Tanzania’s President Samia Suluhu Hassan has been sworn in at a low key ceremony with limited invited guests, following a disputed election that sparked deadly protests after two main opposition candidates were barred from running.

The ceremony was held on government-owned grounds in the administrative capital of Dodoma, a departure from the past, when president took the oath at packed football stadiums that were open to the public.

Tension remains high in the commercial capital, Dar es Salaam, following three days of election protests. Gas stations and grocery shops were closed to empty streets as government employees continued to work from home.

The Oct. 29 election was marred by violence as demonstrators took to the streets of major cities to protest the poll and stop the counting of votes. The military was deployed to help police quell riots. Internet connectivity has been on and off in the East African nation, disrupting travel and other activities.

The protests spread across Tanzania, and the government postponed the reopening of universities, which had been set for Nov. 3.

A spokesman for the U.N. human rights office, Seif Magango, on Friday told a U.N. briefing in Geneva by video from Kenya that there were credible reports of 10 deaths in Dar es Salaam and Shinyanga and Morogoro towns.

Main opposition party, Chadema said “These results have no basis in reality, as the truth is that no genuine election took place in Tanzania,” the party’s statement read in part.

Chadema party leader Tundu Lissu has been imprisoned for several months after being charged with treason for calling for electoral reforms that he said were necessary for a free and fair vote. Another opposition figure, Luhaga Mpina of the ACT-Wazalendo Party, was barred from running.

The event was attended by presidents of Mozambique, Zambia, Burundi, and Somalia. President Ruto of Kenya was represented by his vice.

The election violence in Tanzania led to a closure of the border crossing with Kenya at Namanga, where agricultural goods in trucks have been rotting for six days.
