The Alliance of Sahel States (AES) - comprising Burkina Faso, Mali, and Niger - has officially launched a joint military force, hailed by junta leaders as a landmark step toward deeper integration and self-reliant defence against jihadist insurgencies destabilising the region.

Mali’s military ruler, General Assimi Goïta, presided over the ceremony at a Bamako airbase, attended by defence ministers, ambassadors, and international representatives. Burkinabé General Daouda Traoré was appointed commander of the force, with headquarters established in Niamey, Niger.

The 5,000-strong force, first announced in January by Niger’s defence minister, is designed to enable coordinated interventions against security threats. Officials reiterated: “We will intervene together.”

The AES was formed after the three juntas withdrew from ECOWAS, accusing the bloc of imposing “inhumane” sanctions following their coups and prioritising foreign interests over citizens. Beyond military cooperation, the alliance seeks deeper economic and political ties, including a planned confederation.

All three countries face escalating Islamist violence from al-Qaeda and Islamic State affiliates, which has displaced millions and strained fragile governments. The launch underscores defiance of Western influence—France has withdrawn troops, while Russia has stepped in through Wagner/PMC support—signalling a regional realignment post-ECOWAS exit.

Informed observers view the move as a symbolic assertion of sovereignty but caution that operational cohesion may be challenged by resource constraints and logistical hurdles.
