A rare view of the historic Riyadh papyrus and the transformation of roads into rivers in 2010.

Sinan Khalaf - Social media users have been sharing a rare video documenting the historic hailstorm that struck the Saudi capital, Riyadh, on April 3, 2010. Heavy hail covered the city's streets for the first time in decades, giving the capital a rare and exceptional white atmosphere.

The region was then subjected to severe instability, resulting in a powerful thunderstorm and heavy hail showers that battered the capital and surrounding areas.

The attached video shows a young man slipping twice in a row on the road due to the accumulation of hail, in scenes that reflect the severity and historic nature of the weather conditions.
