The main opposition leader in Uganda, Kizza Besigye, has rejected the result of Thursday’s elections, in which President Yoweri Museveni won a fifth term of office.
Mr Besigye, under house arrest since Friday, said Ugandans had seen “the most fraudulent electoral process”.
He described the poll as a sham and a creeping military coup.
President Museveni, in power for 30 years, received nearly 61% of the votes, with Mr Besigye taking 35%.
Foreign observers say the poll was conducted in an atmosphere of fear and intimidation.
While praising the “remarkable determination” of Ugandans to vote, EU chief observer Eduard Kukan said the governing National Resistance Movement’s “domination of the political landscape distorted the fairness of the campaign”.
The election has been marred by sporadic violence and opposition allegations of electoral fraud, with social media sites and messaging apps blocked.
