[2] The town was captured by the Syrian Democratic Forces on 14 December 2018 in the Battle of Hajin, after a week and a half of heavy clashes and intense airstrikes by the United States-led Combined Joint Task Force – Operation Inherent Resolve international coalition,[3] and has since been part of the Autonomous Administration of North and East Syria.

In late November 2017, Hajin became ISIL's de facto capital city after they lost their Raqqa, Mayadin, Al-Qa'im, and Abu Kamal strongholds at the hands of the Syrian government, Iraq, and Kurdish-led forces respectively.

[5] In March 2018, the SDF paused the campaign against Hajin in order to defend Afrin from the invading Turkish Army, but the operation resumed by 24 April 2018.

[10] On October 31, 2018 the SDF suspended its operation in Deir ez-Zor, including their efforts against ISIL in Hajin, as a response to Turkish attacks against SDF-held areas in northern Syria.

On 14 December 2018, the SDF spokeswoman Lilwa al-Abdallah said that the military operations are ongoing to fully end ISIL and soon, we will celebrate the full liberation of Hajin.
