BEIJING — Six people were wounded in a knife attack at a railway station in the southern Chinese city of Guangzhou on Tuesday, police said, the latest in a series of such assaults that have raised jitters around the country. No reason was given for the attack, but China's nervousness about militancy has grown since a car burst into flames on the edge of Beijing's Tiananmen Square in October, and 29 people were stabbed to death in March in the southwestern city of Kunming. The government blamed militants from the restive far-western region of Xinjiang for both those attacks. Guangzhou police “arrived quickly on the scene” on Tuesday and shot one of the attackers. Reports in state media said another person was on the run. “After verbal warnings were ineffective, police fired, hitting one male suspect holding a knife and subdued him,” Guangzhou police said on an official microblog. They did not identify the attackers and it was not clear if the number of wounded included the assailants. City newspaper the Guangzhou Journal wrote on its microblog that the attackers carried half-meter knives, wore white clothes, including white hats, and launched their assault as passengers were leaving the station. Some other reports on Chinese media outlets' microblogs said there were four attackers in total. Photos circulated online in state media showed police cordoning off an empty plaza. There was an ambulance parked there and spots of blood on the ground. An investigation was under way, police said. — Reuters
