Mali’s junta announced Sunday that it will quit the West African G5 Sahel security force after it was blocked from assuming the presidency of the regional group, deepening its isolation after its neighbours hit it with sanctions in January over perceived foot-dragging in restoring civilian rule. The AFP news agency reports that in a May 11 report to the Security Council, UN Secretary-General Antonio Guterres said Mali’s vague transition timeline was hampering the G5 anti-jihadist force’s ability to function and called for the return to civilian rule as soon as possible.
