Footage shows how a sandstorm engulfed buildings during rain in Riyadh, Saudi Arabia, on May 12.
Restaurant chef Armer Baring Abanto recorded the scary weather scene while talking with colleagues.
He said: ‘We are used to seeing sandstorms but this time it was also rain. It was quite hard to clean the restaurant because of the sticky dirt getting stuck to the windows.’
Sandstorms, also called dust storms, are caused by a combination of drought and strong winds. The gusts blow across dry surfaces and whip up dust and dirt in the air which forms dense clouds.
