Ivory Coasts President Alassane Ouattara has won a controversial third term in office in an election boycotted by the opposition.
He took 94% of the vote, even winning 99% in some of his strongholds.
Turnout was put at almost 54%. The result has to be confirmed by the Constitutional Council.
On Monday, the Ivorian opposition said it was creating a transitional government which would organise a new election.
Main opposition candidates Pascal Affi NGuessan and Henri Konan Bédié had urged their supporters not to vote in Saturdays poll.
They got 1% and 2% respectively, while a fourth candidate, Kouadio Konan Bertin, also got 2%, according to the official results.
Opposition figures say it was illegal for Mr Ouattara to stand for a third term as it broke rules on term limits.
But the presidents supporters dispute this, citing a constitutional change in 2016 which they say means his first term effectively did not count.
The United Nations refugee agency has said thousands of people have fled to neighboring countries, fearing more violence.
At least 35 people have been killed in political clashes, which continued on Election Day.
