On Monday, Buhari blamed the escalation of the herders-farmers conflict on politicians who are taking advantage of the crisis for political gains in the upcoming 2019 elections.
Herders and farmers have clashed for years over the battle for resources as roaming herdsmen tend to graze their cattle on farmlands, leading to tension and sometimes violence that leads to deaths of people on both sides.
Ever since herdsmen were blamed for the death of 73 people in attacks launched in Guma and Logo local government areas of Benue State in the opening days of January 2018, hundreds of people have been killed in similar attacks with Taraba and Benue bearing most of the brunt.
