World's tallest tower lookout shuttered

DUBAI: The Burj Khalifa's owner said yesterday the observation deck of the world's tallest tower has been unexpectedly shut down, potentially disappointing thousands of tourists and marring the spire's image just a month after it opened.

The precise cause of the Dubai skyscraper's closure remained murky. In a brief statement responding to questions, building owner Emaar Properties blamed the closure on "unexpected high traffic", but then suggested that electrical problems were also at fault.

"Technical issues with the power supply are being worked on by the main and subcontractors and the public will be informed upon completion," the company said.
