The killings that followed Tanzania’s 29 October 2025 election demand an explanation that reaches beyond the events themselves. Nyerere to Samia: The Road to Tanzania’s Post–October 2025 Election Massacres traces the institutions, political networks and security practices built across six presidencies—and asks how they made such violence possible.
🔎 Pambalu, Lissu and Mwaipaya Cases Converge in Five Days Before Tanzania’s Anniversary
Within five days, two treason cases against CHADEMA leaders converged with a cross-border abduction and the Catholic Church’s nationwide commemoration plans. The sequence below covers confirmed events and scheduled dates within the assessment window.
⚖️ Tundu Lissu Announces Hunger Strike Over Alleged Defiance of High Court Order at Ukonga Prison
CHADEMA announced that Lissu will begin a hunger strike from Monday to force prison authorities to allow private meetings with his lawyers. The High Court had ruled in his lawyers’ favour on consultation restrictions at Ukonga Prison, in a judgment reported on 17 October. The party accuses the authorities of failing to respect the ruling.
CHADEMA secretary-general John Mnyika said Lissu fears for his life and questions whether food supplied by officials defying a court order can be trusted. His lawyer, Rugemeleza Nshala, said consultations had been denied despite the order, and that on some occasions access had been barred altogether. Nshala also said Lissu relies on medication and is prepared to stop taking it. The Citizen separately reported his threat to refuse medication.
Lissu survived being shot 16 times in 2017. He has been detained for more than 18 months and conducted a previous hunger strike in May 2025 over remote court hearings. In July 2026, a statement on his X account warned that his life was at serious risk. As of 24 October, prison authorities, police and the government had issued no public statement on the planned strike.
🧑⚖️ John Pambalu Becomes Second CHADEMA Leader Charged With Treason
Pambalu is a member of CHADEMA’s national council and former leader of its youth wing. He was charged with treason on Wednesday, an offence carrying a potential death sentence. The charge sheet accuses him of seeking to obstruct the 2025 General Election and of conducting continuous protests to intimidate the executive.
He is the second CHADEMA leader to face treason charges after Lissu. Speaking at a public meeting in Arusha, deputy chairman John Heche said he expected a similar case against himself but would not leave the country.
🚨 Twaha Mwaipaya Abducted by Three-Vehicle Team in Kamulu Near Nairobi
Amnesty International Kenya reported that Mwaipaya was abducted at around 2pm on 25 October in Kamulu, Machakos County, while travelling by taxi to visit friends. The abductors used three vehicles, including a Toyota Land Cruiser Hardtop. Mwaipaya became BAVICHA’s national mobilisation coordinator in 2019 and is a prominent critic of President Samia Suluhu Hassan’s administration.
He fled to Kenya in 2025 after imprisonment in 2022, and has nearly 600,000 Instagram followers. CHADEMA and Amnesty both confirmed the kidnapping. CHADEMA foreign affairs chief John Kitoka, himself in exile in Nairobi, said he feared for Mwaipaya’s life and his own safety. Tanzanian activist Maria Sarungi Tsehai appealed for Toyota Hardtops to be inspected at the border crossings, particularly Namanga. At the time of writing, Mwaipaya’s whereabouts and the identity of his abductors remain unknown.
⛪ Catholic Bishops and Rights Defenders Prepare to Mark the 29 October Massacres
The Tanzania Episcopal Conference has ordered memorial Masses nationwide on Thursday 29 October in parishes, prayer centres and Church institutions. The letter, signed by TEC President Bishop Wolfgang Pisa, dedicates the Masses to those killed, injured or missing, and to their families. The Tanzania Human Rights Defenders Coalition has advised President Samia to declare a memorial day on 29 October.
The anniversary commemorates approximately 10,000 people killed, the figure documented in the Intelwatch dossier submitted to the International Criminal Court. The state’s Chande Commission recorded 518. Its own chairman conceded the true toll was likely higher because some families buried relatives without taking bodies to morgues.
The UK Foreign Office updated its travel advice on 20 October. It notes social media calls for demonstrations on the anniversary, previous internet restrictions during protests, and that security services may check phones for election-related content. President Samia is scheduled to inaugurate the Government City on 30 October.
