Nigeria to launch crucial elections

Africa's most populous nation will be voting in presidential and parliamentary elections on Saturday.

Nigeria's Muhammadu Buhari is running for president again.

More than 84 million people are registered to vote for the president, 109 senators and 360 members of the House of Representatives. Two weeks later, voters will be asked to come out again to choose governors and members of state parliaments.
