West African leaders flew out of Banjul late on Friday with The Gambia’s president-elect Adama Barrow, en route to Mali for crisis talks with regional heavyweights in hopes of ending the nation’s political impasse. Nigerian President Muhammadu Buhari led a three-nation delegation to Banjul earlier in the day, which his foreign minister admitted had not succeeded in getting longtime Gambian President Yahya Jammeh to step down.
