Malians began fleeing to Burkina Faso in 2012 after their lives were upended by an Islamic insurgency, where it took a French-led military intervention to regain power in several major towns. The fighting has since spread across the border to Burkina Faso, creating the fastest growing displacement crisis in the world. Last month Burkina Faso experienced its deadliest attack in years, when gunmen killed at least 132 civilians in Solhan village in the Sahel’s Yagha province, displacing thousands.
