Russian warplanes targeted residential areas in Syria's Idlib de-escalation, killing at least five civilians, a civil defense group working in the war-torn country said Monday.
The Syrian opposition aircraft targeted 18 residential areas, according to The White Helmets.
These areas include Kafr Nabl, Ehsim, Kansafra, Sufuhon, Hizareen, Kafar Aweed, Hass, Deir Sunbul villages in the south of Idlib as well as Darat Izza and Kafr Nouran towns in the west of Aleppo.
The recent advances have sent over a million civilians fleeing toward the border with Turkey, which already hosts more than 3.7 million refugees, more than any country in the world.
