KAMPALA, UGANDA – The death of prominent Rwandan academic and government critic Aimable Karasira in custody, just days before he was set to be released from prison, has triggered urgent calls for an independent international investigation from leading human rights advocates, who are questioning the official account of his death.
Rwandan authorities confirm Karasira died Wednesday at Kigali’s Nyarugenge District Hospital following what they describe as an overdose of prescription medication for a preexisting chronic condition. In a statement provided to local Rwandan newspaper The New Times, prison system spokesperson Hillary Sengabo claimed Karasira consumed a large excess dose of medication that had been issued to him by prison health services.
But Human Rights Watch has openly challenged this official narrative, calling on the global community to prioritize this case and pushing for a committee of independent international experts to conduct a full, unfiltered probe into the circumstances of Karasira’s death.
“There are countless grounds to question the circumstances surrounding Aimable Karasira’s death in custody, not least the years of targeted harassment and systematic persecution he faced at the hands of Rwandan authorities,” explained Clémentineine de Montjoye, a researcher for Human Rights Watch. “The Rwandan government carries the legal and moral burden of proving Karasira was not unlawfully killed while in their custody.”
Karasira’s path to arrest began in 2020, when he published a YouTube video discussing the loss of his relatives both during the 1994 Rwandan genocide and in its aftermath, following the rise to power of the rebel front that ended the mass killings. Human Rights Watch documentation shows that after the video’s release, Karasira faced sustained pressure from Rwandan intelligence services and anonymous threats from unknown actors.
He was taken into custody in 2021, facing multiple charges including genocide denial and inciting ethnic division. He was convicted on some counts and acquitted on others, but prosecutors launched an appeal of the acquittals, demanding a 30-year prison sentence that was still pending at the time of his death. Because Karasira had already served four years of a five-year total sentence while awaiting trial proceedings, his release was scheduled for May 6, just days after his death was announced.
Michela Wrong, a British historian who has extensively documented alleged human rights abuses under the current Rwandan government, said Karasira’s death reveals deep-rooted issues within the country’s criminal justice and political system. “He told multiple visitors he was being beaten and tortured while in custody,” Wrong wrote on social platform X. “Prison eventually proved a fatal experience, as it has for so many dissidents in Rwanda. Now officials claim he died of an overdose of his own prescription medicine.”
Human Rights Watch has drawn parallels between Karasira’s death and the 2020 in-custody death of Kizito Mihigo, a popular Rwandan singer and fellow government critic. The organization noted both figures held significant moral authority that resonated widely with the Rwandan public, presenting a unique challenge to the ruling government.
President Paul Kagame’s political party has controlled Rwandan governance since the end of the 1994 genocide. The government has enacted sweeping policy measures to heal ethnic divides, including removing ethnic identifiers from national ID cards and integrating genocide education into national school curricula. Every April, the country holds nationwide solemn commemorations to honor genocide victims, and hundreds of community initiatives led by government and civic groups work to promote national unity. Kagame is widely credited by international supporters with establishing decades of relative stability and economic growth after the genocide.
However, critics have long accused Kagame’s administration of systematically eliminating all political dissent. Detractors characterize his rule as an authoritarian regime that has erased nearly all organized opposition, with opponents regularly imprisoned, forced into exile, disappeared, or dying under suspicious circumstances while in state custody.
