Nigeria’s customs authorities have banned the sale of petrol within 20km (12 miles) of the country’s borders.
The controversial move is an attempt to prevent heavily subsidised Nigerian petrol from being smuggled for sale in neighbouring countries.
A Nigerian customs official Joseph Attah told the BBC that petrol stations around border towns have been used to divert millions of litres of petroleum products.
Nigeria has closed its land borders to trade until at least 31 January 2020. Neighbouring countries are angry at the impact the closure is having on their economies.
Many Nigerians are also complaining about rising prices and shortages of staples.
