Alleged assailant shot dead

Police shot dead a man who they say attacked several people at a train station in Xi'an, Shaanxi province, on Wednesday, officials said.

The incident occurred at about 6:30 am when the man attacked passengers in the station's ticket office with a concrete brick, the Xi'an Railway Public Security Bureau said.

Police officers on duty opened fire at the man after he ignored repeated warnings to stand down, according to the bureau's micro blog.
