Businesses across Nigeria are closed again Tuesday, the second day of a four-day strike called by labor unions to protest a sharp rise in the cost of fuel.
Officials say the strike has had no immediate effect on oil production. Nigeria is the world's seventh largest oil exporter. Still, the strike has helped push oil prices to record highs.
Labor unions called the strike to press their demand that the government reverse a recent 20 percent increase in the price of fuel. Talks between the government and unions remain stalled.
