Chinese officials are calling it a terrorist attack. Early this morning in the western city of Urumqi, 31 people were killed and at least 90 others injured when vehicles plowed into a crowded market and then exploded. It’s the latest in a series of attacks in China. In March, a knife attack by a group of men killed dozens in Southwest China, and just a few weeks ago, a bombing and knife attack at a train station in Urumqi, injured dozens more. China’s government have blamed the previous attacks on Uighur separatists — Uighurs are an ethnic Muslim minority who live in China’s vast Northwest region of Xinjiang, a Chinese province roughly the size of Alaska that borders Central Asia. China has so far not blamed any particular group for today’s attack.
