Un calls for immediate release of nigerien rights defender

Niger’s human rights defender Moussa Tiangari held arbitrarily, UN experts declare

The United Nations Working Group on Arbitrary Detention has issued a landmark opinion declaring the detention of Nigerien human rights advocate Moussa Tiangari as arbitrary, demanding his immediate and unconditional release. This decisive stance comes as civil society organizations intensify pressure on Niamey authorities to end what they describe as a systematic pattern of judicial persecution against dissenting voices.

July 8, 2026 — The Working Group’s opinion, adopted on March 23 and publicly released on June 23, 2026, categorically states that Tiangari’s prolonged confinement lacks any legal justification. The 49-year-old activist, who heads the Nigerien NGO Alternative Espaces Citoyens (AEC), has been detained since December 3, 2024, when he was forcibly taken from his Niamey home and held incommunicado for 48 hours before being transferred to the Central Service for Combating Terrorism and Organized Transnational Crime (SCLCT/CTO).

Tiangari’s arrest occurred immediately upon his return from Abuja, where he had attended the board meeting of the Centre for Democracy and Development (CDD), AEC’s partner organization. Days earlier, he had participated in the International Committee of the Red Cross’ (ICRC) seventh edition of the “Itinerant Humanitarian” conference in Abidjan, Côte d’Ivoire, commemorating the 75th anniversary of the Geneva Conventions. The conference focused on challenges to humanitarian action and the need to uphold international humanitarian law.

A day after his return, a journalist with close ties to Nigerien authorities published an article accusing Tiangari of making statements detrimental to the country’s interests during the Abidjan conference. This accusation followed AEC’s organization of a critical conference on November 28, 2024, addressing the military regime’s controversial nationality revocation decree, which included participation from Niamey’s chief prosecutor and former high-ranking officials.

Legal flaws and procedural violations exposed

The UN Working Group’s opinion highlights multiple violations of international human rights law, including:

• Arbitrary deprivation of liberty lacking any legal basis
• Severe breaches of fair trial rights
• Discriminatory motives tied to Tiangari’s exercise of fundamental freedoms

The Group concluded that Nigerien authorities violated at least nine articles of the Universal Declaration of Human Rights and seven articles of the International Covenant on Civil and Political Rights, specifically concerning freedom of expression, opinion, peaceful assembly, and participation in public affairs.

Judicial harassment reaches alarming levels

Tiangari faces multiple charges carrying the death penalty, including:

• “Apology for terrorism” under Article 399.1.17 (bis) of the Nigerien Penal Code
• “Endangering state security” (Articles 62 et seq.)
• “Association with terrorist enterprises” (Article 399.1.19)
• “Endangering national defense” (Articles 66 et seq.)
• “Conspiracy against state authority in collusion with enemy powers” (Articles 62 et seq.)

Despite Tiangari’s detention exceeding 18 months, the Niamey Court of Appeal’s specialized terrorism chamber rejected his provisional release request on May 15, 2026. This decision came just weeks after authorities retroactively amended the Criminal Procedure Code to extend maximum pretrial detention from 12 to 48 months in terrorism cases — a move his legal team condemns as an attempt to prolong his detention.

History of persecution

This isn’t Tiangari’s first encounter with judicial harassment. In 2015, he was detained for 10 days on charges of “endangering national defense” for publishing reports critical of military spending. In 2018, four months of arbitrary detention followed his involvement in peaceful protests against the 2018 finance law. In 2020, he spent six weeks in custody after organizing an anti-corruption rally denouncing embezzlement in military procurement.

Deteriorating civic space under military rule

Tiangari’s case exemplifies the shrinking civic space since the July 27, 2023 coup that brought military leaders to power. Since then, authorities have systematically targeted civil society, opposition figures, and independent media through arbitrary arrests, detentions, and nationality revocations of human rights defenders.

Civil society organizations urge immediate compliance with the UN Working Group’s opinion, demanding Tiangari’s unconditional release, dismissal of all charges, reparations, and an independent investigation into his torture allegations during initial detention. They also call for an end to all judicial harassment against him and other human rights defenders in Niger, stressing the need to uphold international standards for freedom of expression as guaranteed by the ICCPR and African Charter on Human and Peoples’ Rights — both ratified by Niger.
