A witness in northeastern Nigeria says 11 people have been killed in fighting between nomadic cattle herders and farmers.

The fighting happened around the village of Ngandum in Adamawa state where homes and farms were burned in violence that erupted Sunday.

Witness Gambo Ibrahim told The Associated Press that he counted 11 corpses in the village on Monday. Adamawa state police spokesman Ibrahim Muhammad confirmed the fighting occurred and said police were investigating.

Fighting between cattle herders and farmers often happens across Nigeria, as herders will allow their animals to graze on land and eat crops belonging to farmers. Herders also routinely attack and kill those who harm their cattle.
