A/HRC/34/44 Operations and the Deputy Secretary-General to discuss ways to further strengthen the protection of children in NATO-led operations. She also briefed the Operations Policy Committee and underscored the responsibility and role of NATO in protecting children in armed conflict. During her visit to Afghanistan in February 2016, the Special Representative met with the Commander of the NATO Resolute Support Mission and the NATO Senior Civilian Representative to voice concerns about rising child casualties and to advocate for the appointment of an adviser on children and armed conflict, within the Resolute Support Mission in Afghanistan. The position was filled in May 2016. 50. The Office of the Special Representative contributed to the development of NATO policies and guidelines on children and armed conflict, including the “standard operating procedure on reporting and information-sharing in support of children and armed conflict”, which was adopted in September 2016 and identifies the role of NATO in support of the United Nations in protecting children affected by armed conflict. In addition, staff of the Office of the Special Representative attended the NATO-United Nations staff talks held in March. V. Working with United Nations human rights mechanisms and initiatives 51. Given the ratification of the Convention on the Rights of the Child in October 2015 by Somalia, there is almost universal ratification of that treaty and the global normative framework to protect the rights of children is robust. However, the Special Representative continues to engage with Member States that have not already ratified the Optional Protocol to the Convention on the Rights of the Child on the involvement of children in armed conflict, with the aim of achieving universal ratification thereof and enhancing the legal protection of children’s rights in conflict.

Four additional countries — Brunei Darussalam, Guinea, Pakistan and Samoa — became States parties to the Optional Protocol during the reporting period. 52. While this international legal framework has sometimes been supported and enhanced by legislation and policies adopted at the regional, national and local levels, the present report has outlined how there is a disconnect between the internationally agreed standards for children’s rights and their practical implementation in situations of armed conflict. In this regard, the Special Representative has continued to prioritize closer cooperation between her Office and international human rights mechanisms, in particular the Committee on the Rights of the Child and the Human Rights Committee. Through State reporting mechanisms, treaty bodies have played an important role in identifying gaps between the legal and policy framework and the practice, and have made recommendations to address any shortcomings. The Special Representative is encouraged by the continued attention given to both progress and challenges in addressing the impact of armed conflict on children in State parties’ reports reviewed by the respective committees. For example, in the reports of the Democratic Republic of the Congo to the Committee on the Rights of the Child (CRC/C/COD/3-5) and the Human Rights Committee (CCPR/C/COD/4), the State party referred to the progress achieved in implementing the action plan to end the recruitment and use of children and other serious violations of the rights of the child by the armed forces and the security services. In this regard, increased collaborative efforts between the State party, the Special Representative and relevant special procedures of the Human Rights Council have been highlighted as a way forward to put an end to the suffering of children caused by the armed conflict.
