The October 29, 2025 general elections in Tanzania have triggered serious political upheaval marked by widespread violence, repression, and accusations of human rights abuses that have plunged the nation into crisis. While President Samia Suluhu Hassan was officially declared re-elected with 97.66% of the vote, the electoral process has been heavily criticized for lacking credibility, fairness, and transparency. The aftermath has seen reports of mass killings, arbitrary arrests, internet shutdowns, and suppression of the opposition and media, undermining fundamental democratic principles.

Background: An Election Marked by Repression and Violence

The electoral environment in Tanzania was far from conducive to free and fair elections. Prior to voting day, opposition parties faced intense government crackdowns that included arrests and prosecutions. The opposition party Chadema boycotted the election after its leader Tundu Lissu was detained on treason charges amid ongoing attempts to silence dissenting voices. As the election took place, observers witnessed low voter turnout indicating widespread voter apathy and disengagement driven by fear and mistrust.

Violent protests erupted in multiple regions including Dar es Salaam, Mbeya, and Mwanza following the announcement of election results. These protests were met with lethal force from security forces. According to claims from opposition sources and rights groups, hundreds and potentially thousands of people were killed. Human Rights Watch reported that security forces used live ammunition on protesters, some of whom were violent but many were peaceful civilians. The African Union’s observation mission underlined that the electoral process “did not comply with AU principles and international democratic standards,” noting that the environment before, during, and after elections was marred by violence and an internet shutdown.​

Mass Killings and Human Rights Abuses: A Dark Chapter

Reports emerged alleging that Tanzanian authorities attempted to conceal the full extent of the killings. Human rights organizations, alongside journalists, have reported mass graves being dug, particularly in Mabwepande, to hide bodies of those killed in the crackdown. Hospitals were reportedly militarized with police and intelligence agents guarding them, confiscating phones, deleting footage, and preventing families from claiming or identifying bodies. Disturbingly, there were accusations that medical personnel were instructed to harm or even kill patients critically injured during the violence.​

The use of military-grade weapons, reportedly imported via relatives of the president, highlights the severity and premeditation of the crackdown. The violence did not discriminate; victims included protesters, street children, medical workers, and uninvolved civilians. Such actions indicate a systematic attempt to suppress opposition and silence dissent through terror.

Political Repression and Election Integrity

The election process was widely critiqued as uncompetitive, with the opposition largely shut out through arrests, bans, and court cases. The incumbent government imposed draconian measures, including banning opposition rallies, deregistering media outlets, and restricting press freedoms. The internet blackout coinciding with and following election day added to the opacity of the electoral process, preventing citizens and observers from accessing timely information.

The opposition reported fearing a "sham" election manipulated to favor the ruling party. The African Union noted exclusion of opposition candidates and pointed to systemic failures within electoral institutions to uphold democratic norms. This disenfranchisement fostered widespread cynicism, leading to low electoral participation—a sign that regular elections without genuine competition can erode civic engagement and trust in governance over time.​

International Condemnation and Calls for Justice

The international response has been swift and unequivocal in condemning the violence and demanding accountability. The United Nations Human Rights Office emphasized the necessity for prompt, impartial investigations, and the release of political prisoners detained arbitrarily. Volker Türk, the UN Human Rights Chief, stressed that the government must ensure respect for rights and justice for victims: "The authorities in Tanzania responded to widespread protests following the October 29 elections with lethal force and other abuses," reflecting the gravity of the crackdown.

Human Rights Watch strongly criticized the government’s approach, describing it as a tool to undermine electoral credibility through brutal repression. Meanwhile, dozens of African civil society organizations have united in calling for President Suluhu’s resignation and prosecution of officials responsible for the killings and abuses. These groups warn that without accountability, violence and impunity will continue to scar Tanzania’s political future.​

Societal Impact and Future Prospects

The extensive use of force against civilians and political opponents risks destabilizing the social fabric of Tanzania. The suppression of dissent and the climate of fear have deepened divisions within society and eroded faith in democratic institutions. The arrest and trial of opposition figures, crackdown on media, and erosion of civil liberties pose significant threats to political pluralism and social cohesion.

Experts who have analyzed Tanzania’s trajectory warn that the ruling party’s increasingly authoritarian tendencies may further alienate citizens and exacerbate unrest. Following similar patterns seen in neighboring countries, the grinding down of opposition and civil society can lead to longer-term instability if not addressed through inclusive dialogue and reforms.

The Imperative for Accountability and Democratic Resilience

Tanzania’s post-election crisis is an urgent call for national and international action to safeguard human rights and democratic governance. The evidence of mass killings, enforced disappearances, and repression laid bare in the aftermath of the 2025 elections demands full independent investigations and justice processes. Transparency, respect for political freedom, and restoration of media and civil liberties must underpin efforts to restore trust and political stability.

As the government faces global scrutiny, its willingness to address these issues will define Tanzania’s path forward. Without meaningful accountability and political reforms, the country risks further authoritarian entrenchment, civil unrest, and deterioration of its democratic institutions.
