Although votes in Nigerian election are counted final results may take days
Vote counting is under way in Nigeria's tightest presidential election since military rule ended in 1999. Turnout appeared to be high, with many young, first-time voters arriving before dawn to cast their ballots.
Saturday's voting was marred by long delays at polling stations, as well as scattered reports of ballot box snatching and attacks by armed men. And some parties have raised alarm over allegations of irregularities, which could lead to a disputed outcome.
