A commander for Kurdish forces battling jihadists in northern Syria urged the US-led coalition backing the offensive to prevent further Turkish strikes on their forces.
"We are asking the international coalition to intervene to stop these Turkish violations," the commander told AFP, after Turkish strikes targeting the Kurdish People's Protection Units (YPG) killed 18 people on Tuesday.
"It's unthinkable that we are fighting on a front as important as (Islamic State group bastion) Raqa while Turkish planes bomb us in the back," the commander said.
