Rights groups in Burkina Faso have accused the army of killing more than 40 people in the north of the country.
The Collective Against Immunity and Stigmatisation of Communities said there had been many cases of kidnapping followed by summary executions.
It said the victims’ bodies had been found on the road between Taffogo and Bouroum blindfolded with their hands tied.
Another rights group, the Observatory of Human Dignity, said most of the victims were Fulani – a mainly Muslim ethnic group of semi-nomadic herders.
Burkina Faso’s military has denied repeated accusations of rights abuses.
The incident is said to have taken place early this month in the village of Taffogo in Tougouri.
Burkina Faso’s army has been fighting an insurgency of groups suspected to have links with al-Qaeda or the Islamic State group, that has claimed more than 2,000 lives and forced some 1.9 million people to leave their homes.
