Homes and the local market were burned during the raid on Solhan in the early hours of Saturday morning.

No group has said it was behind the violence, but Islamist attacks are increasingly common in the country, especially in border regions.

The UN chief said he was “outraged” by the incident.

António Guterres “strongly condemns the heinous attack and underscores the urgent need for the international community to redouble support to member states in the fight against violent extremism and its unacceptable human toll,” his spokesperson said.

On Sunday, a total of 160 bodies were recovered from what local officials in Solhan described as three mass graves, AFP news agency reported.

The number of people killed in Solhan has increased from earlier reports of about 132 deaths, and there are concerns that the death toll may rise further.

Following the news of Saturday’s attack, the Burkinabe President Roch Kabore declared three days of national mourning, writing in a tweet that “we must stand united against the forces of evil”.

He described the attack as “barbaric” and said that security forces were trying to track down the perpetrators.

In another attack on Friday night, 14 people were reported to have been killed in the village of Tadaryat, about 150km (93 miles) to the north of Solhan.

Last month, 30 people died in an attack in the east of Burkina Faso.

The country is facing a deepening security crisis, like many of its neighbours, as armed groups carry out raids and kidnappings across much of the region.
