KUNMING, China (AP) — Authorities blamed a slashing rampage that killed 29 people and wounded 143 at a train station in southern China on separatists from the country’s far west and vowed a harsh crackdown Sunday, while residents wondered why their laid-back city was targeted.

Police fatally shot four of the assailants — putting the overall death toll at 33 — and captured another after the attack late Saturday in Kunming, the capital of Yunnan province, the official Xinhua News Agency said. But authorities were searching for at least five more of the black-clad attackers.
