At least 24 people were injured when members of Guinea’s rival political parties began throwing rocks at each other after a campaign event, said a party official and a doctor at the hospital where the injured were being treated.

Guinea’s run-off election to choose the country’s next president has been delayed to August 1 because the country’s supreme court says it needs more time to probe fraud complaints.

Guinea is holding its first free election today since independence more than half a century ago - a vote many hope will finally end decades of harsh military rule and launch a new democratic era.
