A/67/256 (c) Ensuring that those using explosive weapons in contravention of international law are held accountable. 70. The Special Representative again urges all armed actors to review, as a matter of priority, the use of aerial attacks, including drones, and night raids so as to prevent incidental loss of civilian life, injury to civilians and damage to civilian objects. 71. With regard to the prevention of the recruitment and use of children, the Special Representative calls upon relevant Member States: (a) To ensure enforcement of legislation prohibiting child recruitment and to strengthen community-based child protection mechanisms as a critical measure to prevent child recruitment; (b) To develop prevention strategies, including through the provision of formal and/or informal education services to children and young people, in addition to the establishment of job-creation and income-generation programmes; (c) To provide official development assistance to Governments in the implementation of prevention strategies. 72. The Special Representative reiterates her call for States to sign, ratify and/or accede to the Optional Protocol to the Convention on the Rights of the Child on the involvement of children in armed conflict, and in so doing, to establish 18 years as the minimum age for voluntary recruitment into their armed forces when depositing their binding declaration (under article 3) upon ratification of the Optional Protocol. 73. The Special Representative encourages Member States to continue to support the mainstreaming of child protection in United Nations activities, both in field missions and at Headquarters, and to facilitate the authorization and timely deployment of child protection advisers in peacekeeping operations and special political missions, as appropriate. 18 12-45308
