Eastern Hasakah offensive
The Eastern Hasakah offensive was launched in the Hasakah Governorate during the Syrian Civil War, by the Kurdish-majority People's Protection Units, Assyrian militias, and allied Arab forces against the jihadist Islamic State (ISIL or ISIS), with the intent of retaking the areas of the Jazira Canton that had been captured by ISIL. Subsequently, the Syrian Armed Forces also launched an assault against the jihadists, without coordinating with the YPG. While the Kurdish forces and the Syrian Government managed to expel the Islamic State from the vast majority of the eastern Hasakah Governorate, including the towns of Tell Hamis and Tell Brak, ISIL launched a large-scale offensive in the western part of the province in response, abducting up to 400 Assyrian Christian hostages. == Background == In February 2014, multiple towns and villages in the eastern part of the Jazira Canton came under ISIL control.
