What is "hamoukar"

Hamoukar (in Arabic: حموكار) is a large archaeological site located in the Jazira region of northeastern Syria ( Al Hasakah Governorate), near the Iraqi and Turkish borders. The early settlement dates back to the 5th millennium BCE, and it existed simultaneously with the Ubaid and the early Uruk cultures. It was a big centre of obsidian production.
