UPDATE [14:09 CET]: The SDF media wing has released an official statement denying any ceasefire with ISIS. The statement said that the circulating document is just a part of the propaganda campaign against the SDF.
A photo of alleged ceasefire agreement between the US-backed Syrian Democratic Forces (SDF) and ISIS are circulating online.
According to the document, the SDF and ISIS have reached a ceasefire agreement to avoid clashes in eastern Syria. Furthermore, the SDF has allegedly agreed to avoid engaging ISIS units which clash with the sides not involved in the agreement – in other words, the Syrian Arab Army.
The sides will also establish a contact line, a hot line and a military coordination room in order to avoid clashes. The sides will also inform each other about military movement close to the contact line. The civilian and economic traffic will also be open between the SDF-held and ISIS-held areas.
