Human Rights Watch said that more than 180 bodies were found in mass graves in the town of Djibo in northern Burkina Faso.
The organization said in a report today, Wednesday, that the available evidence indicates that government forces are involved in extrajudicial mass executions, and called on the government to hold those involved in these operations accountable.
The Burkina Faso government, for its part, has informed the human rights organization that it will investigate these allegations.
Defense Minister Mumina Sharif Sai said the killings may have been committed by Islamic militant groups who used army clothing and stolen logistical equipment.
He added, "It is difficult for the population to distinguish between armed terrorist groups, army and security forces."
Burkina Faso has been waging war against militant groups linked to al Qaeda and ISIS since 2017. The conflict, which also affects neighboring Niger and Mali, has killed hundreds of civilians and displaced nearly a million people.
