President Muhammadu Buhari has condemned the attack on three communities in Íshíelu Local Government Area of Ebonyi State by suspected Fulani herdsmen.
Speaking on Tuesday at Obegu, Umahi said the herdsmen allegedly perpetrated the mayhem carrying AK-47.
He revealed that he knows the sponsors of the herdsmen, vowing to expose them to the authorities.
Also, a former Governor of the Central Bank of Nigeria and a member of the Presidential Economic Advisory Council, Professor Chukwuma Soludo, escaped an assassination attempt during the week.
He was attacked during a town hall meeting in Aguata LGA. Three police escorts were killed.
Reacting in a statement to newsmen on Saturday, President Buhari directed law enforcement agencies to fish out the attackers and make them face justice.
He extended his sympathies to families and friends who have lost loved ones and to the communities in Ebonyi State
Buhari also commiserated with Soludo and the families of the security operatives who lost their lives trying to defend innocent citizens assembled for a peaceful meeting.
He reassured Nigerians that ongoing efforts which had led to the record recovery of illegal weapons and arrests of a large number of arms suppliers would be intensified.
