive international corpus juris for the protection of the child that should help the Court establish the content and scope of the general provision established in Article 19 of the American Convention, using specific provisions of the Convention on the Rights of the Child in interpreting Article 174 19 of the American Convention. 216. The Inter-American Court has found, “The special vulnerability of boys and girls due to their condition as such becomes even more evident in a situation of domestic armed conflict, (...), since they are least prepared to adapt or respond to said situation and, sadly, it is they who suffer its abuse in a disproportionate 175 manner.” 217. Regarding Peru, the Commission observes that in 1993 the Committee on the Rights of the Child expressed “its deep concern at the continued violence which has already caused thousands of killings, disappearances and displacements of children and parents” and recommended that “investigations be conducted into cases of extrajudicial executions, disappearances and torture which are carried out in the context of the 176 internal violence prevailing in several parts of the country”. 218. The Commission notes that, according to the Report of the CVR, “13.19% of forced disappearances were committed against persons under the age of 18, which suggests that on certain occasions the 177 practice of forced disappearance was used indiscriminately.” In this regard, the above report says that one of the patterns of disappearance of children emerged "as a consequence of a number of incursions in rural areas and 178 the subsequent detention of the entire family in military barracks,” since, from a logic of war, the killing of 179 children was one of the costs of eradicating subversion, and in the fight to destroy the enemy it did not matter if 180 those killed were innocent, much less children. 219. In the instant case, the Commission has taken it as established that the community of Santa Barbara was regarded by the Army as a "red zone" after the presence was reportedly detected of members of subversive groups that made incursions into nearby mines and population centers, and that the detention of 173 IACHR, Report No. 41/99, Case 11.491, Minors in Detention, Honduras, March 10, 1999, par. 72. 174 I/A Court H.R., The “Street Children” Case (Villagrán Morales et al.).
