The siege of Deir ez-Zor was a large-scale siege imposed by the Islamic State (IS) militant group against several districts in the city of Deir ez-Zor held by the Syrian government's military forces, in an attempt to capture the city and secure full control of the Deir ez-Zor Governorate. The ISIL siege of the city lasted for almost 3 years and 2 months, after which the Syrian Army launched a successful offensive that fully recaptured the city nine weeks later.
In April 2014, IS launched a large-scale offensive against Syrian rebel forces in Deir ez-Zor governorate. This resulted in the total defeat of rebel groups in Deir ez-Zor governorate, and IS gained control of almost all of Deir ez-Zor Governorate by July 2014. Syrian government forces remained besieged in the pocket of territory they continued to control. On 10 September 2017, the siege was fully broken by Syrian government forces. After another two months of fighting, the Syrian Arab Army captured the IS-held parts of Deir ez-Zor city and its environs, by 17 November 2017.
