At least one civilian was killed in a mortar attack by Assad regime forces in the de-escalation zone in Idlib, northwestern Syria, a civil defense group said Sunday.
Two others were also injured in the attacks targeting Ein Laruz village, the White Helmets said.
Idlib falls within a de-escalation zone forged under an agreement between Turkey and Russia.
The area, lying along Turkey's southern border, has been the subject of multiple cease-fire understandings, which have frequently been violated by the Assad regime and its allies.
Syria has been locked in a vicious civil war since early 2011 when the regime cracked down on pro-democracy protests with unexpected ferocity.
