A total of 518 people died in Tanzania from unnatural causes, including 197 who were shot dead, in the widespread protests that followed last year's general election, a commission of inquiry announced.
Commission chairman Mohamed Chande Othman did not say who was responsible for the deaths, recommending further investigations.
This is the first time the authorities have declared how many people died.
Opposition parties and human rights groups accused security forces of a brutal crackdown, claiming that thousands were killed.
President Samia Suluhu Hassan was declared the winner of the election with 98% of the vote, a result described by opposition as a mockery of democracy.
While the president stated the elections were fair and blamed foreigners for inciting violence, international observers raised concerns regarding transparency in the electoral process.
The violence has shocked a nation known for its stability, with the inquiry exposing underlying social, economic, and political grievances used by protest leaders.
The commission's report suggests a need for free medical treatment for victims, and even recommendations for a new constitution by 2028.
The report indicates that the scale of violence could be higher, as some victims were buried without official record.
The president has defended security agency actions, claiming they prevented anarchy, and plans to establish a criminal investigation body to examine the unrest related to the elections.
This inquiry comes amidst ongoing debates about political reforms in Tanzania, where the two main opposition leaders face political hurdles ahead of the upcoming elections.
