On October 4, 2017, four U.S. Special Forces service members were killed in an ambush near the western Niger village of Tongo Tongo in an attack that has since gone unclaimed by any terrorist entity.

U.S. military officials believe the attack came from the Islamic State (IS/ISIS) in the Greater Sahara. However, if ISIS did carry out the attack, why didn't it claim it—especially after its claims of responsibility for attacks like Las Vegas and dozens of others which contain no direct connection to it?
