The Gambia's President-elect, Adama Barrow, has left the country after talks failed to persuade President Yahya Jammeh to step down.
Nigeria's President Muhammadu Buhari flew to Banjul to try to broker a deal but Mr. Jammeh would not relinquish power.
Mr Barrow is now heading to Mali, where he will meet West African leaders attending a summit there.
The former Estate Agent wants to resolve the transitional deadlock so he can be sworn in next week.
President Jammeh's term ends on Thursday.
Meanwhile, the Chief of Defence Staff (CDS) General Abayomi Gabriel Olonisakin has hosted some of his ECOWAS counterparts at the Defence Headquarters, (DHQ) Abuja.
This is part of the efforts to mitigate the political impasse in Gambia following the refusal of President Yahya Jammeh to hand over power to the president elect, Adama Barrow.
While welcoming the participants and ECOWAS officials, General Olonisakin expressed the readiness of regional leaders and military commanders to continue the pursuit of dialogue with the political leaders of Gambia and ensure peaceful transition of power in accordance with the Gambian's constitution.
