A group of angry protesters have gathered outside the Independent National Electoral Commission (Inec) in Nigeria’s capital, Abuja to denounce the results of the election.
They are carrying placards alleging votes have been stolen.
Tension is growing in Nigeria, three days after Nigerians voted in an election marred in parts by violent disruptions and ballot box snatching.
Opposition parties have called for a fresh election in some areas, alleging that Inec has bungled the poll.
The electoral body denies the allegations.
