Two months after it was forced to close, the observation deck of the Burj Khalifa, world's tallest skyscraper has reopened in Dubai.

After an elevator malfunction left visitors trapped more than 120 stories above the ground in February, it was shut.

It was reported that the elevator got stuck between floors for 45 minutes before rescuers dropped a ladder into the shaft so those inside could crawl out.

The Telegraph has reported that it is still unclear what caused the elevator to fail.

For Dubai, whose rulers hoped the Burj Khalifa, which officially opened in January, would be a major tourist draw and will help to revive the Gulf city-state's image as a cutting-edge Arab metropolis, the accident proved to be a major embarrassment.

The tapering silvery tower, at 2,717 feet (828 meters), ranks as not only the world's highest skyscraper, but also the tallest freestanding structure in the world.

The observation deck was the only part of the tower that opened in January and it boasts a view of Dubai's glimmering skyline, the sprawling desert and the emirate's Gulf shore. (With Inputs from Agencies)
