The observation deck at the world’s tallest building reopened yesterday, two months after being closed by a terrifying lift drama.

Visitors were trapped for 45 minutes in February when their lift got stuck more than 120 floors above ground at the 828ft Burj Khalifa tower in Dubai.

Dozens queued for the lift yesterday, even though the cause of the breakdown is still unclear. The deck is on the 124th floor, two-thirds up the tower, which is served by 57 separate lifts.
