Russian airstrikes in Syria’s northwestern region of Idlib on Thursday killed eight civilians, including five children, a war monitor said.

Axar.az reports citing five civilians from the same family were killed in Saraqeb and three others in the town of Arnaba, the Syrian Observatory for Human Rights said.

Most of Idlib and parts of Aleppo province are still controlled by factions opposed to President Bashar al-Assad’s Russian-backed regime, including a group that includes onetime members of al-Qaeda’s former Syria franchise.

“The region is witnessing very intense bombardment by Russian warplanes,” Rami Abdel Rahman, the head of the Britain-based monitoring group, said.
