The October 4 attack in Niger that claimed the lives of four U.S soldiers – as well as their interpreter and four Nigeriens – remains under official investigation amid a firestorm of controversy and confusion. While the Pentagon has yet to point explicit blame, the Defense Intelligence Agency suspects  the perpretators were ISIS in the Greater Sahel (ISGS). ISGS is headed by prominent jihadist figure, Adnan Abu Waleed al-Sahrawi.
