Hajin in the context of "Al-Salihiyah, Deir ez-Zor Governorate"

Al-Busayrah (Arabic: الْبُصَيْرَة, romanized: al-Buṣayrah) is a town in eastern Syria, administratively part of the Deir ez-Zor Governorate. The town is located, at the confluence of the Euphrates and Khabur Rivers, southeast of Deir ez-Zor. Nearby localities include Muhassan to the northwest and al-Asharah, Mayadin and Hajin to the southeast. According to the Syria Central Bureau of Statistics (CBS), Al-Busayrah had a population of 6,199 in the 2004 census. The town was known by its Latin name, Circesium, under the Roman Empire.

During the Syrian Civil War, the city was part of the Islamic State until the Syrian Democratic Forces (SDF) captured it on 12 November 2017, bringing it under the Autonomous Administration of North and East Syria. On 6 August 2024, Syrian Army Backed Tribal Forces claimed to have captured the city amid an announced offensive in the region.

The Deir ez-Zor campaign, codenamed the al-Jazeera Storm campaign, was a military operation launched by the Syrian Democratic Forces (SDF) against the Islamic State (IS) in Syria's Deir ez-Zor Governorate in 2017 during the Syrian Civil War with the goal of capturing territory in eastern Syria, particularly east and north of the Euphrates river. The U.S.-led Combined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) anti-ISIL coalition provided extensive air support while SDF personnel composed the majority of the ground forces; OIR special forces and artillery units were also involved in the campaign.

The ground campaign stalled and was paused in early 2018 due to the Turkish military operation in Afrin, but resumed on 1 May 2018 with the new phase named by the coalition as Operation Roundup. The third phase began on 10 September 2018 but was halted due to Turkish artillery attacks on SDF positions near the Syria-Turkey border on 31 October. The SDF and the coalition announced the resumption of the offensive on 11 November. After a series of steady successes following the capture of ISIL's Hajin stronghold, and a ten-day pause for civilian evacuations, the SDF launched its final assault on ISIL's final pocket of territory on 9 February 2019 and declared victory on 23 March, concluding the campaign.
