Campaign beset by violence with supporters of rival candidate Bobi Wine teargassed and detained

Ugandans are preparing to vote in an election that is expected to result in Yoweri Museveni extending his nearly four-decade grip on power in the east African country, after a campaign beset by violence.

Security forces have frequently clamped down on supporters of Museveni’s main opponent, Bobi Wine, by teargassing and shooting bullets at events and detaining people. Authorities have also arrested civil society members and suspended rights groups. On Tuesday, they shut down internet access and limited mobile phone services countrywide.

The actions have prompted fears of unrest around the polls, similar to the violence that followed the general election in Tanzania in October when hundreds of people were killed.

Observers say the government’s reaction shows the ruling party, the National Resistance Movement (NRM), is facing its biggest test yet, and the election risks further dividing Uganda.
