According to the Violations Documentation Center, the leading cause of death among Syrian civilians this year has been the indiscriminate use of aerial weapons – barrel bombs and chlorine gas dropped from helicopters by the Syrian army. For Syria’s many rebel groups, Assad represents the greater threat, and thus will have to be removed from power before attention can be focused on defeating the Islamic State.
据违法档案中心（Violations Documentation Center）的数据，今年叙利亚平民的主要死亡原因是无差别使用机载武器——来自叙利亚军队直升机的桶弹（barrel bomb）和氯气。对叙利亚的众多叛军集团来说，巴沙尔是更大的威胁，因此必须先把他推翻，然后才能集中精力对付伊斯兰国。
