Diban (Arabic: ذِيبَان, romanized: Ḏībān, also spelled Thiban or Zeiban) is a town in eastern Syria, administratively part of the Deir ez-Zor Governorate, located along the eastern bank of the Euphrates River, south of Deir ez-Zor, 17 kilometers south of al-Busayrah and 13 kilometers north of Al-Asharah.[2] Nearby localities include Al Mayadin to the north and west, al-Hawayij to the northeast, Mahkan to the south west and al-Tayanah to the southeast. According to the Syria Central Bureau of Statistics, Diban had a population of 9,000 in the 2004 census. It is the administrative seat of a nahiyah ("subdistrict") which consists of ten localities with a total population of 65,079 in 2004.[1]
Part of Diban is situated on a hill called Tell Diban, which is also an archaeological site. Tell Diban is identified with the ancient Aramean city of Rummunina,[2][3] a probable derivation of the Aramaic word rumman ("pomegranate").[2] The area and its surrounding fields served as a pre-war camp for Assyrian king Tukulti-Ninurta II's army during his last military campaign in 885 BCE. The king reported that Rummunina was situated along a canal of the Khabur River, a tributary of the Euphrates.[3] According to Belgian orientalist Edward Lipinsky, Tell Diban was "certainly occupied during the Iron Age."[2]
On 25 September 2023, 18 local gunmen, three SDF members and a civilian were killed in clashes in the town.[5] The same day, tribal fighters seized the town.[6] On 7 August 2024, additional clashes occurred in the settlement between local tribes and the YPG.[7]
