On October 4, 2017, 11 US troops and 30 Nigerien forces were ambushed by ISIS-related militants near the Niger-Mali border.
Four US troops were killed, in addition to four Nigerien partner forces, in a battle against overwhelming terrorist forces. The US military awarded six medals to the Nigerien soldiers who fought in the battle, including two Bronze Stars.
A US-led investigation found that US's ISR assets did not have enough fuel to provide cover for American forces, in addition to inadequate rest for the troops. Roughly an hour and a half after the battle began, two French fighter jets responded by driving the enemy forces away.
