Gunmen kill at least 15 in Nigeria attack

Many wounded at Christian service in Kano

Gunmen killed at least 15 people and wounded many more on Sunday in an attack on a university theater being used by Christian worshippers in Kano, a northern Nigerian city where hundreds have died in Islamist attacks this year.

Security sources said gunmen arrived on motorbikes and threw small homemade bombs into the theater before shooting fleeing worshippers.
