The Syrian Observatory for Human Rights opined that the incident demonstrated "increasing differences" between the two sides.[79] In early February, the Turkish Armed Forces refused to participate in joint patrols with their Russian counterparts twice. Turkish troops informed a Russian officer on 6 February that they will not take part in the patrols and they were subsequently held by Russian forces alone.[78] That same day the Syrian Arab News Agency reported that the Tell Tamer power station was put out of service as a result of what it stated were Turkish attacks against the overhead power lines that fed the station. It also alleged that Turkish attacks had caused great damage to other local infrastructure, as well as killed a number of civilians in the area.[80] Intermittent clashes and shelling occurred in early February, mostly as Turkish and pro-Turkish forces attacked SDF and government positions and made minor unsuccessful attempts to advance.
