A/HRC/43/75 would be the simplest and strongest basis for promoting accountability for violations of international human rights and humanitarian law in Libya. 70. UNSMIL continued its work under a joint project with UNDP to support transitional justice and reconciliation at the local and national levels. The aim of the project is to support the Misrata-Tawergha joint committee in implementing a road map that includes supporting transitional justice processes and facilitating the return of internally displaced persons in safety and dignity; addressing allegations of past human right violations; addressing some of the fundamental causes of the conflict between the two communities; and promoting dialogue between them. Approximately 100 families of internally displaced persons have thus far returned to the city, among an estimated 43,000 who had been displaced since the 2011 armed conflict. Technical support 71. UNSMIL/OHCHR continued to engage with the Office of the Prosecutor General and other officials on issues relating to fair trial standards, criminal law reform and accountability, and raised several individual cases of concern and patterns of abuse. 72. In July 2019, UNSMIL participated in a workshop organized in Tunis by the Public International Law and Policy Group on transitional justice in Libya. The workshop gathered representatives of the National Transitional Council fact-finding commission, of the judiciary and civil society organizations, with discussions focusing on the planning of awareness-raising activities on transitional justice. 73. On 22 and 23 June, UNSMIL and UNDP jointly organized a consultation workshop on the return of internally displaced Tawergha in Tunis. The event bought together representatives from Tripoli, Benghazi and other areas to champion a unified vision for their return. 74. On 27 and 28 June, UNSMIL and UNDP jointly organized a consultation workshop in Tunis for youth from Misrata and Tawergha to promote co-existence and to create common ground for reconciliation and social cohesion between young people. VII. United Nations human rights due diligence policy 75. The United Nations system in Libya continued its efforts to implement the human rights due diligence policy on United Nations support to non-United Nations security forces (A/67/775-S/2013/110, annex). UNSMIL and the United Nations country team continued to provide advice and support to Libyan security forces with a view to mitigating the identified risks of grave violations of international humanitarian law, human rights law or refugee law by non-United Nations security forces that have been recipients of United Nations support. 76. In March, under the joint UNSMIL/UNDP project on policing and security, UNSMIL provided technical assistance to the Judicial Police to organize training for 14 police trainers on the new curricula developed by an expert, aiming to provide modern and practical training materials for new recruits, based on international standards. 77. In relation to United Nations support to the Libyan Coast Guard and the Department for Combating Illegal Migration, the country task force decided on 13 November to review relevant risk assessments and related mitigation measures in response to reports of continued grave violations and abuses of the human rights of migrants and refugees. 78. In November, the United Nations Office on Drugs and Crime initiated a risk assessment in accordance with the human rights due diligence policy in relation to a planned project on dismantling criminal networks in Libya involved in migrant smuggling and trafficking in persons and on building the capacity of non-United Nations security forces for this purpose. 13
