Tanzania secured a leadership role at the United Nations Environment Assembly after Minister of State Hamad Yussuf Masauni was elected Vice President. The African Group nominated Masauni, and members endorsed the choice without opposition during the seventh UNEA session in Nairobi. The appointment places Tanzania in the Assembly’s Bureau, which guides global environmental policy and priorities, and reinforces the country’s role in climate action, environmental protection, and sustainable development.

Tanzania’s Legal and Human Rights Centre (LHRC) filed a case at the East African Court of Justice challenging the government’s nationwide internet shutdown imposed from October 29 to November 4. The group argues the blackout violated the East African Community treaty and disrupted banking, health, emergency, and election information services. LHRC seeks a declaration of illegality, a ban on future shutdowns without legal authority, and a public apology.

Tanzania engaged the United Nations after widespread post-election violence and international criticism following the October 29, 2025, vote. President Samia Suluhu Hassan sent a senior envoy to UN Secretary-General António Guterres to discuss national unity and ongoing investigations into the unrest. The opposition party Chadema rejected the election results, called for a UN-supervised transitional government, and demanded new polls. The violence left hundreds dead, over 2,000 arrested, and raised concerns over electoral irregularities and civil rights.

Tanzania is seeking a Washington-based lobbyist to counter international criticism following post-election violence and to strengthen ties with US policymakers. The government of President Samia Suluhu Hassan aims to shape its narrative amid reports of deaths, detentions, and alleged repression after disputed elections. The effort follows a US State Department review citing concerns over civil liberties, religious freedom, and violence against civilians, which Tanzanian authorities dispute.

Dar es Salaam police detained former minister and MP Geofrey Mwambe over alleged criminal offenses that investigators are still examining. Police arrested Mwambe in Tegeta during a security operation and have held him since. Mwambe filed a court application challenging his detention, which the Kisutu Resident Magistrate’s Court will hear on December 15. Police urged the public to remain calm as legal procedures continue.

Tanzania’s main opposition party, Chadema, called for a transitional government following the disputed October 29 election, which it said lacked legitimacy. Vice Chair John Heche urged UN and African bodies to oversee a new, fair vote and to dissolve the electoral commission. The election, which ruling party President Samia Suluhu Hassan won with over 97% of votes, triggered protests that left hundreds dead and more than 2,000 arrested, according to human rights groups.
