The ambush marks one of the deadliest attacks inside Burkina Faso, which is part of the growing jihadist violence inside the country.
Today’s claims of responsibility are the first for the group in Burkina Faso since 2016.
The Islamic State has officially recognized a loyalty oath sworn by Abu Walid al Sahrawi, a jihadist based in West Africa. Sahrawi first swore his fealty to Abu Bakr al Baghdadi in May 2015. It is not clear why it took so long for the so-called caliphate to recognize him as one of its representatives.
The Islamic State in the Greater Sahara (ISGS) has claimed its second attack in two months. Both reportedly occurred in the same area of northern Burkina Faso near the border with Mali.
