Mozambique's opposition parties say they reject the victory of the ruling Frelimo party, alleging voter fraud in the southeastern African nation's elections.

On Friday, election officials announced that Frelimo won the election with about 57 percent of the vote.

The official opposition, Renamo, which won just over a third of the vote, called for negotiations with Frelimo saying a coalition government should be formed before another election can be held.

The country's third largest party, the Mozambique Democratic Movement, also said the elections were not free and fair despite endorsements by international observer missions. The party called for an investigation into fraud allegations at various polling stations.

Frelimo's victory means that the party's presidential candidate Felipe Nyusi, who was relatively unknown before campaigning began, will be Mozambique's next president.
