Tongo Tongo (French pronunciation: [tɔ̃ɡo tɔ̃ɡo]) is a village in the rural commune (municipality) of Tondikiwindi (also Tondi Kiwindi), Ouallam Department, Tillabéri Region in southwestern Niger, 174 km north of the nation's capital Niamey and 28 km south of the border with Mali.

There are no roads, only trails that connect to nearby villages such as Siwili, Firo, Sabara Bangou, Sinka Koira, Gollo, Gouré Tonndi, Kokorobé Koukou, and Zerma Daré.

The physical environment is in an advanced state of degradation caused by habitat destruction, poaching, and the vicissitudes of the local climate.

While scouting the route, the group came under attack by more than 50 enemy fighters, riding in a dozen vehicles and on about 20 motorcycles, firing from numerous directions with small arms.

US Africa Command communicated that the soldiers killed were Staff Sergeants Bryan Black (35) of Puyallup, Washington, Jeremiah Johnson (39) of Springboro, Ohio, Dustin Wright (29) of Lyons, Georgia, and Sgt.

US Africa Command acknowledged the loss of elite US forces would trigger a review of how the US military carries out operations but did not suggest any move to scale back the American mission in Niger.
