A local Chinese worker who has friends and relatives in the region said the real cause of the continuing violence was the authorities failure to punish perpetrators of a previous attack in which several Uighurs were killed. The Chinese state terror machinery is trying to make life very difficult for native Uighurs and trying to push them out of their lands where they have become a minority due to Han transmigration & social injustice that came with it! Even the region's natural wealth is stolen.
