Tanzanian President Samia Suluhu Hassan has been sworn in for a second term amid tight security, following an election marred by violent protests and rejected by the opposition as a sham, BBC reported.

The inauguration ceremony was held at a military parade ground in the capital, Dodoma, instead of a stadium as in previous years. It was closed to the public but was shown live 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, according to BBC.
