A man said to be mentally ill attacked 20 people with a knife in southwestern China, killing two, authorities said. Two of the 20 injured people taken to a hospital died, the Zhenning County public security bureau said. Chen's father told authorities that his son had a history of mental illness, according to the initial statement. Prior to the attack, Chen attempted to set fire to a gas station, according to state broadcaster CCTV. Knives also have been used in attacks in the restive Xinjiang region, where authorities said in February that eight people including three assailants were killed and five injured during a knife attack in Pishan county.
