Protests against the Syrian government and violence had been ongoing in the Syrian city of Deir ez-Zor since March 2011, as part of the wider Syrian Civil War, but large-scale clashes started following a military operation in late July 2011 to secure the city of Deir ez-Zor. The rebels took over most of the province by late 2013, leaving only small pockets of government control around the city of Deir ez-Zor.
The Deir ez-Zor offensive was executed by the Islamic State of Iraq and the Levant, also known as ISIS, against all other opposition forces in the Deir ez-Zor Governorate as part of the Inter-rebel conflict during the Syrian Civil War.
The Deir ez-Zor Governorate campaign of the Syrian civil war consists of several battles and offensives fought across the governorate of Syria:
The Deir ez-Zor offensive was a military operation launched by the Islamic State of Iraq and the Levant (ISIL) on the Deir ez-Zor air base and the surrounding areas.
The Deir ez-Zor offensive (2016) was an ISIL military operation, during which it took over the northern suburbs of Deir ez-Zor on 16 January 2016, and killed from 135 to 300 people, while also kidnapping about 400 others.
The siege of Deir ez-Zor was a large-scale siege imposed by the Islamic State of Iraq and the Levant (ISIL) against several districts in the city of Deir ez-Zor held by the Syrian Army, 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.
The Central Syria campaign, known as "Operation Khuzam," or "Lavender," was a large-scale military operation of the Syrian Army (SAA) against the Islamic State of Iraq and the Levant (ISIL) during the Syrian Civil War. Its goal was to capture the strategic oil town of Al-Sukhnah, and besiege and capture 11,000 square kilometers of ISIL territory in central Syria, after which the Syrian Army would advance towards Deir ez-Zor, and lift the three-year ISIL siege of the government's enclave in the city. Afterwards, the Syrian Army advanced towards the Islamic State's then-capital of Mayadin.
Jebel Bishri or Mount Bishri is a highland region in northeastern Syria. It is located on the border between Deir ez-Zor Governorate, Raqqa Governorate and Homs Governorate.
