There has been an increase in attacks on police in Nigeria ahead of the presidential election on Saturday.
Since the weekend, seven officers have been killed in the south-east of the country, where a separatist movement is seeking autonomy.
The Chief of Defence Staff, Gen Lucky Irabor, has said the security forces have completed preparations for the election, and warned those who tried to disrupt the vote they would get a bloody nose.
Concerns have also been raised about the spread of disinformation ahead of the ballot, with the Centre for Democracy and Development warning of attempts to blacken the reputations of candidates by falsely accusing them of hoarding cash amid the continuing shortage of naira notes.
