Nigeria’s President, Muhammadu Buhari says he has done his best to surmount the country’s economic and security challenges.

A statement by the president’s Senior Special Assistant on Media and Publicity, Garba Shehu, said Buhari spoke when he received some governors of the All Progressives Congress (APC) at his country home in Daura, Katsina state on Thursday.

Buhari insisted that things were worse when he assumed power as a democratically elected president.

He, however, added that the country’s security situation had improved compared to the instability in the North-East before 2015 when parts of the region were directly under terrorists’ control.

“The subsequent development in the North-West is the most amazing, where people who lived together, spoke (the) same language and shared common faith started killing each other and rustling cows.

“I had to change the security chiefs and we had to get down to the fundamentals of providing security. If you look at the situation in relation to time and resources, you will find out what we have been able to achieve’’.

Buhari said oil prices fell from more than $100 to less than $38 under his watch, with crude oil output at 2.1 million barrels a day dropping to about 500,000 barrels, hindered his government efforts to turn the country’s economy around.
