Sweden water park: Dramatic video shows huge fire engulfing newly built attraction

Footage shows a huge fire engulfing a newly built water park in Gothenburg, Sweden.

Police say 12 people needed hospital treatment for minor injuries. Officers evacuated a hotel and offices nearby, and warned residents to stay inside because of the smoke.

The cause is still unknown, but authorities say the fire is being investigated as a "workplace accident".

The water park, which was due to open later this year, was part of an expansion of Liseberg Amusement Park.
