The Russian-backed Syrian government said the rebels are Turkish proxies and that Turkey as broken its commitments to the peace process. Syrian government envoy Bashar al Ja’afari said, “When one of the three guarantors breaks their commitment – and I mean Turkey – this means that Turkey must be the one that is asked about the non-attendance or participation of these armed groups”.
