Bloomberg describes bomb and knife attacks and police retaliations that “left dozens of people dead in China’s turbulent Xinjiang region, marking a new escalation of violence with the ethnic Uighur minority.” And who are the Uighur? The BBC is glad you asked: “The Uighurs are Muslims. . . . In the early part of the 20th Century, the Uighurs briefly declared independence. The region was brought under the complete control of communist China in 1949.” Hat tip to The Week.
