Children of Syria"Yarmouk, home to some eighteen thousand people, trapped by the siege, and the fight against rebel groups."
Assad's war is one that doesn't distinguish between civilians and rebels, anyone who stays in an opposition area is a target for starvation and bombing, because the régime has so little legitimacy it struggles to win any clash of arms without foreign help despite its massively superior weaponry, and so has to rely as much on inflicting as much horror as it can to force the opposition areas to depopulate. Chemical attacks aid this process too.
