President Samia Suluhu Hassan has been declared the winner of Tanzania's presidential election, securing another term amid days of unrest across the country, BBC reported.

Samia won 98% of the votes in Wednesday's poll, the electoral commission said. In her Saturday victory speech she said the election was "free and democratic", accusing protesters of being "unpatriotic".

Opposition parties rejected the results, calling the vote a mockery of the democratic process as Samia's main challengers had been either imprisoned or barred from running, according to BBC.
