Since civilian rule was restored in Nigeria five years ago, some 10,000 people have been killed in violence between rival ethnic and religious groups.
In 2001, Tivs and Jukums clashed. Many died and thousands fled their homes. More than 200 people were killed when the army went on the rampage in the town of Zaki Biam after 19 soldiers were killed by a Tiv militia.
Three years on, BBC News Online speaks to elders of the two communities to see what they have learnt from the clashes.
