Thirty-seven civilians were killed and more than 60 wounded when gunmen ambushed a convoy transporting workers of Canadian gold miner Semafo in eastern Burkina Faso, regional authorities said on Wednesday.
The attack is the deadliest in recent years as the military struggles to contain violence that has overrun parts of Burkina Faso, located in West Africa. Semafo tightened security last year following armed incidents near two of its mines in the country.
