Shockwaves are spreading across Africa after U.S. President Donald Trump ordered airstrikes on ISIS-linked targets in northern Nigeria — triggering rising fears of regional destabilization. Neighbouring Niger has now approved sweeping mobilisation powers, allowing rapid military escalation, citizen requisitions, and emergency security measures. The decree comes as Niger, Mali, and Burkina Faso formally activate a new joint counterterrorism force, while Niger’s Russia-leaning military leadership distances itself from Western partners. With the U.S. strike zone bordering Niger, authorities are bracing for spillover violence — raising alarms across the Sahel.
