In this 2018 photograph released by Mouvement pour le Salut de l'Azawad, Islamic State group commander Abu Huzeifa, known by the alias Higgo, poses in uniform. Mali's army said in a statement late Monday, April 29, 2024, that Huzeifa was killed by Malian state forces. The United States had announced a reward of up to $5 million reward for anyone providing information about him. Huzeifa was believed to have helped carry out an attack in 2017 on U.S. and Nigerien forces in Tongo Tongo, Niger, which led to the deaths of four Americans and four Nigerien soldiers. (AP Photo)
