Three family members, all civilians, were killed on Saturday when Russian warplanes struck the outskirts of the northwest Syrian city of Idlib, a war monitor said.
Russia has over the years repeatedly struck Syria's last main opposition bastion, but attacks killing civilians had been limited this year until an uptick in violence in late June.
"Russian air strikes this morning" to the west of Idlib left "three dead from the same family" including a woman and a child, and six others wounded, said the Syrian Observatory for Human Rights.
Four strikes hit the area where rebel bases are also present, added the Britain-based group which relies on a network of sources on the ground in Syria.
