Human rights groups and international monitors are calling on Niger’s military authorities to end the detention of human rights defender Moussa Tchangari. According to the accounts published by Premium Times, Tchangari is arrested at his home in Niamey on 3 December 2024 by plain-clothed officers, and is later charged with offences described as “criminal association in connection with a terrorist enterprise,” “undermining national defence,” and “intelligence with enemy powers.” The publications also state that advocates view the charges as baseless and politically motivated, and that Tchangari and other detainees remain in prison. The reports say supporters are urging Niger to comply with international legal obligations and to respect fundamental human rights. The calls include requests for the immediate release of Tchangari, alongside other detainees held under similar circumstances. The reporting frames the issue as part of broader concerns about due process and the use of national-security-related charges against civil society actors. The sources do not provide details on evidence presented in court or official responses from Niger’s authorities.
