Over 100 people were killed in an explosion at an industrial gas plant, Chikason Group Gas plant, in Nigeria, the media reported on Friday.
A truck exploded while it was off-loading butane cooking gas in the town of Nnewi in Anambra state, BBC reported.
AP reports said remains of 100 bodies, including factory workers and neighbours, have already been found.
The dead and injured were taken to the Nnamdi Azikiwe University Teaching Hospital in Nnewi.
A witness told the Vanguard newspaper the blast was triggered when the truck began discharging cooking gas without waiting for the mandatory cooling time.
Witnesses say the explosion caused a huge fire that firefighters and residents took several hours to put out.
A witness to the carnage, Emeka Peters, said: "The fire exploded like a bomb, and the whole gas station went up in thick, black smoke amidst an explosion from cooking gas cylinders. Many people were killed, and most of them were those that had been in the station queuing all day to get their cylinders refilled...Many of them were burned beyond recognition, and I doubt if many family members of the dead victims would be able to identify the remains of their loved ones."
