Ugandan President Yoweri Museveni won a decisive re-election victory on Saturday, elections officials said, but his main rival Bobi Wine alleged widespread fraud and said citizens should reject the result. Museveni won 5.85 million votes, or 58.6 percent, while main opposition candidate Wine had 3.48 million votes (34.8 percent), the electoral commission said at a news conference on the final results from Thursday's election. The United States and an African election monitoring group complained of election irregularities and Wine, a 38-year-old singer-turned-lawmaker who had rallied young Ugandans behind his call for political change, called the results a 'complete fraud”. 'It’s an election that was taken over by the military and the police,' he said in a phone interview from inside his home in the capital, Kampala, which was surrounded by soldiers who he said had forbidden him from leaving. 'It further exposes how dictatorial the Museveni regime is,' added Wine, who campaigned to end what he called widespread corruption. 'It's a mockery of democracy.” The army's deputy spokesman, Deo Akiiki, told Reuters that security officers at Wine's house were assessing threats he could face by going out: 'So they might be preventing him in the interest of his own safety.' After the results were announced, many neighbourhoods in normally bustling Kampala were unusually quiet as nightfall approached. Soldiers and police who had patrolled throughout the day remained on the streets in large numbers, witnesses said. Hundreds of the president's supporters rode motorcycles from the election tallying centre to downtown, where people danced with posters bearing the president's face. Museveni, 76 and in power for 35 years, campaigned for another term arguing his long experience in office makes him a good leader and promising to keep delivering stability and progress. Wine, whose real name is Robert Kyagulanyi, galvanised young Ugandans with his calls for political change and pledged to end what he calls dictatorship and widespread corruption. On Friday, Wine said he had video proof of voting fraud and would share the videos as soon as internet connections were restored. The government ordered the internet shut down the day before the election, and the blackout was still in place. Electoral Commission Chairman Simon Byabakama said on Friday that under Ugandan law, the burden of proof rested with Wine. Reuters has not independently verified Wine's claims. No EU or US observers The Africa Elections Watch coalition, which deployed 2,000 observers in 146 districts, said in a statement that they had observed irregularities, including the late opening of most polling stations, missing ballot papers and illegally opened ballot boxes. The African Union and East African Community sent observer teams to the election, but neither group of officials responded to requests for comment about possible irregularities. The European Union and the US did not deploy observer teams, but the US State Department’s top diplomat for Africa, Tibor Nagy, said in a t
