Security has been tightened in south-west China's Kunming following a mass knife attack, as witnesses described horrific scenes at the attack.

Several men and women burst into Kunming station, south-west China, on Saturday, stabbing people at random and wounding more than 130.

Officials have blamed separatists from the Xinjiang region for the attack.

China's security chief, Meng Jianzhu, has vowed "all-out efforts" to "severely punish terrorists".
