Tell Nasri (Arabic: تل نصري), also known as Walto[1] [2] Arabic: ولطو), is a village near Tell Tamer in western al-Hasakah Governorate, northeastern Syria. Administratively it belongs to the Nahiya Tell Tamer.
The village is inhabited by Assyrians belonging to the Assyrian Church of the East.[3] At the 2004 census, it had a population of 650.
