KUNMING, China — More than 10 assailants slashed scores of people with knives at a train station in southern China in what officials said Sunday was a terrorist assault by ethnic separatists from the far west. Twenty-nine slash victims and four attackers were killed and 143 people wounded. Police fatally shot four of the assailants, captured one and were searching for the others following the attack late Saturday at the Kunming train station in Yunnan province, the official Xinhua News Agency said. State broadcaster CCTV said at least two of the attackers were women — one of the slain and the one who was captured and later brought to a hospital for treatment. Witnesses described assailants dressed in black storming the train station and slashing people indiscriminately with large knives and machetes. The attackers' identities have not been confirmed, but evidence at the scene showed that it was “a terrorist attack carried out by Xinjiang separatist forces,” Xinhua quoted the municipal government as saying. Xinhua said that in addition to the four attackers who died, 29 civilians were killed and 143 wounded. — AP
