According to survivors contacted by AFP, more than 100 people on motorcycles and pick-up trucks assaulted the village.

The latest massacre occurred a week after 34 defence volunteers and six troops were killed in an attack by suspected jihadists near Aorema, around 15 kilometres from the province capital of Ouahigouya and 40 kilometres from Karma.
Following that attack, Burkina Faso's military junta proclaimed a general mobilization to provide the state with all necessary means to battle brutal attacks blamed on Al-Qaeda and the Islamic State group.
According to the decree, anybody above 18 and physically fit not in the armed services would be "called to enlist in accordance with the needs expressed by the competent authorities."
The administration has already announced plans to recruit 5,000 additional soldiers to combat the insurgency that has seized the country since 2015.
Burkina's transitional president, Captain Ibrahim Traore, has proclaimed a goal of recapturing the 40% of the country's territory seized by jihadists.
According to non-governmental humanitarian organizations, the violence has killed over 10,000 people and displaced two million more.
