An additional 16 policemen were injured. This just four days before opening ceremonies for the Summer Olympics in Beijing.

"China has spoken in the past of what it calls a terrorist threat from Muslim militants in Xinjiang, but it has provided little evidence to back up its claims, says the BBC's Daniel Griffiths in Beijing."
