A fire broke out Monday morning in the city of Göteborg, in one of Sweden's biggest amusement parks. The fire spread to a new aquatic area not yet open to the public, the authorities said.

Local news outlets shared photos of flames consuming a water slide and a substantial column of black smoke rising over the town.

Regional emergency services warned people to "stay indoors, close doors and stop ventilating homes", due to thick smoke being carried by the wind.

The police have reported that adjacent buildings have been evacuated, and they are assisting the emergency services in managing the situation.

As stated by the police in a press release, it is too early to determine the cause of the fire or to give an assessment of the damage.

"A major fire has erupted at the Liseberg Oceana water park (...) The fire originated in one of the water attractions outside the building and subsequently spread to the entire structure," stated Liseberg in an official statement.

The water park was part of an expansion project for the theme park and was scheduled to open later in this year.
