Voters in Ghana are choosing between incumbent President John Mahama and challenger Nana Afuko-Addo in what the BBC describes as a close race. The election includes a parliamentary contest.
The BBC reports that most concerns Friday were related to a slow-moving voting process but there were few reports to suggest the vote was anything but peaceful.
Election commission leader Kwadwo Afari-Gyan told the BBC, at worst, voting would extend into the weekend.
"If everything is normal and goes smoothly, we give ourselves 72 hours (to announce the result)," he said.
A second round of voting is scheduled for Dec. 28 should no candidate emerge with a majority. At least 5,000 soldiers are on standby in the event of violence.
Ghana's economy is being revitalized by recent oil discoveries there.
