TOPSHOT - This picture taken on May 17, 2022 shows a view of skyline of the city centre of Saudi Arabia's capital Riyadh during a heavy dust storm. - A sandstorm engulfed Saudi Arabia's capital and other regions of the desert kingdom on May 17, hampering visibility and slowing road traffic. The thick grey haze made iconic Riyadh buildings such as Kingdom Centre nearly impossible to see from more than a few hundred metres (yards) away, though there were no announced flight delays or cancellations.
