Nigeria’s presidential hopefuls voted Saturday amid logistical issues and insecurity. Atiku Abubakar, the candidate of the main opposition party the People’s Democratic party, cast his ballot in Yola, eastern Nigeria. Peter Obi, the candidate of the Labour Party, cast his ballot in Anambra, south-east Nigeria. The vote is being carefully watched as Nigeria is Africa’s largest economy and one of the continent’s top oil producers. The official results for turnout are highly expected.
