The "At the Top" viewing deck of Dubai's Burj Khalifa, the world's tallest building, has reopened after being closed for maintenance for almost two months.

The deck was once again open for visitors on Saturday. Emaar Properties, which developed the tower, said in a February statement that the deck would be temporarily closed for "maintenance and upgrade". A spokesman for Dubai Civil Defence later disclosed that the lift had become stuck near the 124th-floor viewing deck, trapping people for about 30 minutes.

The lavish launch of the glistering concrete, glass and steel 828-metre-high tower was part of Dubai's efforts to boost an image tarnished by its crippling debt woes. It is almost three times taller than Paris' Eiffel Tower. The viewing deck is situated at about 550 metres.
