From the Times: "State media reports have claimed that no one died in a confrontation between protesters and armed police officers in late June in western China, but numerous sources say the death toll may exceed 100"
The Silk Road China tour traveled in this Muslim region (Xinjiang Province) of China. I saw no unusual military presence (no more than you would see in a major US city). Our bus was stopped and boarded by military troops on the highway into the province, but after quickly determining we weren't Muslims, they left us to travel on. (The stop reminded me of the US Border Patrol stops I've experienced in south Texas and south Arizona.) This article makes me think I wasn't observant enough. It was also clear that our Muslim guide used great discretion in what he shared with us.
