A wall of dust has been filmed surrounding an entire city as a sandstorm swept across the region..

"Day became night" according to witnesses as a cloud of dust as tall as a skyscraper barred towards the city of Jaisalmer in the western state of Rajasthan in India.

The city is located in the Thar Desert and is sometimes subjected to apocalyptic sandstorms that block out the sky.

In a viral video of the terrifying sandstorm on Wednesday, a wall of dust approaches a settlement as people watch in horror and amazement.

The advancing cloud is so thick it blocks out the blue sky behind it.

When the clip ends, the sandstorm is just moments from swallowing up an entire building.

In another clip, a passenger in a car records the dust cloud blotting out the entire horizon as it swells ominously towards them.

Footage also shows people anxiously recording the natural phenomenon from the roof of a building, while children chatter excitedly in the background.
