Keypoints:
- US bars Tanzanian police official from entering country
- Sanctions linked to alleged torture of activists
- Pressure grows over Tanzania’s human rights record
THE United States has imposed sanctions on a senior Tanzanian police official over alleged human rights abuses tied to the detention and mistreatment of two East African activists, escalating international scrutiny of Tanzania’s security forces and political climate.
The sanctions, announced by US Secretary of State Marco Rubio on Thursday, target Tanzanian Police Force Senior Assistant Commissioner Faustine Jackson Mafwele. The move bars Mafwele from entering the United States over what Washington described as ‘credible information’ linking him to serious rights violations.
The sanctions mark one of Washington’s strongest responses yet to allegations of political repression and police abuses in Tanzania following disputed elections and growing concern over democratic backsliding.
Activists’ detention draws global attention
According to the US State Department, the sanctions stem from allegations surrounding the detention of Kenyan activist Boniface Mwangi and Ugandan journalist and activist Agather Atuhaire in May 2025.
The pair had travelled to Dar es Salaam to observe court proceedings involving opposition leader Tundu Lissu, who faces treason charges in a politically sensitive case that has attracted international concern.
US officials alleged that members of the Tanzanian police detained, tortured and sexually assaulted the two activists while they were in custody. Rubio said the designation against Mafwele was intended to reinforce accountability for serious human rights violations.
Mwangi and Atuhaire later publicly described being held incommunicado for several days before being abandoned near the Kenya-Tanzania and Uganda-Tanzania borders respectively. Africa Briefing previously reported claims by Mwangi’s family that the Kenyan activist had been abducted after entering Tanzania, intensifying regional concern over the case.
The allegations gained wider attention after activists accused Tanzanian security officials of torture and sexual violence during detention, claims that authorities strongly denied.
Tanzanian authorities previously rejected the allegations, with police officials reportedly dismissing the accusations as hearsay. However, rights organisations including Amnesty International and Human Rights Watch have repeatedly called for independent investigations into the claims.
Pressure mounts on President Hassan
The US sanctions against the Tanzanian police chief mark one of Washington’s strongest actions so far against officials under President Samia Suluhu Hassan’s administration.
Hassan initially received praise after taking office in 2021 following the death of former president John Magufuli, particularly for easing restrictions on political opposition and media freedoms. But critics say the political environment has deteriorated ahead of and after the October 2025 elections.
The elections saw Hassan secure a new term with an overwhelming victory after opposition figures accused authorities of intimidation and suppression. The US had already signalled concerns over political violence and democratic backsliding in Tanzania.
Africa Briefing earlier reported that Tanzanian authorities confirmed more than 500 deaths linked to violence following the disputed vote, deepening concerns about the country’s democratic trajectory.
Regional observers and governance experts also questioned whether the election process met African Union democratic standards amid allegations of intimidation and restrictions on opposition campaigning.
A government-appointed commission investigating post-election violence reported that hundreds of people were killed and thousands injured during unrest linked to the polls. Opposition groups claim the actual toll may be significantly higher.
Regional and diplomatic implications
The US sanctions could increase diplomatic pressure on Tanzania at a time when East African governments are facing heightened scrutiny over democratic governance and civil liberties.
Analysts say Washington’s action signals a tougher approach towards individual accountability in Africa, particularly where allegations of torture and politically motivated repression emerge.
The sanctions also come amid broader debate about Tanzania’s international image. Human rights campaigners have criticised attempts by the government to improve perceptions abroad despite ongoing allegations of abuses and shrinking civic space.
Neither the Tanzanian government nor Mafwele immediately issued a formal response to the sanctions announcement.
The US State Department said the measures reflect Washington’s commitment to defending civil society actors and promoting accountability for alleged abuses committed by state officials.
Analysts say the sanctions may further complicate Tanzania’s relations with Western partners ahead of renewed international scrutiny of governance and human rights in East Africa.
