At least five civilians were killed Wednesday as Russian warplanes carried out new airstrikes in Syria's Idlib de-escalation zone Wednesday, according to a Syrian civil defense group.

Axar.az reports citing Turkish media.

The Syrian opposition aircraft observatory said Russia targeted Ma’arrat al-Numan district, Kafr Rumah town, Serce village as well as Atarib district of Aleppo.

While Russian jets were carrying out airstrikes, the Assad regime's forces attacked villages in southern Idlib.

The White Helmets civil defense group announced that four civilians died due to the airstrikes and one was killed by the regime's artillery fire.

The groups said search and rescue operations are continuing in the region and feared the death toll could rise.

On Tuesday, Russian warplanes conducted airstrikes in the de-escalation zone, killing at least 26 civilians.
