Incumbent President Goodluck Jonathan has won Nigeria's presidential election.
Final figures announced by the Independent National Electoral Commission (INEC) today showed that Jonathan won 22.5 million votes, around 57 percent of votes cast, compared to 12.2 million votes, around 31 percent, for his nearest rival, Muhammadu Buhari.
Jonathan appealed today for an end to "unnecessary and avoidable" postelection violence.
The Red Cross says it believes many people have been killed in clashes with the police in northern, mainly Muslim areas of the country.
Resource-rich Nigeria, Africa's most populous nation, has a history of political corruption and flawed elections.
