Many were feared dead in Kano on Tuesday as explosion rocked the Sabon Gari area of the capital city.
Details of the blast and its cause are still sketchy but visuals from the scene show that it affected some buildings and left several injured including school children.
The visuals also confirm that the blast might have claimed several lives with at least one corpse seen on the floor.
A crowd had gathered right after the blast with some people trying to help the injured and others lamenting the damage.
Initial visuals from the explosion site showed several schoolchildren being moved away from the scene. One of them was injured. This led to speculation that the explosion occurred in a school.
But the Kano State Government has said it happened in a facility opposite a school.
The Commissioner for Information in the state, Muhammad Garba, said in a statement the blast happened at an animal feed store opposite the school.
He called on people in the state, particularly those living in the area where the incident occurred to remain calm while the government works with relevant agencies on the matter.
Garba cautioned the public against spreading unsubstantiated news and gave the assurance that the government would keep the public updated on any development on the matter.
