An air strike Saturday by Syrian regime ally Russia killed five civilians, including four members of the same family, in an opposition bastion in the country's northwest, a monitor said.
The Syrian Observatory for Human Rights said three children were among those killed after midnight Friday in the village of Bala in the jihadist-run Idlib region.
"A man, his wife, and their two little girls were among those killed," said the head of the Britain-based monitoring group, Rami Abdel Rahman.
An AFP correspondent at a hospital in the area saw the bodies of two of the children wrapped up in thick winter blankets.
