ABUJA (Reuters) - Nigeria's President Muhammadu Buhari condemned a spate of killings in different parts of the country and ordered an investigation into a raid by gunmen that killed 17 people on Monday night.
The motive for the attack on a market in the central region of Benue was unclear. It added to a long list of security challenges: an insurgency in the northeast by jihadist group Boko Haram; violent clashes between nomadic herdsmen and farming communities over grazing rights in the middle of the country; and attacks by militants on oil facilities in the Niger Delta.
