It took just minutes for a heavy sandstorm to wreak havoc in the ancient Silk Road city of Dunhuang in north-western China.
Wind whipped up a wall of sand, estimated to be at least 100m tall over the city in Gansu Province, on the edge of the Gobi Desert.
The sandstorm turned the sky yellow and reduced the visibility to less than 5m in some areas.
Local traffic police imposed traffic controls at toll gates and directed stranded vehicles to leave the expressway and stop in the service areas.
The video released by state broadcaster China Central Television comes after dust swept through the Chinese capital Beijing in May earlier this year.
Traffic was snarled and more than 400 flights out of the capital’s two main airports were cancelled.
Earlier this year neighbouring Mongolia was also hit by heavy sandstorms, with at least 341 people reported missing, according to China’s state news agency Xinhua.
