At least four civilians, including two children, were killed with two children severely injured in an attack by Bashar al-Assad regime forces in northwestern Idlib province, sources said on Thursday.
The missile attack targeted a moving vehicle carrying civilians in a village in Jisr-Esh-Shugur district, which falls within a de-escalation zone, Syrian Civil Defense, or White Helmets, sources told Anadolu Agency.
The children were rushed to nearby hospitals, said sources.
The Idlib de-escalation zone was forged under an agreement between Turkey and Russia. The area has been the subject of multiple cease-fire understandings, which have been frequently violated by the regime and its allies.
Syria has been embroiled in a vicious civil war since early 2011 when the regime cracked down on pro-democracy protests with unexpected ferocity.
More than 5 million civilians have since been displaced.
