A/HRC/24/34 and the scaling-up of humanitarian activities by various organizations. Despite improvements in some basic services, local authorities are struggling to meet the needs of all returnees, particularly in the south.38 48. While significant returns were observed in the south, most IDPs in the north are still reluctant to return home. To date, only about 10 per cent of registered IDPs in the north have done so. According to the International Organization for Migration, approximately 293,000 people remained displaced in Sa’ada, Hajjah, Amran, Dhamar, Al-Jawf and Sana’a as of May 2013. Over 95 per cent of them lived with host communities or in informal settlements. Most IDPs cite security concerns, damaged homes and infrastructure, lack of basic services and disruption to livelihoods as the main obstacles to return. Others, who were involved in political activity, fear possible persecution by groups that control parts of northern Yemen.39 49. On 25 June 2013, the Government approved a national policy to address internal displacement. The policy, which was developed by the Executive Unit for Internally Displaced Persons in cooperation with the Office of the United Nations High Commissioner for Refugees (UNHCR), through extensive consultations with all stakeholders, including IDPs, includes three strategic objectives: prepare for new displacement and protect civilians from involuntary displacement; protect and assist IDPs and displacement-affected communities; and create conditions for durable solutions. The adoption of the policy will be followed by the creation of a special committee led by the Prime Minister. 50. According to data provided by UNHCR, as of 30 April 2013, the number of refugees was 242,000. As compared to 2012, fewer migrants are arriving in Yemen. However, migrants continue to face exploitation, physical and sexual abuse. Of particular concern are reports of increased human trafficking, including of children, reportedly organized by a network composed of Yemenis, including tribal leaders and officials, as well as nationals of neighbouring countries, who subject migrants, including refugees, to gross human rights violations such as torture, sexual violence and slavery.40 H. Cooperation with OHCHR 51. In its resolution 21/22, the Council requested the High Commissioner to provide technical assistance and to work with the Government of Yemen, as needed, to identify additional areas of assistance to enable Yemen to fulfil its human rights obligations. On 26 September 2012, OHCHR and the Government of Yemen signed the Host Country Agreement formally establishing an OHCHR field presence in Yemen. 52. OHCHR-Yemen has, inter alia, provided technical assistance and inputs related to the draft laws on transitional justice. OHCHR-Yemen has also worked with the Ministries of Human Rights and of Legal Affairs to advocate for the establishment of a national commission of inquiry to investigate the human rights violations that took place during the events of 2011 and provided detailed comments on the draft decree establishing this commission. Most of the comments were accommodated in the decree issued. 38 39 40 14 OCHA, Humanitarian Bulletin. Ibid. Ibid. Since early April 2013, Yemeni military forces raided the borders between Saudi Arabia and Yemen targeting smugglers’ camps in Yemen and resulting in the mass release of Ethiopian migrants. UNICEF and partner organizations, who were able to rescue and register 347 children (334 boys, 13 girls), have expressed their concerns that the actual figure of migrant children and victims of child trafficking could be higher.
