Video footage taken moments before a catastrophic mudslide hit a border post in Tibet shows how one police officer stationed there tried to guide civilians to safety.
The clip, which shows the officer trying to direct people away from the police station at Gyirong Port, went viral online in China over the weekend.
State broadcaster CCTV said the officer, whom it named as Huang Peng, also rushed into a nearby tourist service centre to tell those inside to evacuate.
The 34-year-old, who had served at the border station for 13 years, was on duty when the disaster struck on Wednesday and there has been no word on whether he survived.
The landslide was triggered by the collapse of a glacier about 7km (4.3 miles) from the border crossing.
The debris was travelling at an estimated speed of 50 metres a second (164 feet a second) when it struck the crossing, giving people virtually no time to react.
