Gunmen have killed seven Nigerian police officers since the weekend in the southeast, a police spokesperson said on Tuesday, in the latest violence to rock the volatile region ahead of elections on Saturday.
Widespread insecurity is among the top concerns for Nigerians as they head to the polls to elect new members of parliament and a successor to President Muhammadu Buhari.
In the southeast, violence by armed gangs and suspected separatist groups has killed dozens of people this year while electoral commission offices, police stations and government buildings have also been attacked.
