At least 11 people were killed and three injured when a gold mine collapsed in northern Burkina Faso over the weekend, the West African country’s mining ministry said in a statement on Monday. One local elected official said the disaster was first reported “around 9pm on Saturday”, confirming the preliminary death toll of 11 but adding that they “don’t know exactly how many people were inside” at the moment of collapse. The elected official added that eyewitnesses had seen the mine’s beams fail, triggering a “domino effect” of collapse.
