Moussa tiangari’s unjust detention sparks rights group outcry in Niger

Niger’s government faces urgent calls to end arbitrary detention of human rights defender

Human rights organizations are demanding the immediate release of Moussa Tiangari, a prominent civil society activist and human rights defender in Niger. The call comes after six months of arbitrary detention, with activists warning that terror-related charges are being weaponized to silence dissenting voices.

Escalating repression through counter-terrorism laws

On December 3, 2024, plainclothes officers forcibly entered Moussa Tiangari’s home in Niamey, Niger’s capital, and confiscated his personal devices. After two days of enforced disappearance, he was located at the Central Service for Combating Terrorism and Transnational Organized Crime. On January 3, 2025, the Niamey court charged him with serious offenses including:

• “Association of criminals in relation to a terrorist enterprise”
• “Undermining national defense”
• “Conspiracy against state authority in collaboration with hostile powers”

The latter charge carries the death penalty if proven. Despite these grave accusations, Tiangari has not been brought before a judge to review the lawfulness of his detention during his six months in Filingué prison, 170 kilometers from the capital.

Silencing legitimate dissent

Human rights groups argue that Tiangari’s prosecution stems directly from his public criticism of government policies. In November 2024, he publicly condemned:

• The Interior Minister’s decision to revoke licenses of two humanitarian NGOs
• The creation of a terrorism-linked database that threatens civil liberties

These actions follow a 2024 decree establishing a registry of individuals and groups associated with terrorism and national defense crimes. Tiangari now risks losing his Nigerien citizenship due to these baseless terrorism allegations.

International condemnation of Niger’s judicial overreach

Amnesty International, Human Rights Watch, the International Federation for Human Rights (FIDH), and the World Organisation Against Torture (OMCT) have jointly condemned Tiangari’s detention as arbitrary. They note that Nigerian counter-terrorism laws allow up to four years of pre-trial detention—unrenewable periods that appear to be weaponized against critics.

«Moussa Tiangari is being punished simply for exercising his fundamental rights,» stated the interim West and Central Africa Regional Director of Amnesty International. «The authorities must drop all charges immediately and end this judicial harassment that stifles peaceful dissent.»

The organizations have documented a pattern of repression since the 2023 military coup, where authorities have systematically targeted opposition figures, media outlets, and peaceful dissidents. A March 2025 Amnesty report highlighted the systematic suppression of former government officials and critical voices.

Legal battles and international appeals

Tiangari’s legal team has filed multiple motions to dismiss the case and disqualify the specialized terrorism court, but both were rejected in March and May 2025. Appeals are currently pending. Meanwhile, the international community continues to demand his immediate and unconditional release, with Amnesty members worldwide mobilizing in his support.

Who is Moussa Tiangari?

At 55, Tiangari serves as Secretary-General of Alternatives Espaces Citoyens (AEC), a leading Nigerien civil society organization. His arrest and prolonged detention have drawn global attention to the deteriorating human rights situation in Niger, where the military junta has increasingly used counter-terrorism legislation to suppress legitimate political activity.

Human rights defenders stress that Tiangari’s case exemplifies the junta’s broader strategy to eliminate dissent through judicial persecution, raising serious concerns about Niger’s democratic trajectory.
