Nigeria, Africa’s top oil producer, is experiencing an acute shortage of fuel, which is causing huge disruption across the country. People are waiting at petrol stations for several hours, some into the night trying to get fuel. The BBC reports that the longest queues have been in cities like the capital, Abuja, and the commercial hub of Lagos, at those petrol stations that actually have some fuel in stock. Meanwhile, controversy over the government’s plan to scrap subsidies on petroleum products has reportedly also caused bottlenecks in supplies.
