West African leaders met on Sunday for talks with the region in a deepening crisis, after four countries fell under military rule and with risks growing from Sahel jihadist conflicts.

After coups in Mali, Burkina Faso, Guinea and Niger since 2020, the Economic Community of West African States bloc also saw member states Sierra Leone and Guinea-Bissau claim attempted coups in recent weeks.

A French military withdrawal from the Sahel, the region along the Sahara desert across Africa is increasing concerns over conflicts spreading south to the Gulf of Guinea states Ghana, Togo, Benin, and Ivory Coast.

“These military coups are not only based on fake narrative and false justifications; they are also a driver of insecurity in the region,” ECOWAS commission president Omar Touray said in a meeting before the summit.

ECOWAS leaders will meet in Nigeria’s capital Abuja for an ordinary summit where they will discuss delayed transitions back to civilian rule for Mali, Burkina Faso, Guinea and Niger.

Nigeria’s President Bola Ahmed Tinubu is the current chair of ECOWAS and US Assistant Secretary of State for African Affairs Molly Phee will also be at the meeting to discuss how to support Niger’s return to democratic rule and Sahel security.

Niger – a key Western partner in the fight against Sahel militants – has demanded French troops based there leave, while the US still has military personnel in the country.

ECOWAS members have imposed tough economic sanctions on the military regime in Niger, whose troops ousted President Mohamed Bazoum in July.

ECOWAS has demanded Bazoum’s immediate return to the presidency, but the military junta has kept him in detention and says it may need up to three years for a return to civilian rule.

Earlier this month, Nigeria said it was asking the Niger regime to free Bazoum and allow him to fly to a third country, as a step to opening talks on lifting sanctions.

But Niger’s military leaders rejected that option and have asked Togo’s President Faure Gnassingbe to act as a mediator.

Before Sunday’s ECOWAS meeting, Niger’s military leader General Abdourahamane Tiani visited Togo on Friday with some of his ministers.

ECOWAS has also left on the table the last option of military intervention in Niger though analysts say that appears increasingly unlikely.

Transitions back to democracy and elections have also been stalled or left uncertain in Mali, Burkina Faso and Guinea.
