Amadou Kouffa, the leader of JNIM’s Katibat Macina, has been designated as a global terrorist by the US State Department.

On June 15, the Islamic State’s West Africa province released a video featuring a masked jihadist known as Abu Salmah al-Mangawi. Along with foot soldiers in Burkina Faso and Mali, al-Mangawi renewed his pledge of allegiance to Abu Bakr al-Baghdadi.
The jihadist group also claimed an assault on a high-security prison near the capital of Niamey.
The Islamic State issued several claims of responsibility for attacks by the group known as the Islamic State in the Greater Sahara (ISGS) in Mali, Burkina Faso and Niger.
