Four people have been killed in an explosion at a local radio station in the central Nigerian state of Kogi.
It is unclear whether the attack was perpetrated by Boko Haram or organised robbery and kidnapping groups that operate in West African countries.
"Three security guards and an engineer working for the station were killed. We are investigating who could be responsible and why," public relations officer Shola Adebayo said to Reuters.
Adebayo said police believed Ta'o FM was the target. “The attack on Ta’o FM started at about 7 pm when we began to hear a series of gunshots and everyone began to scamper to safety before the blast went off.
After the explosion everything became quiet. It was later that we heard that four persons within the FM station got killed and several others were injured.
I saw many injured people being helped to the hospital by volunteers, most of them were soaked with blood,” said Medinatu Ajayi, a resident of Kuroko.
While Kogi city is a way off from northeastern Nigeria, where Boko Haram has waged a six-year insurgency, the region has also experienced intermittent attacks by robbery and kidnapping rings.
The incident is known as the first of such bombings in that part of Kogi state.
