Long-standing tensions between herdsmen and farmers have flared up again in Kaduna state, northern Nigeria, leaving possibly hundreds dead in tit-for-tat violence. Last weekend at least 21 people were killed and several homes were destroyed when suspected cattle drivers attacked five farming communities.But the clashes between the Muslim, largely Hausa-speaking Fulani cattle drivers and the mainly Christian farmers have escalated since December, when a Fulani chief was killed.
