Knife-wielding mob kills 28 at China train station - CNN.com
I wonder who the attackers were? Yunnan is not known for a lot of seperatist violence. Most of the local Muslims are ethnically Chinese and do not seem to have any seperatist amibitions. Likewise, though the area is home to many tribal ethnic groups - some with long standing grudges against Han Chinese, I cant remember hearing about an attack of this magnitude before.
