The attack was in an oil-rich part in Iraq, but Kurds, Arabs and Turkmen are competing for power. 袭击发生在伊拉克石油丰富的地区，但是库尔德，阿拉伯和土库曼正在该地区争夺权力。
The Turkmen mountains are relatively high, but it is hard to imagine the palace remaining frozen without some sort of technical help. 土库曼山的海拔相对来说比较高，但是如果没有一定的技术支持，很难想象宫殿能够一直保持冰冻的状态。
