President Muhammadu Buhari has emphasised the need for countries in the West African sub-region and those in the Sahel facing security challenges to team up to confront the menace headon.
The President made the call in Abuja, while receiving the new Special Representative of the UN Secretary-General for West Africa and the Sahel, UNOWAS, Mr. Mahamat Saleh Annadif, a Chadian.
Being a neighbour, President Buhari said Annadif had vast experience on matters affecting the Sahel, having served for five years in Mali, and hoped that he would get the countries to work together to confront the issues affecting them.
Describing the problems as enormous, President Buhari noted that Boko Haram had exerted heavy toll in terms of lives and resources in Nigeria and some neighbouring countries, while Mali is equally having a large swathe of the country occupied by militants.
President Buhari pledged the assistance of Nigeria to the Special Representative to enable him succeed in his assignment.
Mr. Annadif had said he had chosen to visit Nigeria shortly after his appointment, because of her crucial role in West African unity.
He said he was quite familiar with the problems of the Sahel region, and would depend on the help of Nigeria to succeed.
