Nigeria postpones presidential vote over security
The electoral commission in Nigeria has postponed the 14 February presidential election by six weeks over concerns about the security situation.
Commission chief Attahiru Jega said he had been told troops would not be available to help patrol the ballot because they would be fighting Boko Haram militants in the north-east.
The election will now be held on 28 March instead.
President Goodluck Jonathan is facing a strong challenge in the contest.
The postponement is a highly contentious move, the BBC's Will Ross reports from Lagos.
Officials from the main opposition party accuse the military of forcing the electoral commission into the delay to help the sitting president's campaign.
It looks set to be a tight race between Mr Jonathan and the former military ruler, Muhammadu Buhari, our correspondent says.
The postponement may well increase the tension which is already palpable, he adds.
- 8 January: President Jonathan opens his election campaign
- 14 January: Nigerian military repel attack on the town of Biu in the north-eastern state of Borno
- 18 January: Suicide bomber kills four people after detonating a car bomb at a bus station in north-eastern Yobe state
- 25 January: Militants attack strategically important north-eastern city of Maiduguri, with dozens reported killed
- 4 February: Militants kill up to 70 people in attack on Cameroon
- 6 February: First attack on Niger repulsed by Niger's military
"The commission cannot lightly wave off the advice of the nation's security chiefs," said Mr Jega.
"The risk of deploying young men and women and calling people to exercise their democratic rights in a situation where their security cannot be guaranteed is a most onerous responsibility."
Parliamentary elections due to take place on 14 February have also been postponed to 28 March.
Elections for state governors and assemblies slated for 28 February have been moved to 11 April.
Thousands of people have died as a result of the Boko Haram insurgency, while more than a million people have been displaced over the past six years.
The militants control a large stretch of land in north-eastern Nigeria but have also started attacking neighbouring countries.
The group attacked a town in Niger for the first time on Friday.
