The incident happened in the early hours of Tuesday when two tankers collided before exploding in the state.
Six persons have been killed in a tanker explosion at Lapai in Lapai Local Government Area of Niger State.
This was confirmed to Channels Television by the Director-General of the State Emergency Management Agency, Ahmed Inga via the telephone.
Mr Inga said at the time of filing the report he and his men were on their way to Lapai.
Those injured in the explosion are said to have been taken to various hospitals in the local government area.
Six tankers and yet-to-be-identified number of smaller vehicles have also been razed by fire.

For over three weeks, the Lambata-Lapai-Bida road has witnessed heavy traffic, with over a thousand tankers and trailers caught in gridlock.
Mr Mahmud Abdullahi, a former spokesman to the Late former Governor Abdullahi Kure, also told Channels Television that the bad condition of the road which is a federal government road has caused the gridlock.
He said heavy vehicles are stuck on the road stretching over 50 kilometres.
