Those injured in Saturday’s explosion are being treated in nearby hospitals, the emergency management agency said.
Nigeria has seen a number of similar incidents in recent months.
Two weeks ago, a fuel tanker involved in a crash exploded in the oil-rich Delta state, killing at least five people, and at least 153 people died in an explosion while trying to collect leaking petrol in October.
Fuel prices have increased by more than 400% in the last 18 months following bold economic policies by Nigerian President Bola Tinubu, including the removal of long-standing fuel subsidies.
The changes have put millions of people into poverty, with many forced to turn to desperate measures for survival.
The government has said its policies are aimed at strengthening the economy.
