Turkish shelling and airstrikes killed 13 people in the town of Jandiris in Syria's Afrin region on Monday, Kurdish militia said, while a war monitoring group put the death toll at 22.
Turkey launched an offensive on Afrin in January to drive out the YPG, which it regard as a terrorist group and as an extension of a Kurdish insurgency at home.
Rojhat Roj, a spokesman for the Syrian Kurdish YPG militia in Afrin, told Reuters: "There are 13 people killed, including three children."
