Guineans flocked to the polls Sunday to choose their president, shrugging off deadly pre-election violence though the opposition vowed to dispute the outcome.
Incumbent President Alpha Conde, the country's first democratically elected president who is tipped to win a second term, led appeals for calm after around a dozen people were killed in deadly clashes between rival camps on Thursday and Friday.
The opposition is claiming the elections are neither free nor fair, raising fears of post-vote unrest. Ballots in 2010 and 2013 were marred by violence and accusations of fraud.
Speaking after voting in the capital, Conde said: "I ask all Guineans, whatever their party, to fulfil their civic duty peacefully and calmly."
Polls were to close for the nation's six million voters at 1800 GMT, but national electoral commission officials announced on Sunday a two-hour extension where necessary. Results of the first round are not expected until at least Tuesday.
