Heads of state from Burkina Faso, Chad, Mauritania, Mali and Niger are meeting at this year’s G5 Sahel Summit in Niamey, Niger’s capital.
While the operation of their joint regional counter terrorism force will be top of the agenda, they’ll also discuss other issues including regional development and the rotational presidency of the grouping, which is currently held by Niger.
The $500m (£360m) budget target for the G5 Sahel Force has nearly been met, although it is still not clear how this will be spent.
The force carried out its first operation last October and its second last month.
It is expected to collaborate with French and UN forces in the region to try and bring stability in the wake of instability from jihadi militants in the Sahel.
