Four people have been killed in clashes between security forces and supporters of a Cameroon opposition leader, Issa Tchiroma, who claims to have won recent presidential elections.

The clashed erupted ahead of the announcement of official results on Monday, October 27, 2025.

Tchiroma, who challenged President Paul Biya’s 43-year grip on power in the October 12 ballot, had called on his supporters to march peacefully on the eve of the announcement, despite a ban on public gatherings.

Tchiroma says he won 54.8 percent of the vote, but most analysts expect the 92-year-old Biya to win an eighth term in a system his critics say has been increasingly rigged.

In Cameroon’s largest city Douala, the regional governor, Samuel Dieudonne Ivaha Diboua, said demonstrators attacked a gendarmerie brigade and police stations in two districts.
