MAIDUGURI, Nigeria -- Police say gunmen from a radical Muslim sect have attacked a town hall in rural northeast Nigeria, shooting at least 20 people dead.
The attack happened around noon Friday in Mubi in Adamawa state, a town near Nigeria's border with Cameroon.
Local police commissioner Ade T. Shinaba said the attack targeted the hall when a group of Nigeria's Igbo people of the southeast were meeting.
Shinaba blamed a radical Muslim sect known as Boko Haram for the killing.
The sect, which wants to implement strict Shariah law across Nigeria, killed at least 510 people last year alone, according to an Associated Press count.
