Attack in Kodyel village in Komandjari province leaves at least 30 people dead, including children.
More than 17,500 people in Burkina Faso have been forcefully displaced from their homes in the past 10 days due to a series of attacks by unidentified armed groups that have killed 45 people, the UN refugee agency (UNHCR) said.
Attacks by armed groups linked to al-Qaeda and the Islamic State in the West African Sahel region have been rising sharply since the start of the year, particularly in Mali, Niger and Burkina Faso, with civilians bearing the brunt.
A UNHCR statement on Friday said gunmen had carried out a series of attacks in three separate regions, burning down houses and shooting civilians dead. The assailants also ransacked health centres and damaged homes and shops.
“Clearly one of the reasons is to cause mayhem and to torment civilians,” UNHCR spokesman Boris Cheshirkov told a briefing in Geneva.
The security situation in the Sahel region is fuelling one of the fastest growing displacement crises in the world, he said.
Security sources told Reuters news agency on Monday that armed assailants had killed about 30 people in an attack on a village in eastern Burkina Faso.
Last week, two Spanish journalists and an Irish citizen were killed in an ambush by suspected rebels during an anti-poaching patrol near a nature reserve in eastern Burkina Faso.
“The trends we see only point to more violence to come,” Cheshirkov said.
Burkina Faso’s ill-equipped army has struggled to contain the spread of violence.
Last year the government enlisted the help of volunteer militiamen to help the army but they have incurred retaliation by the rebels who attack them and the communities they help.
Armed groups have driven religious and ethnic tensions between farming and herding communities in Mali, Burkina Faso and Niger to boost recruitment among marginalised communities.
The worsening violence in the wider Sahel region has led to one of the world’s most acute humanitarian crises, UN agencies said last week.
The violence in Burkina Faso has displaced more than 1.14 million people in just over two years, while the poor arid country is also hosting some 20,000 refugees from neighbouring Mali who are seeking safety from violence.
