A series of violent riots over several days broke out on 5 July 2009 in Ürümqi, the capital city of the Xinjiang Uyghur Autonomous Region, in northwestern China. The first day's rioting, which involved at least 1,000 Uyghurs, began as a protest, but escalated into violent attacks that mainly targeted Han people.
