A/HRC/31/3 Timor-Leste and the United States. A campaign video that was launched in May and showcases the diversity of lesbian, gay, bisexual, transgender and intersex people and their contributions to the community, was watched by almost 10 million people online. In Mexico City, the subway system broadcast the campaign for five months on a line used daily by about 400, 000 passengers. 46. In September, OHCHR hosted an expert meeting in Geneva to discuss the specific human rights challenges faced by intersex people — including unnecessary and involuntary surgery and other medical treatments, as well as lack of access to justice and discriminatory practices in education, employment and sport. OHCHR also released a Free and Equal campaign factsheet on human rights and intersex persons, available online. 7. Discrimination against persons with albinism 47. OHCHR held an exhibition entitled “Blanc ebène — White ebony” in March and launched a special website in May (www.albinism.ohchr.org). 48. Further to OHCHR advocacy, national strategies to combat violence and discrimination against persons with albinism were developed in Malawi and the United Republic of Tanzania. In Malawi, OHCHR supported the Ministry of Justice with a view to bringing perpetrators of attacks against persons with albinism to justice. In the United Republic of Tanzania, the United Nations Voluntary Fund for Victims of Torture supported organizations providing direct assistance to survivors of attacks and their relatives. C. Combating impunity and strengthening accountability and the rule of law 1. Transitional justice 49. In February, OHCHR published Rule of Law Tools for Post-Conflict States,5 in which good practices relating to the management of records and archives in the context of the right to truth were identified. OHCHR sought to strengthen national capacity for the investigation and prosecution of serious human rights violations, for example in Cambodia, Colombia and Guatemala. Together with the United Nations Organization Stabilization Mission in the Democratic Republic of the Congo, the United Nations Entity for Gender Equality and the Empowerment of Women and the Special Representative of the SecretaryGeneral on Sexual Violence in Conflict, OHCHR prepared a submission (amicus brief) on reparations in relation to the case The Prosecutor v. Germain Katanga before the International Criminal Court.6 50. OHCHR continued to provide technical advice in relation to transitional justice mechanisms and related national dialogues. For instance, in the Central African Republic, it provided legal advice on the creation of a hybrid special criminal court to deal with serious human rights violations committed since 2003 and, in September 2015, co-organized with the United Nations Multidimensional Integrated Stabilization Mission in the Central African Republic and local authorities an international seminar on the fight against impunity.7 In Mali, South Sudan and the Sudan (Darfur), OHCHR provided advice on possible accountability and transitional justice arrangements foreseen by peace agreements. OHCHR continued to support the Extraordinary African Chambers in the Senegalese Courts and monitored the trial of Hissène Habré. 5 6 7 8 See www.ohchr.org/Documents/Publications/HR_PUB_14_4_Archives_en.pdf.
