The Bashar al-Assad regime and its allies have continued with intensified air and land attacks on civilian settlements in the Idlib deescalation zone.

In September 2018, Turkey and Russia agreed to turn Idlib into a deescalation zone in which acts of aggression are expressly prohibited. But more than 1,800 civilians there have been killed in attacks by regime and Russian forces since then as the cease-fire continues to be violated.
