In Nigeria, at least 14 people were reportedly killed in a stampede during a campaign rally of President Muhammadu Buhari in capital Abuja. Local media said panic broke out at the end of the gathering inside the Adokiye Amiesimaka Stadium, ahead of the general election scheduled on Saturday.
Saturday's election in Africa's most populous country will see Buhari stand for a second
four-year term against former vice-president Atiku Abubakar in what is expected to be a close race.
In recent weeks, tensions have risen between the APC and Abubakar's People's Democratic Party (PDP). The US, Britain and the European Union have expressed concern over Buhari's suspension of Nigeria's top judge last month.
