Nigeria's presidential and parliamentary elections have been delayed for a week.
The Independent National Electoral Commission (INEC) made the announcement just five hours before the polls were due to open on Saturday.
"Proceeding with the election as scheduled is no longer feasible," commission chairman Mahmood Yakubu said, citing logistical issues.
The vote has been rescheduled for Saturday 23 February, reports BBC.
The announcement came after an emergency meeting at the INEC headquarters in the capital, Abuja.
