The victims of Saturday’s explosion are being treated in nearby hospitals, the Emergency Situations Agency said.
A number of similar incidents have occurred in Nigeria in recent months.
Two weeks ago, at least five people were killed when a petrol tanker crashed in oil-rich Delta state. at least 153 people died in an explosion while trying to clean up a gasoline spill in October.
Fuel prices have risen more than 400% in the past 18 months following Nigerian President Bola Tinubu’s bold economic policies, including the removal of long-standing fuel subsidies.
The changes have left millions of people in poverty, with many forced to resort to desperate measures to survive.
The government has stated that its policy is aimed at strengthening the economy.
