The operation in Deir ez-Zor province resulted in the killing of six civilians, Syrian Arab News Agency (SANA) reported.
The reasons that prompted the US-backed forces to carry out actions which resulted in civilian deaths are unknown.
The governor of the Deir ez-Zor province said in February that the population in the region has increased sixfold since the end of hostilities in the area.
Syria has been ravaged by civil war since 2011, with government forces fighting numerous opposition factions and terrorist groups. The conflict has led to unprecedented strife among the civilians of the Arab republic and displaced millions of people.
Russia, alongside Turkey and Iran, acts as a guarantor of the ceasefire regime in Syria. Moscow has also been assisting Damascus in its struggle against terrorist groups, providing humanitarian aid to local residents and facilitating the return of refugees.
