A/70/162 end attacks on education and health care” in May 2014, which was co -produced by the Special Representative and other organizations of the United Nations system. In her own efforts to promote the guidance note, the Special Representative attended a workshop on the protection of schools and hospitals in January 2015 in Berlin at the invitation of the Federal Foreign Office of Germany and the German Institute for International and Security Affairs. Prevention of the violation of the rights to education and health was also supported by the Security Council through its resolutions 1998 (2011), 2143 (2014) and 2225 (2015), in which the Council urged all parties to conflict to respect the civilian character of schools and to refrain from actions that impeded children’s access to education and health care. 19. The accountability of those who attack schools and hospitals is a key aspect of prevention. The Special Representative appreciates the importance conferred to the protection of education and health of children by Mem ber States and reiterates her call to them to consider, where needed, changes in national policies, military procedures and legislation. Those who deliberately target schools and hospitals must be investigated and prosecuted. 20. In its resolution 2225 (2015), the Security Council also encouraged Member States to take concrete measures to deter the military use of schools by armed forces and armed groups. In that regard, the Special Representative welcomes the adoption by 37 countries of the Safe Schools Declaration on 29 May 2015, which endorsed the Guidelines for Protecting Schools and Universities from Military Use during Armed Conflict. An additional 10 countries have adopted the Declaration since its launch. Although the Guidelines are not legally binding, they highlight good practice for all parties to conflict and aim to provide guidance to reduce the impact of armed conflict on education, particularly in relation to military use. 21. The Special Representative underlines the continuing importance o f efforts to protect education in conflict situations, such as the dedication of the Nobel laureate Malala Yousafzai, the work of the United Nations Special Envoy for Global Education, the No Lost Generation initiative by the United Nations and its partner s for children affected by the conflict in the Syrian Arab Republic, the Oslo Summit on Education for Development, the Incheon Declaration, the planned data hub project by Protect Education in Insecurity and Conflict on global attacks on education, and the Children of Peace initiative of the European Union. With 39 million children and adolescents deprived of education owing to conflict and internal and cross -border displacement, however, those efforts are only a small step towards the goal of safeguarding universal education for those affected by conflict. 22. Ensuring access to education and health care for children in conflict and for displaced children must be a priority. The General Assembly will be endorsing the sustainable development goals at its seventieth session. In the implementation of the goals, the Special Representative urges Member States to prioritize addressing the impact of conflict on the rights of children to education and health. III.
