LAGOS, Nigeria (AP) — An attack by an armed group on a military base in northern Burkina Faso has left about 50 soldiers dead, according to accounts by a community leader and a resident on Tuesday. The Jama'at Nasr al-Islam wal-Muslimin group, or JNIM, was suspected of carrying out the attack Monday on the base in Dargo in Boulsa province in the northern region of the landlocked West African nation. The two sources, who spoke to The Associated Press on condition of anonymity because they feared repercussions from the military, said about 100 militants participated in the attack, and that the gunmen burned and looted the base after the killings. The military government has yet to publicly acknowledge the attack. JNIM, one of several armed groups conducting attacks across West Africa, has been blamed for hundreds of civilian and military deaths. Burkina Faso is witnessing a surge in attacks by armed groups who are in control of most of the country, especially outside of the capital. The deteriorating security situation has led to political shifts in the country and served as the pretext for back-to-back coups. The military leader, Ibrahim Traore, has been unable to rein in the Islamist groups despite his redrawing of political and military allies.
