The world's largest indoor theme park - costing over $1billion (£760million) - has opened in Abu Dhabi.

Warner Bros World opened its doors to the first visitors yesterday and the attraction honours some of the most famous cartoon characters including Bugs Bunny, Tom and Jerry and Scooby-Doo.

The desert-like climate of Abu Dhabi means the park is located inside a huge air-conditioned building with the interior designed to make it permanently resemble midday.
