The provinces of Deir ez-Zor, Hasakah and Raqqa, and the Manbij area in the countryside of Aleppo, which are under the control of the Syrian Democratic Forces (SDF), have been subject to a series of attacks by the Islamic State (IS) over the past few weeks. These attacks, carried out by IS-affiliated cells and locals who previously fought with IS, are targeting civilians and SDF members in those areas
IS has stepped up its operations in early 2020 after having faded away since losing its last strongholds in eastern Deir ez-Zor on March 23, 2019. These operations included directly attacking checkpoints and patrols, assassinating SDF members or collaborators, and planting improvised explosive devices (IEDs) on the roads.
