The attack occurred overnight from Friday to Saturday when “armed individuals carried out an incursion” into the northern town of Solhan, a security source said.
“The figure, which is still provisional, is about 100 dead, men and women of different ages,” said the source.
The government confirmed the attack and the death toll.
The assailants attacked around 2:00 am (0200 GMT) against a position of the Volunteers for the Defense of the Fatherland (VDP), an anti-jihadist civil defense force that supports the national army, before attacking homes and carrying out “executions”. said a local source.
The VDP was established in December 2019 to help Burkina’s ill-equipped military fight jihadists, but has suffered more than 200 deaths, according to an AFP tally.
Volunteers undergo a two-week military training and then work alongside security forces, usually performing surveillance, intelligence gathering or escort duties.
“In addition to the high number of human victims, the worst registered to date, houses and the market were burned,” said another security source, expressing concern that “the still temporary figure of 100 dead may increase.”
The authorities have declared three days of national mourning, ending Monday night at 11:59 pm.
Sohlan, a small community about 15 kilometers from Sebba, the main city in Yagha province near the Mali border, has been hit by numerous attacks in recent years.
On May 14, Defense Minister Cheriff Sy and senior military officials visited Sebba to assure people that life had returned to normal after a series of military operations.
The massive attack by suspected jihadists came hours after another attack on Friday night in the village of Tadaryat in the same region, where at least 14 people were killed.
Since 2015, Burkina Faso has struggled to fight the increasingly frequent and deadly jihadist attacks from groups such as the Group in Support of Islam and Muslims (GSIM) and the Islamic State in the Greater Sahara (EIGS).
The attacks began in the north near the Malian border, but have since spread to other regions, particularly to the east.
Around 1,300 people have died and more than a million have fled their homes.
