Suspected separatists kill four Nigerian police, two civilians

Suspected separatist militants from the Indigenous People of Biafra (IPOB) and its armed wing, the Eastern Security Network (ESN), killed four Nigerian police and two civilians in a gunfight in the Ngor-Okpala area of Imo State. IPOB has been blamed for numerous attacks on police, local government offices and electoral-agency buildings in the southeastern states where the group demands a separate state for Igbo people. The separatist movement has repeatedly denied that it is behind the attacks.
