The motive behind the attack was not immediately clear, but China has seen a number of mass stabbings and other attacks carried out by people bearing grudges against society.
BEIJING -- More than 10 knife-wielding attackers slashed people at a train station in a southwestern city in what authorities called a terrorist attack by ethnic separatists in western China, and police fatally shot four of the assailants, leaving 33 people dead and 130 others wounded, state media said.
The attackers, most of them dressed in black, stormed the Kunming train station in Yunnan province and started attacking people Saturday evening, according to witnesses.
