At least 24 people were killed during an ethnic violence that engulfed remote town of Wukari in Nigeria's northern state of Tarab, officials said today.
The clash between Jukun and Hausa/Fulani ethnic groups yesterday also left several persons injured, local hospital sources said.
The town has been placed under a 24-hour curfew by the state government to forestall further violence.
More than 20 people were killed in a similar confrontation in February.
Nigeria's population stands at 150 million and their are more than 250 ethnic groups.
