World's tallest building engulfed as Mideast sandstorms hit UAE
The world's tallest building disappeared behind a grey layer of dust on Wednesday as sandstorms that have swept the Middle East hit the United Arab Emirates, prompting weather and traffic warnings.
The 828-metre (2,716 ft, 6ins) Burj Khalifa, which towers over Dubai and is usually visible across the busy financial hub, retreated behind a curtain of airborne dirt that shrouded much of the country.
