Voting is under way in Ghana’s presidential election in what analysts say is a tight race between President John Mahama and veteran opposition leader Nana Akufo Addo.
All seven candidates have pledged to keep the process peaceful but an opposition supporter died when a rally tuned violent on Monday.
The campaign has been dominated by the faltering state of Ghana’s economy and the issue of corruption.
Results are expected within three days.
A run-off will be held later in the month if neither of the two main candidates secures more than 50% of the votes.
The candidates signed a pact last week vowing to follow electoral rules and keep the peace.
But clashes broke out on Monday in Chereponi, a small northern town on the border with Togo. In addition to the reported death, six people are said to be in a critical condition as a result.
Defeat for Mr Mahama of the National Democratic Congress (NDC) would make him the first incumbent to lose an election since Ghana returned to multi-party democracy.
He has been nicknamed “Mr Dumsor”, a local word that refers to the power cuts that have blighted the country during his term, but on the campaign trial has been trying to convince Ghanaians that he is delivering on his promise of creating more jobs.
Mr Akufo-Addo meanwhile has promised free high-school education and more factories, but his critics have questioned the viability of his ambitions.
