At least 70 people were killed and more injured in northern Nigeria on Saturday when a petrol tanker truck overturned, spilling fuel that exploded, the country's national emergency agency said.

"As of this report, over 70 bodies have been recovered, 56 individuals are injured, and more than 15 shops have been destroyed," the National Emergency Management Authority said in a statement.

"The injured have been transported to hospitals for treatment, while recovery efforts for the deceased are ongoing."

Earlier, Kumar Tsukwam, the Federal Road Safety Corps sector commander for Niger state, said most of the victims were impoverished local residents who had rushed to scoop up the spilled petrol after the truck overturned.

"Large crowd of people gathered to scoop fuel despite concerted efforts to stop them," Tsukwam said in a statement.

Tsukwam said firefighters had managed to put out the fire.
