Nigeria's President Muhammadu Buhari has called on Nigerians to stop their "unruly behaviour" to achieve progress.
In an address to mark 55 years of independence from British rule, he said Nigerians would have to "face squarely" the economic crisis caused by the sharp fall in oil prices.
It would require "prudent house-keeping", and tackling corruption in the oil sector, Mr Buhari added.
It was his first address to the nation since becoming president in May.
