Twenty people were killed in an attack by suspected jihadists on a gold-mining site in northern Burkina Faso, sources said.
Gunmen came to Dolmande site in Soum province and fired on people working there, killing 20, a security source said on condition of anonymity.
A local source said around 20 people were killed in the attack, but gave no further details.
There was no immediate comment from Burkinabe authorities.
Once a pocket of relative calm in the Sahel, Burkina has suffered a home-grown insurgency for the past three years, amplified by a spill-over of jihadist violence and criminality from Mali.
Friday’s bloodshed extends recent violence including the death of 29 people in attacks on a food convoy and a transport truck in September.
