Oil workers have threatened to stage national strike to protest delays in salary payments.
They threatened to go on strike by Friday if they don’t get paid.
Their employers say the government owes them over $2.5bn for bringing petrol into the country, and they say they will not pay salaries until that bill has been settled.
But the Nigerian authorities say some of the claims by these oil companies are fraudulent.
