Uganda's President Yoweri Museveni held a significant lead in early results from Thursday's presidential election, according to the electoral agency. Figures released Friday morning indicated Museveni secured 76 percent of the votes, based on returns from 45 polling stations across the country. Opposition leader Bobi Wine trailed with approximately 20 percent.

The election took place amidst a tense atmosphere following a campaign marked by violence. Museveni, who has been in power since 1986, is seeking a seventh successive term. Wine, a 43-year-old pop star-turned-politician, alleged "massive" fraud during the election. He did not provide documentary evidence to support his claims, and authorities have not yet responded to the allegations.

Ugandans cast their ballots under an internet blackout, adding to concerns about transparency and fairness. Wine's National Unity Platform (NUP) party reported late Thursday that the military and police had surrounded his house in the capital.

Museveni, now 81, once criticized African leaders who overstayed their welcome in power. His continued pursuit of the presidency has drawn criticism from some quarters, given his earlier stance.

The election results are being closely watched by international observers and regional partners. The outcome will likely have significant implications for Uganda's political landscape and its relations with neighboring countries. The electoral agency is expected to release further results in the coming days.
