Tanzanian President Samia Suluhu Hassan was Monday sworn in for a second term amid tight security, following an election marred by violent protests and rejected by the opposition as a sham.
The inauguration ceremony was held at a military parade grounds in the capital, Dodoma, instead of a stadium as in previous years.
It was closed to the public but is being shown on state TV.
Samia was declared the winner on Saturday with 98% of the vote.
She faced little opposition with key rival candidates either imprisoned or barred from running.
International observers have raised concerns about the transparency of the election and its violent aftermath, with hundreds of people reportedly killed.
The authorities have sought to downplay the scale of the violence.
It has been difficult to obtain information from the country or verify the death toll, amid a nationwide internet shutdown in place since election day.
Wearing a red headscarf and dark glasses, Samia took her oath of office at a ceremony attended by regional leaders and dignitaries, including the presidents of Somalia, Zambia, Mozambique, and Burundi.
Kenya sent its Deputy President Kithure Kindiki.
State broadcaster TBC had earlier said the public would not attend the event.
In her victory speech on Saturday, Samia said the poll was “free and democratic” and described the protesters as “unpatriotic”.
Opposition leaders and activists say hundreds were killed in clashes with security forces.
