Guinea’s opposition leader, Cellou Dalein Diallo, has declared himself winner of Sunday’s presidential election despite the fact official results have not yet been announced.

The electoral commission says vote counting is still ongoing and that it is the only body mandated to announce the winner.

But earlier, Mr Diallo had told journalists and his supporters that he won the first round despite “anomalies”.

Mr Diallo’s supporters who took to the streets to celebrate were dispersed by police. He later tweeted that three people had been killed and several others injured by the police.

Guineans had protested for months following the decision by President Alpha Condé to run for a third term.

Results of the tensed election are expected by Wednesday after which candidates have eight days to appeal.

Presidential candidates need more than 50% of the vote for an outright victory, or there will be a second round on 24 November.
