A convoy of a Canadian mine company, SEMAFO, was attacked by jihadists on its way to its gold mine in Burkina Faso. The convoy left the city of Fada for the village of Boungou and was about 24 miles (40 km) from its destination when a jihadist militia killed 37 people and injured 60. Their military escort vehicle was destroyed up by an explosive device just before the convoy was charged. Attacks have spread from Mali, where extremist groups have become entrenched over the past few years. This is not the first attack on SEMAFO miners in Burkina Faso. Three occurred in 2018, with 12 total deaths. Government troops in Burkina Faso and Mali have been struggling to control terrorist activity. There are two other Canadian mining companies operating in Burkina Faso.
More info at BBC, Canoe and on the mining company's website (see above). There is a photo near the mine location that appears to show the mine operation.
