Nigeria's electoral commission on Saturday announced a six-week postponement to the presidential elections, citing fears over security and the Boko Haram insurgency.
The chairman of the Independent National Electoral Commission (INEC), Attahiru Jega, said security chiefs advised a delay as troops would not be available because of operations against the militants.
"If the security of personnel, voters, election observers and election materials cannot be guaranteed, the lives of innocent young men and women and the prospect of free, fair and credible elections will be greatly jeopardised," he told reporters.
