International Desk: 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.
The announcement came after an emergency meeting at the INEC headquarters in the capital, Abuja.
Mr Yakubu said the delay would give the commission time to address vital issues, but did not provide further details.
In the past two weeks several INEC offices have been set alight, with thousands of electronic smart card readers and voter cards destroyed.
There have also been claims of shortages of election material in some of the country's 36 states.
There are 73 registered candidates in the presidential election, but campaigning has been dominated by President Muhammadu Buhari, 76, and his main challenger, former Vice-President Atiku Abubakar, 72.
Mr Buhari says he has built a strong foundation for prosperity, but his rival says Nigeria is not functioning.
