The 11th Panchen Lama on Sunday condemned the mass stabbing at a train station in Southwest China's Kunming city that left 29 civilians dead.

"Those who claim the lives of themselves, or others, or any living creatures are bound for severe punishment for generation after generation," he said to Xinhua.

"Those who make every effort to protect the lives and property of the public, regardless of their own safety, have immeasurable merits and virtues," he said.

Knife-wielding assailants attacked people at the crowded square and ticket hall of Kunming Railway Station at 9:20 pm Saturday, leaving at least 29 civilians killed and over 130 injured.

Evidence at the crime scene showed that the attack was orchestrated by Xinjiang separatist forces, prompting a wave of criticisms from both at home and abroad.

The 11th Panchen Lama, Bainqen Erdini Qoigyijabu, is in Beijing to attend the annual session of the National Committee of the Chinese People's Political Consultative Conference, China's top political advisory body.
