Gunmen kill at least 31 people in Nigerian city

KANO, Nigeria (AFP) - Gunmen killed eight people in Nigeria's troubled city of Potiskum Saturday, raising the death toll to 31 for three days of violence in the northeastern town, police and residents said.

The body of a school principal was found near his house on Saturday, after seven people had been reportedly slaughtered in the city and 23 earlier killed following blasts and shootings on Thursday.

In the eastern state of Adamawa, the bodies were found of nine people who residents charged were executed by soldiers hunting suspects in a roadside bomb blast four days earlier.

Suspected members of the Boko Haram Islamist group shot dead seven people, including a retired customs chief and an ex-police officer early Saturday, police said.
