S/2017/249 in cases involving four combatants affiliated with the t hen Mouvement du 23 Mars for rape and three Nyatura combatants for sexual slavery. Arrests were also made in cases of sexual violence against children in Kavumu, South Kivu. On 17 March, a witness was assassinated following his testimony in the case. Human rights defenders supporting sexual violence trials have also reported intimidation by the authorities in South Kivu province. The Ministry of Justice and Human Rights and military judicial authorities, with the assistance of the Team of Experts, UNDP, MONUSCO and the International Center for Transitional Justice, prioritized 26 of the gravest cases of conflict-related sexual violence for prosecution. 36. Several mass rape incidents dating back to 2010, such as the Walikale, Bushani, and Kalambahiro cases, remain unresolved, with arrest warrants still unexecuted, with the exception of that for Séraphin Lionso, whom the Government arrested in connection with the Walikale mass rape of 387 victims. Other members of his group, the Mai Mai Cheka, remain active in the conflict and continued to commit rapes in 2016. On 29 July, my Special Representative again urged the Government to act on the arrest warrant against Ntabo Ntaberi Cheka, the leader of the group. Judicial awards of reparations to rape victims, for whi ch the State is liable, remain unpaid. 37. With respect to service delivery, the United Nations Children’s Fund (UNICEF) and partners in North and South Kivu provided medical, psychosocial, legal and socioeconomic reintegration support to 1,410 survivors o f rape by combatants. Despite ongoing efforts by the Government and partners, challenges remain in providing multisectoral assistance to survivors in the east, owing to the limited reach of national institutions. In particular, access to post -exposure prophylaxis, treatment for sexually transmitted infections and mental health support is inadequate. In October, the Personal Representative of the President on Sexual Violence, in partnership with the United Nations, convened a high -level conference in Kinshasa to evaluate progress made on implementing the joint communiqué by my Special Representative and the Government on sexual violence in conflict, resulting in a three-year road map of national priorities (2017-2019). Recommendation 38. I urge the Government of the Democratic Republic of the Congo to sustain its efforts to combat sexual violence, including by bringing perpetrators to justice irrespective of rank or affiliation, ensuring that victims and witnesses are protected and that reparations are paid. I call on the authorities to implement action plans for the army and police, as well as the road map of priorities, and to scale up services, including socioeconomic reintegration support. Iraq 39. Since the rise of Islamic State in Iraq and the Levant (ISIL/Da’esh) in 2014, civilians have been subjected to sexual violence on a horrific scale, notably during the brutal attacks by ISIL on Mosul, Sinjar, Tall’Afar and the Ninewa plains in the north. In the context of ongoing military operations, launched in October 2016, to reclaim Mosul and its environs, the United Nations Assistance Mission for Iraq continues to receive reports of such violations committed by ISIL, primarily against women and girls from ethnic and religious minority groups.
