UNPO Expresses Concern About the Arbitrary Arrest of Haratin Human Rights Defender Ms. Warda Ahmed Souleymane

November 13, 2025

The Unrepresented Nations and Peoples Organisation (UNPO) has learned with deep concern of the arbitrary arrest and detention of Ms. Warda Ahmed Souleymane by the Mauritanian authorities on 31 October 2025 in Nuakchott. Ms. Warda Ahmed Souleymane is a Haratin human rights defender and anti-slavery activist in the Islamic Republic of Mauritania. 

According to information received, Ms. Souleymane was arrested by police in the early evening and immediately taken to an unknown place of detention. She had already participated in the 85th Ordinary Session of the African Commission on Human and People’s Rights, and in the NGO Forum in Banjul, Gambia, from 17 to 19 October 2025. There, she made notable interventions on racial discrimination and apartheid, and peacefully called on Mauritanian citizens to engage in civic awareness and take charge of their destiny. 

Following her return to Mauritania, Ms. Souleymane became the target of a sustained defamation campaign on social media. She is reportedly accused of publishing a peaceful call to mobilisation, while other activists from socially dominant groups, who made more provocative statements, have not faced similar reprisals. This is not the first time Ms. Souleymane has been deprived of her liberty for exercising her freedom of expression. She was previously detained on 1 April 2025 for expressing her opinions, and released on 17 April 2025. Her most recent arrest illustrates a pattern of targeted persecution by security services against non-violent dissenting voices in Mauritania. 

Echoing the condemnation by the African Commission on Human and Peoples’ Rights, the UNPO reaffirms its position in protecting human rights defenders from enforced disappearances and arbitrary detentions. As the Commission stated, we remind the Mauritanian authorities of its resolutions ACHPR/Res.196 (L) 11 and ACHPR/Res. 345 (LVIII) 2016 on the situation of human rights defenders in Africa, which condemn any form of intimidation, harassment, or reprisal against individuals or organisations cooperating with the African human rights system. 

The UNPO, together with the Initiative for the Resurgence of the Abolitionist Movement (IRA–Mauritania), strongly condemns the arrest of Ms. Warda Ahmed Souleymane. UNPO calls on the Government of Mauritania to ensure a transparent, independent, and impartial investigation into her arrest, and to put an end to state-sponsored intimidation targeting political and civil society activists. Mauritania must also uphold its international human rights obligations and guarantee the safety and protection of all individuals who peacefully defend fundamental freedoms. In line with the African Commission’s recommendations, UNPO urges the Mauritanian authorities to adopt specific legislation safeguarding human rights defenders.

UNPO emphasizes that the abduction of any activist, and particularly that of a woman leader advocating for justice and equality, constitutes an attack not only on the individual but on civil society as a whole. The continued suppression of abolitionist voices in Mauritania weakens democratic governance and undermines trust between citizens and state institutions.

UNPO stands in full solidarity with Ms. Warda Ahmed Souleymane’s family, the Haratin community, and with all activists and human rights defenders in Mauritania who continue to peacefully advocate for justice, equality, and human dignity despite the mounting repression.

L’UNPO Exprime Son Inquiétude Face à l’Arrestation Arbitraire de Mme Warda Ahmed Souleymane

L’Organisation des Nations et des Peuples non représentés (UNPO) a appris avec une profonde inquiétude l’arrestation et la détention arbitraires de Mme Warda Ahmed Souleymane par les autorités mauritaniennes le 31 octobre 2025 à Nouakchott. Mme Warda Ahmed Souleymane est une défenseuse des droits humains et militante antiesclavagiste haratine en république islamique de Mauritanie.

Selon les informations reçues, Mme Souleymane a été arrêtée par la police en début de soirée et immédiatement conduite vers un lieu de détention inconnu. Elle avait déjà participé à la 85e session ordinaire de la Commission africaine des droits de l’homme et des peuples, ainsi qu’au Forum des ONG à Banjul, en Gambie, du 17 au 19 octobre 2025. À cette occasion, elle a formulé des interventions remarquables sur la discrimination raciale et l’apartheid, et a appelé pacifiquement les citoyens mauritaniens à développer une conscience civique et à prendre en main leur propre destin.

À la suite de son retour en Mauritanie, Mme Souleymane est devenue la cible d’une campagne de diffamation soutenue sur les réseaux sociaux. Elle est, selon les informations rapportées, accusée d’avoir publié un appel pacifique à la mobilisation, tandis que d’autres militants issus de groupes socialement dominants, ayant tenu des propos plus provocateurs, n’ont pas fait l’objet de représailles similaires. Ce n’est pas la première fois que Mme Souleymane est privée de liberté pour avoir exercé sa liberté d’expression. Elle avait déjà été détenue le 1er avril 2025 pour avoir exprimé ses opinions, puis libérée le 17 avril 2025. Sa récente arrestation illustre un schéma de persécution ciblée par les services de sécurité à l’encontre des voix dissidentes non violentes en Mauritanie.

Faisant écho à la condamnation exprimée par la Commission africaine des droits de l’homme et des peuples, l’UNPO réaffirme sa position en faveur de la protection des défenseurs des droits humains contre les disparitions forcées et les détentions arbitraires. Comme l’a souligné la Commission, nous rappelons aux autorités mauritaniennes ses résolutions ACHPR/Res.196 (L) 11 et ACHPR/Res.345 (LVIII) 2016 relatives à la situation des défenseurs des droits humains en Afrique, lesquelles condamnent toute forme d’intimidation, de harcèlement ou de représailles à l’encontre des personnes ou organisations coopérant avec le système africain des droits de l’homme. 

L’UNPO, conjointement avec l’Initiative pour la résurgence du mouvement abolitionniste (IRA–Mauritanie), condamne fermement l’arrestation de Mme Warda Ahmed Souleymane. L’UNPO appelle le gouvernement mauritanien à garantir une enquête transparente, indépendante et impartiale sur les circonstances de son arrestation, et à mettre un terme aux actes d’intimidation étatiques visant les militants politiques et de la société civile. La Mauritanie doit également respecter ses obligations internationales en matière de droits humains et assurer la sécurité ainsi que la protection de toutes les personnes défendant pacifiquement les libertés fondamentales. Conformément aux recommandations de la Commission africaine, l’UNPO exhorte les autorités mauritaniennes à adopter une législation spécifique assurant la protection des défenseurs des droits humains. 

L’UNPO souligne que l’enlèvement de tout militant, et plus particulièrement celui d’une femme dirigeante œuvrant pour la justice et l’égalité, constitue une atteinte non seulement à la personne concernée, mais également à l’ensemble de la société civile. La répression continue des voix abolitionnistes en Mauritanie fragilise la gouvernance démocratique et mine la confiance entre les citoyens et les institutions de l’État.

L’UNPO exprime sa pleine solidarité avec la famille de Mme Warda Ahmed Souleymane, avec la communauté haratine, ainsi qu’avec l’ensemble des militants et défenseurs des droits humains en Mauritanie qui continuent de plaider pacifiquement pour la justice, l’égalité et la dignité humaine malgré la répression croissante.
