Survivors recount nightmare

The events of Saturday night in Kunming are deeply engraved in the mind of Xie Qiming, who narrowly escaped death in the terrorist attack at the city's railway station.

The 48-year-old policeman intervened to stop the butchering of unarmed civilians, saving many from death and injury, but he was injured in the process.

Lying in a hospital bed, his head and nose marked by serious hacking wounds - one more than 20 centimeters long - Xie recounted his actions on the day he describes as a nightmare.
