Syrian civil war: The Syrian Democratic Forces (SDF) resumes the Deir ez-Zor campaign in order to clear the remnants of the Islamic State of Iraq and the Levant (ISIL) from the Iraq–Syria border.

The Syrian civil war began with the Syrian revolution in March 2011, when popular discontent with the Ba'athist regime ruled by Bashar al-Assad triggered large-scale protests and pro-democracy rallies across Syria, as part of the wider Arab Spring. The Assad regime responded to the protests with lethal force, sparking a civil war. The Syrian revolution lasted almost 14 years and culminated in the fall of the Assad regime in December 2024. Many sources regard this as the end of the civil war.

The Syrian Democratic Forces (SDF) is a Kurdish-led coalition of U.S.-backed left-wing ethnic militias and rebel groups, and serves as the official military wing of the Democratic Autonomous Administration of North and East Syria. Founded on 10 October 2015, the stated mission of the SDF is to create a secular, democratic, and federalized Syria. The SDF is opposed by Turkey, who view the group as an extension of the Kurdistan Workers' Party (PKK), which it has designated a terrorist group. On 10 March 2025, the SDF agreed to integrate into Syrian state institutions under the Syrian caretaker government. Mazloum Abdi met with the committee formed by Ahmed al-Sharaa to implement the deal; further meetings were planned for April.

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.
