Over 1,000 protesters on Wednesday blocked major highways in the capital city of Nigeria's north-central Benue state Makurdi, calling on the government to end periodic killings by herdsmen.
"These Fulani herdsmen entered communities unprovoked and burned down houses while maiming unarmed Nigerians, especially women and children. How is this a 'herdsman/farmer clash'?"
Yamu said at least eight herdsmen suspected to be behind the latest violence were arrested across the region. He confirmed 17 dead in the violence, although Ortom had said over 20 people were killed.
In a statement on Wednesday, Buhari condemned the violence and called for an immediate crackdown on the attackers.
"One of our pledges to Nigerians is that we will ensure the safety and security of lives everywhere in the country. We will keep this promise. Let me assure that security agencies are working to arrest those behind the regrettable attack in Benue State, and prevent further attacks," he said.
