After French troops began leaving the region, military regimes in Niger, Mali and Burkina, struggling with jihadist violence, hardened their positions and joined forces in an Alliance of Sahel States.

Last month, armed attackers stormed military posts, prisons and police stations in another ECOWAS member Sierra Leone, in what the government called a coup attempt that killed 21 people.

A week later Guinea-Bissau also denounced an attempted coup, with fighting between the national guard and special forces of the presidential guard.
