Cameroon's 92-year-old president has won a controversial eighth term, in a fiercely disputed election.

Paul Biya, who is the world's oldest head of state, won 53.7% of the vote, compared to the 35.2% of opposition leader Issa Tchiroma Bakary, the Constitutional Council declared.

Before the announcement, Tchiroma Bakary - a former Biya ally - insisted he had won the election, but the ruling Cameroon People's Democratic Movement (CPDM) dismissed his claim.

The election, held on 12 October, has been marred with deadly violence, and in recent days, hundreds of Tchiroma Bakary's supporters have defied protest bans in several cities, clashing with security forces.

Biya thanked voters for once again trusting him. He expressed hope that together, they will build a peaceful, united, and prosperous Cameroon.

Protests escalated in Douala, the economic capital, resulting in at least four fatalities, while clashes between supporters and police occurred elsewhere.

The authorities have not yet commented on reports of sniper activity near Bakary's residence, where locals reported hearing gunfire aimed at protesting civilians.

Amidst the turmoil, many in Yaoundé voiced their discontent, fearing for the country's stability under Biya's continued rule.

Voter turnout for the election was recorded at 58%, with various petitions alleging electoral fraud, all rejected by the Constitutional Council.

Critics argue that Biya's lengthy tenure, which began in 1982, has been marked by economic decline, corruption, and limited freedoms. With significant unrest following the election results, experts warn of potential political turmoil ahead.
