Nigerian Election Extended Til Sunday in Some Areas
Elections in parts of Nigeria have been extended until Sunday after delays and a number of attacks.
The delays were “not widespread” but were still “a matter of concern”, an election official told the BBC.
Technical problems with new biometric cards slowed down voter registration, even affecting President Goodluck Jonathan.
More than 20 people have reportedly been killed in various attacks by unknown gunmen.
Mr Jonathan is facing a strong challenge from Muhammadu Buhari.
The election is said to be the most closely fought since independence.
