A joint security force announced by the ruling juntas in Mali, Niger and Burkina Faso aims to combat extremist violence in the Sahel region.The effectiveness of the joint force is doubted by analysts due to various challenges it faces.Details about the operation of the force remain unclear, referred to as an “operational concept” by Brig. Gen. Moussa Salaou Barmou.A joint security force announced by the juntas ruling Mali, Niger and Burkina Faso to fight the worsening extremist violence in their Sahel region countries faces a number of challenges that cast doubt on its effectiveness, analysts said Thursday.Niger’s top military chief, Brig. Gen. Moussa Salaou Barmou said in a statement after meeting with his counterparts Wednesday that the joint force would be “operational as soon as possible to meet the security challenges in our area.”The announcement is the latest in a series of actions taken by the three countries to strike a more independent path away from regional and international allies since the region experienced a string of coups — the most recent in Niger in July last year.NIGER’S JUNTA MAKES MILITARY PREPARATIONS AHEAD OF POSSIBLE INTERNATIONAL INTERVENTIONThey have already formed a security alliance after severing military ties with neighbors and European nations such as France and turning to Russia — already present in parts of the Sahel — for support.

They all share borders in the conflict-hit Sahel region and their security forces fighting jihadi violence are overstretched.JUNTA’S 3-YEAR PLAN TO TRANSITION NIGER BACK TO DEMOCRATIC RULE A ‘PROVOCATION,’ WEST AFRICAN BLOC SAYSThe effectiveness of their security alliance would depend not just on their resources but on external support, said Bedr Issa, an independent analyst who researches the conflict in the Sahel.The three regimes are also “very fragile,” James Barnett, a researcher specializing in West Africa at the U.S.-based Hudson Institute, said, raising doubts about their capacity to work together.”They’ve come to power through coups, they are likely facing a high risk of coups themselves, so it is hard to build a stable security framework when the foundation of each individual regime is shaky,” said Barnett.
