In the face of atrocities like the recent Houla massacre, thousands of refugees are streaming across the border from Syria into Turkey and Lebanon. The injured say it's simply not safe to seek treatment in their homeland. "All the hospitals are under Syrian control. We don't dare go there", says one man. One of the doctors helping the refugees is Syrian-born Australian, Dr Tamer Kahil, who says he just couldn't sit back and do nothing and flew to Turkey to provide medical aid. "What is happening in there is beyond belief". Patient after patient is brought to him, suffering lost limbs, gunshot wounds and the scars of beatings and torture, some requiring complicated surgery and years of rehabilitation. As Syria's death toll continues to climb, the flood of refugees escaping the bloodshed shows no sign of slowing down.
