Nigeria has in recent times suffered renewed attacks by Boko Haram terrorists and bandits in Borno, Southern Kaduna, Katsina, Taraba, Niger, Plateau, Yobe and Sokoto states.
A statement on the State Department website Tuesday, quoted the US as asking the Federal Government to hold the culprits to account and protect civilians.
The statement read, "We condemn the recent senseless and brazen killings of civilians in Northern Nigeria.
"In recent weeks, suspected ISIS West Africa militants launched multiple attacks in Borno State, killing more than 120 civilians including women, children, and the elderly. On June 9, unidentified armed bandits attacked a village in Katsina State, killing dozens.
"These horrific crimes follow the shooting of a pastor and his pregnant wife on June 1 and the killing of an imam, local village head, and several civilians on June 5 in the course of inter communal violence in Taraba State.
"The United States calls on the Government of Nigeria to do more to strengthen ongoing efforts to address this violence, hold those responsible accountable and protect civilians."
