Yes i know it is hard to beleive but currently all petrol stations in that oil rich country are closed due to lack of petrol.Many food distributors to markets cannot make deliveries,workers are grounded as generators for power back up are dead in many offices.The Nigerian govt was subsidising fuel to the locals but the importers have not been paid billions of dollars in accrued debts..yes nigeria imports petrol products.Mobile phone masts will shut down too anytime...curse of the oil perhaps?
