Administratively it belongs to the Nahiya Tell Tamer.

The village is inhabited by Assyrians belonging to the Assyrian Church of the East.{{cite journal |last=Fernandez |first=Alberto M. |author-link=Alberto M.

The people of Waltoo originate from the Hakkari mountains in Turkey. There are 4 different tribes in Walto. Resht D Nara, Nashet D Matha, Khidnaya, and Serta. While these four tribes live in the same town now, back in Hakkari they lived in separate villages in a greater area called The Walto Valley. The Walto valley was a part of Upper Tyari.

In recent years, during the Syrian Civil War, the Assyrian Church of St. Mary had been destroyed by ISIS in April 2015. Before that, on 23rd February 2015, Tell Nasri had been attacked by ISIS and its people fled to both Al-Hasaka and Qamishli seeking refuge.
